Platinum Cobalt Color Standard

Drowning in water testing regulations?

Inorganic Ventures’ Platinum Cobalt Color Standard (PT-CO-500ML) is your lifeline!

Accurate, traceable standards are essential for regulatory compliance. If you don’t start with an accurately calibrated CRM, you can’t have confidence in your data.

The color of water and wastewater is often evaluated by determining the level of contaminants present and acts as a general indicator of water quality. For many years, the term “water white” was considered an adequate measurement of solvent color. Different expressions for defining “water white” were developed, making it clear that a more precise color standard is needed.

This need has been met using a colorimetric scaling method that measures the yellow tint in liquids compared to a qualified reference solution. Using UV/Vis spectroscopy, rather than a visual comparison, allows an analyst to more accurately and precisely determine present impurities, which is necessary for virtually colorless samples. Therefore, it is essential that the quality of the reference materials used match the high-quality performance of UV/Vis spectroscopy.

The use of the accurate starting materials (potassium chloroplatinate/cobalt chloride hexahydrate) required by the ASTM method, combined with Inorganic Ventures’ NIST traceable instrument verification methods, ensures credible, repeatable and reliable results.

While different approaches exist in the market for formulating and certifying Pt-Co color standards, the IV product starts with the right materials, follows the prescribed method and backs it up with chemical expertise, integrity and support. Here’s how you can stay afloat as water testing methods evolve.

Custom Inorganic Standards 5 years Shelf Life

Custom Multi Element inorganic standards now have a certified shelf life of up to 5 years through Transpiration Control Technology (TCT) from Inorganic Ventures. With TCT, concerns about storage and transport conditions of standards are eliminated. This saves the lab money and simplifies research by eliminating the need to constantly monitor stock levels and reorder CRMs.

Last year Inorganic Ventures already introduced the TCT technology for inorganic Stock standards. So now this technology is also available for inorganic Custom standards.

Thanks to TCT, your custom standard can always be in stock.

Transpiration refers to the wall of bottle allowing water vapor to pass through and/or through evaporation from the closed bottle opening. It leads to increase in the concentration of the CRM/RM.

Transpiration Control Technology extends the shelf life of the product. Inorganic Ventures uses a specially aluminized bag that prevents an increase in concentration until the bag is opened. The sealed TCT bag stops the loss of water vapor from the bottle when equilibrium is reached in the bag. So it is the same high quality product as you have come to expect from them, but even more improved.

To explain the problem and the technology of the solution, Inorganic Ventures has developed a series of animations explaining the frustrations surrounding perspiration. This series is by chemists for chemists.

The latest animation is called “I’m just a Custom Standard“:

Alternative for Gas Cylinders

Gas cylinders in the laboratory or workshop involve risks. Think of gas cylinders that leak with the risk of explosion as a result. And, depending on the type of gas, could potentially cause asphyxiation. In addition, moving can sometimes be a difficult and dangerous undertaking. In fact, having high-pressure cylinder bottles near your employees is an undesirable situation. Finally, there are measures that must be taken to comply with the regulations for gas cylinders.

Fortunately, there is an alternative, namely gas generators. Advantages of this compared to gas bottles are:

  • No explosion hazard
  • Easy to move
  • They don’t run out and don’t need to be replaced
  • Consistent gas purity
  • Economically beneficial

A gas generator only supplies gas when your instrument asks for it. If your instrument is on standby or turned off, the generator will not generate any gas. In the situation that an instrument has to be moved, the generator can be moved more easily. So no hassle to re-install the piping.

Nothing is more annoying if you no longer have spare gas bottles when a gas bottle runs out. It can just happen that there are delivery problems or employees have forgotten to check the gas bottles, resulting in an empty gas bottle. A generator will not run out and will continue to generate gas and will not need to be disconnected.

Perhaps the most important reason for your analysis is consistent gas purity. A gas generator supplies a constant quality of gas, while the purity of gas from a bottle can differ per bottle. That is undesirable for your instrument and analysis results.

The price of gas cylinders is increasing every year. Gas is becoming more expensive and its supply costs are increasing.

Investing in a gas generator has a payback period of approximately 6 to 12 months. This of course depends on your situation.

Instrument Solutions represents Claind Gas Generators and Purifiers. With over 40 years of experience, their gas generators provide a safer and economical way to supply clean gases. Claind’s generators generate pure Hydrogen (H2), Nitrogen (N2) or pure air (O2) for GC, LC-MS, TOC and many other applications.

If you think that gas generators can replace your gas bottles, but you want to know what is possible for your specific situation, our specialists Sina Saidifar and Jan Volkers can advise you without obligation.

6 reasons to stop preparing standards yourself

Are you tired of the limitations associated with buying standard reference materials through standard catalogs? It can be a huge waste of time; scrolling through endless product pages, each with different concentrations and matrices, without any guarantee that you will find the best analytical standards for the task at hand.

Many chemists often skip this laborious process and mix their own analytical standards. However, this method also has pitfalls. Such as extra hassle and non-negligible risks.

Fortunately, there is a better solution. Custom Certified Reference Materials (CRMs) from Inorganic Ventures. This is simple and faster way to get the right analytical reference standards for your specific applications.

A certified, NIST-traceable product delivered by elemental compatibility experts provides complete peace of mind.

