Selecting the Right Water Quality for Your Applications

Water is probably the most used reagent in every laboratory. This makes its purity—and consistency of purity—critical to obtaining accurate and reproducible experimental results. This is especially true for analytical techniques (e.g., LC-MS, ICP-MS) and genomic techniques [e.g., next-generation sequencing (NGS) and CRISPR] that are becoming increasingly sensitive.

Find below a selection of Technical Articles, Application Notes and Webinars where our Lab Water experts and scientists like you discuss:

  • Water quality requirements for specific analyses
  • How to avoid water contaminants that impact results
  • How to adapt water purity to suit your needs

If you require support to determine the best water purification solution for your laboratory and its applications, we invite you to:

Water for Environmental Testing

Sensitive analytical techniques are used to detect trace contaminants in our environment and drinking water. These techniques, such as ion chromatography (IC), LC-MS and ICP-MS require reagent water to be free of the analytes being measured. Read here about ensuring optimal water quality that is critical for results reliability and accuracy in environmental testing.
