Say goodbye to DIY with ready-to-use reagents for discrete analysers! Until now, pre-mixed reagents have not been offered in a sustainable, reliable way. Through extensive research and development, Inorganic Ventures has created the perfect alternative to in-house reagents. These products require no preparation time, improving your efficiency and minimising errors.
Besides saving time, these reagents offer method flexibility, batch-to-batch consistency and comprehensive stability data.
As always, these products are packaged in Inorganic Ventures’ Transpiration Control Technology (TCT) for protection from light and you can have them in your home within 2 weeks.

(*) Keep an eye on our website. The range of reagents will be further expanded this year!
Shelf life
As this is a new product, producer Inorganic Ventures is conducting rolling stability studies. The shelf life is now at 9 months because the study is now 9 months in progress. During the study, every three months the stability is extended by three months until the maximum shelf life is reached, which is not clear at the moment.

Win back time and increase your lab’s efficiency with ready-to-use reagents! FAQs
1. For which instruments are the discrete analysis reagents designed?
Our discrete reagents can be used on the following instruments:
2. I am using a segmented flow analyser. Are the reagents of your discrete analyzer compatible with this instrument?
The reagents for discrete analysers can work on your segmented flow analyser. Please refer to the Method Chemistry Sheets (links above) for each product for detailed product composition. Please contact us directly with any questions.
3. Does shipment to or through locations with hot temperatures cause stability problems with the reagents?
Our stability studies have shown that some reagents can be sensitive to heat. All our products undergo transport stability to ensure that temporary exposure to heat does not affect product performance. At this time, we recommend refrigerated storage of discrete analytical reagents until our stability studies are completed and storage recommendations on the product coAs are reviewed.
4. Transpiration Control Technology (TCT) extends the shelf life of Inorganic Ventures’ standards by up to five years. Do the Discrete Analyzer Reagents have the same five-year shelf life?
Unfortunately no. Our standards have a chemical stability of 5 years and the TCT pouch ensures that the concentration does not change due to perspiration. The discrete analytical reagents are still being tested for chemical stability and we are currently using the TCT pouch to protect against light. Currently, all our discrete reagents have a shelf life of 9 months and we will adjust the shelf life every 3 months for the duration of stability testing.
5. The 500ml volume is not suitable for my testing needs. Does Inorganic Ventures offer other bottle sizes?
Whether you need a custom volume size or a unique formulation, we are happy to work with you to meet your needs. To get started, contact us!
6. I am not sure if I am really saving time and money by switching from reagents made in my lab to ready-made reagents from Inorganic Ventures. How do I know for sure?
Schedule an appointment with our Product Manager Jeroen van Boxtel and we’ll walk you through your individual time and money savings! We have a savings calculator ready and you can take the findings to your team.
7. My standard operating procedure (SOP) is very complex. I am not sure if I can easily add new reagents to the workflow. Can you help?
No problem! Inorganic Ventures’ technicians specialise in SOP development and implementation. Make an appointment through us with one of these chemists for technical support to discuss your specific SOP requirements.
8. I am following alternative methods on my discrete analyser, are there other methods available?
We are launching more reagents for discrete analysers in the coming months! The next ones – Ammonia. Alkalinity, Hardness, Chromium and more to follow. Let us know which ones you are looking for!
