1. Aries Arsenic Reduction 1/7/2026

   Arsenic has no smell, taste, or color when dissolved in water even in high concentrations. It is a potential concern to those who live in areas with high natural deposits of arsenic, receive runoff from orchards, or from glass and electronic production waste. Long-term exposure to arsenic can cause a number of harmful effects on the human body including cancer, skin lesions, cardiovascular disease and diabetes, among others.

2. Innovative Solutions To Drinking Water Decontamination In Small And Medium Treatment Plants 9/21/2017

   Air stripping technology effectively removes VOCs, THMs, and CO2 for improved adherence to water quality regulations.

3. LC-MS/MS Analysis Of PFAS Extractables In Polyethersulfone Syringe Filters Using EPA 537.1 5/18/2022

   A key consideration for any PFAS method is to avoid contamination that can impact the accuracy of data, including those coming from sample preparation techniques such as filtration.

4. Secret To Disinfection Monitoring For High Chlorine Residual Wastewater Applications 8/2/2015

   Some wastewater applications require chlorine residuals greater than can be effectively monitored using DPD due to the oxidation of the Wurster dye to a colorless Imine. Such applications include industrial wastewater processes that inherently have a high chlorine demand thereby requiring a more robust monitoring method.

5. LC-MS Analysis Of 33 PFAS Compounds In 5 Minutes 11/4/2021

   In response to environmental testing demands for faster LC-MS analyses, the new Ascentis® Express PFAS HPLC and delay columns allow the highly efficient separation of 33 PFAS compounds in 5 minutes with reduced background contamination.

6. LC-MS Analysis Of PFAS Compounds In EPA Methods 537.1, 533 And 8327 11/4/2021

   The Ascentis Express PFAS HPLC column is designed for the separation of novel and legacy PFAS as per recent EPA methods. A specific PFAS delay column prevents background PFAS contamination from interfering with sample results in quantitative LC-MS methods.

7. Drinking Water Testing By Ion Chromatography Using Ultrapure Water 9/29/2022

   This application note demonstrates the suitability of ultrapure water produced by a Milli-Q IQ  7000 water purification system for the IC analyses of inorganic ions and DBPs in drinking water.

8. Optimization Of Water Treatment Using Zeta Potential 5/27/2020

   Drinking water in the US and developed nations of the world is treated to remove contamination of foreign materials, both mineral and organic.

9. Removal Of PFCs With Activated Carbon 12/30/2013

   In recent years, various perflorinated chemicals (PFCs) have come under increasing scrutiny due to their presence in the environment, in animals, and in human blood samples. There are two major classes of PFCs: perfluoroalkyl sulfonates such as perfluorooctanesulfonic acid (PFOS) and long chain perfluoroalkyl carboxylates such as perfluorooctanoic acid (PFOA) and perfluorononanoic acid (PFNA).

10. Bardac® LF 18 — A Novel Cooling Water Algaecide 10/23/2020

    The active ingredient in Bardac® LF 18 is dioctyl dimethyl ammonium chloride. This product comes in two concentrations: -10WT (10% w/w) and -50WT (50% w/w). Several chemical properties of this product yield key benefits that set it apart from other industrial cooling water products. It is a quaternary ammonium compound (quat). Quats are typically low cost and highly effective biocides for a broad spectrum of organisms.