It is very nice to have them take on the tough work and reduces for you the inefficiency in time associated with off-the-shelf products, as well as the risk of mixing analytical standards yourself in the lab. The technical team at Inorganic Ventures does nothing but custom produce analytical standards.

Here are the 6 reasons why CRMs custom made by a specialist are superior to analytical standards you mix yourself:

1 Mixing analytical standards is expensive

Blending single-element analytical standards into a working solution demands  both resources and time. Consider the administrative, equipment and labor costs of stocking and measuring re-order points per solution. This quickly leads to a significant ongoing investment.

Using custom analytics standards from Inorganic Ventures ensures that you only pay for what you need. This makes inventory management much easier. Our CRMs are ready for immediate use without further preparation, and you can easily dilute each standard directly from the bottle.

Inorganic Ventures offers a 100% satisfaction guarantee!

2 Documenting analytical standards is a pain

You always bear the burden of proof when mixing your own calibration standards. Laboratories that are held to the most stringent testing parameters must diligent that every standard is produced to the highest of standards. This requires an enormous degree of confidence and organization. It also requires nerves of steel if you are faced with an audit.

When using a custom product from Inorganic Ventures, all regulatory documentation and associated paperwork (CoA and SDS) is taken care of for you, and is readily available for audits. Their standards are manufactured and certified under their ISO 17025 and ISO 17034 Scopes.

3 Human error is a real risk

To err is human and even experienced chemists make mistakes. When you blend analytical standards yourself, you are bound to question the validity of your results at some point. Unfortunately, there is no room for error in the analytical industry. Perhaps you may experience compatibility issues when mixing your calibration standards because of incorrect additions or an improper matrix – or a host of other common problems.

Common human errors that may compromise the integrity of your DIY working standard include:

  • Incorrect calculations or dilutions
  • Accidental use of the wrong standard, leading to the wrong concentration
  • Improper use of the matrix, which can cause interferences
  • An unstable matrix due to poor knowledge of the required stabilizers
  • Recording the wrong weight (if preparing gravimetrically).

Inorganic Ventures’ technical team carefully checks all of their custom blends to ensure compatibility and stability of your analytical standard. All CRMs are then validated through a robust QC process to ensure absolute accuracy.

If necessary, we can advise you if/how standards can be combined to create a stable working solution. Several stability studies have been conducted to strengthen the methods.

A certified, NIST-recognized custom product provided by elemental compatibility experts provides complete peace of mind.

4 Storing analytical standards can cause even more problems

Transpiration can gradually increase the concentration of your analytical standards over time. Unfortunately, there is no way to combat this phenomenon when mixing your own working standards in-house. Reason is that it occurs as a result of water vapor entering the mixture, either through the walls of the container or through the opening.

Inorganic Ventures has developed a proprietary packaging system that effectively mitigates transpiration, preserving the integrity of the CRMs over longer periods. Transpiration Control Technology (TCT) prevents transpiration from the bottle by means of an equilibrium inside the hermetically sealed container. Analytical standards packaged in this manner maintain their integrity for up to five years after the production date. Products can be stored in the TCT bag for up to four years and then again for up to one year after removal. The time and cost savings associated with constantly replenishing supplies are effectively eliminated, significantly alleviating your storage concerns.

5 Your laboratory could be introducing contaminants

Analytical standards must be packaged in ultra-clean bottles, and sterilized laboratory equipment and clean starter materials are used to prepare the CRM. It is possible to replicate these strict cleanliness conditions in your own lab, but this is another example of the labor intensity and cost requirements of mixing calibration standards yourself.

The team at Inorganic Ventures has conducted extensive leaching studies to examine the contamination levels in all the materials used to manufacture their CRMs. They purchase the cleanest components (starting materials, weigh boats, pipettes, bottles, etc.) and properly leach them all to obtain the cleanest possible analytical standard. In doing so, they have access to a dedicated clean room with a HEPA filtration system and ultra-pure acids for production. This ensures that no environmental contaminants are introduced at any point.

6 You have nowhere to turn when you get unexpected results

It can be extremely difficult to pinpoint the source of errors when your results are disappointing. Simple errors, such as exceeding the volume, will require boiling the concentrate, usually in glass, which can only introduce more pollutants. The only solution then is to start all over again.

Inorganic Ventures’ technical support team is ready to assist with sample preparation and is highly skilled at solving problems that arise during testing. Trust their expertise when you encounter unexpected problems. Inorganic Ventures offers a 100% satisfaction guarantee!

New MultiVIEW microwave digestion system

SCP Science has launched a unique, fully automated microwave digestion tunnel; the MultiVIEW. SamplePrep for ICP-OES and/or ICP-MS analysis.

A special feature of this system is that large series of samples that are diverse in nature can be digested one after the other. This is done as sample preparation for analysis with the ICP-OES or ICP-MS. Per individual sample a different temperature controlled method can be assigned!

This is possible because the system is equipped with 12 dynamic Microwave Cavities which are individually controllable per position.

Each position is equipped with its own microwave and IR temperature sensor.

In combination with 4 AutoLOADER units, it is possible to automatically digest up to 300 samples in succession.

The system comes with an integrated 15″ color Touch Screen that clearly displays all operational parameters. The screen has a user-friendly intuitive interface that shows the digestion parameters during the run and allows you to change or stop the run at any time.

If it is necessary to zoom in on an individual sample, you can. You can view a sample on a full screen with maximum detail.  For your information, the intensity of the microwave power is also displayed.
