Three hormones were detected by LC-MS/MS in the tap water of different laboratories. After purification by Milli-Q® water purification systems, the hormones were no longer detected in the product ultrapure water.
The new EN ISO 11133:2014 quality-assured culture media for food and water testing to enhance consumer safety. The ultimate aim of the new standard is to further improve the safety of the food and beverage products we consume.
Nonylphenols (NP) are ubiquitous substances that have been detected in highly diverse foodstuff. As breakdown products of nonylphenol ethoxylates, NP could end up in the aquatic environment. This article presents a rapid method for NP detection in surface water
This second edition of ISO 17995 has been technically revised by the Technical Committee ISO/TC 147, Water quality, Subcommittee SC 4, Microbiological methods, and cancels and replaces the first edition (ISO 17995:2005).
EN ISO 11133:2014 - Mandatory standard for media preparation, production, storage and performance testing. In May 2014, the International Organization for Standardization (ISO) published the revised EN ISO 11133, which is now a full standard and as such, mandatory for
LC-MS method-based separation and determination of 32 short-chain and long-chain PFAS (Per- and poly-fluoroalkyl substances) compounds from drinking water following 3 EPA methods Method 533, 537, and 537.1. EPA 8327
The Safe Drinking Water Act reflects the primary drinking water regulation. Drinking water here means finished drinking water from the plant and the distribution lines. But the Safe Drinking Water Act covers also the ground water sources for raw water
See how two water sources compare when preparing and performance testing microbiological culture media acc. to EN ISO 11133: centrally purified water vs. water from a Milli-Q® IX system were assessed. Tests included media specific for Listeria and Salmonella pathogens.
This page provides tables that list the products used in promulgated methods for Per- and polyfluoroalkyl substances (PFAS) analysis, organized by method and step for easy reference. As new methods are released, this page will be updated.
