Milli-Q® ultrapure water systems deliver water free of organic contaminants , including hormones present in a lab's tap water, making it suitable for the most sensitive LC-MS/MS analyses.
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.
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
Assure perchlorate-free water from tap water for sensitive IC analyses. See the removal efficiencies achieved by water purification technologies in Milli-Q® systems.
See the data showing how Milli-Q® ultrapure water meets the stringent purity requirements for reliable trace element analyses of environmental samples.
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
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.
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
Ammonium determination in acidic solutions with Metrosep C Supp 2 column using the acidic binary IC eluent nitric acid/rubidium nitrate concentrate and the sodium bicarbonate/sodium carbonate suppressor regenerant.
This application note describes the fast and efficient separation of the EU’s list of 15 + 1 polynuclear aromatic hydrocarbons (PAHs) using Ascentis® Express PAH HPLC column.
This second edition of ISO 17995 has been revised by the Technical Committee ISO/TC 147, Water quality, Subcommittee SC 4, Microbiological methods, and replaces the first edition (ISO 17995:2005).
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
Learn how method EPA 533 is used for sample collection and preparation, featuring Supelclean™ ENVI-WAX™ SPE cartridges for LC-MS analysis on an Ascentis® Express PFAS HPLC Column.
Liquid Chromatography–Mass Spectrometry (LC-MS) separation of 33 PFAS (Per- and poly-fluoroalkyl substances) using a superficially porous silica particles (SPP) based Ascentis® Express C18 column.
This study reviews the suitability of ultrapure water for the IC analysis of drinking water. Inorganic ions and disinfectant by-products (DBPs) were assessed.
