Drowning in water testing regulations?<\/h2>\n

Inorganic Ventures’ Platinum Cobalt Color Standard (PT-CO-500ML) is your lifeline!<\/h3>\n

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.<\/p>\n

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.<\/p>\n

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.<\/p>\n

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.<\/p>\n
