SGS’S Dr. Bharat Chandramouli to Present on GC-MS/MS Approaches for Chlorinated POPs Analysis at Waters Online Dioxin Symposium​, September 22

GC-HRMS is currently used to analyze chlorinated dioxins and furans, PCBs, pesticides and other halogenated compounds. New approaches, such as GC-MS/MS, require compatibility with existing methods and quality criteria to demonstrate equivalency with GC-HRMS data. Bharat Chandramouli, Ph. D., Environmental Laboratory Product Manager, North America at SGS and Coreen Hamilton, Ph. D., Senior Scientist, SGS […]

SGS’S DR. BHARAT CHANDRAMOULI TO PRESENT ON GC-MS/MS APPROACHES FOR CHLORINATED POPS ANALYSIS AT NEMC VIRTUAL CONFERENCE, AUGUST 18

GC-HRMS is currently used to analyze chlorinated dioxins and furans, PCBs, pesticides and other chlorinated and brominated contaminants. New approaches, such as GC-MS/MS, show promise as alternatives but require new development and the testing of compatibility with existing methods and quality criteria to demonstrate equivalency with GC-HRMS data. SGS AXYS has been at the forefront […]

DR. BHARAT CHANDRAMOULI OF SGS TO PRESENT ON PFAS MONITORING AT WASTEWATER TREATMENT PLANTS AT ECOS VIRTUAL CONFERENCE, JULY 29

SGS AXYS is a leader in the measurement of pharmaceuticals and personal care products (PPCPs) in the environment. Our methods were used as the basis for EPA Method 1694 in 2007 and these isotope-dilution LC-MS/MS PPCPs methods has since expanded to include close to 200 drugs, metabolites, hormones and personal care products. From natural and […]

Bile Acids Interferences in PFAS Analysis

Bile acids structure and name

Can bile acids found in plasma, eggs, liver and other biological samples interfere with PFAS analysis? Yes! But there are ways to avoid these interferences and produce reliable data. Bile acids and their salts are either synthesized in the liver or formed from bacterial activity. They are the major constituents of bile and help digest […]

SGS AXYS Data Used to Assess Phthalate Levels in Children

Phthalates, used as plasticizers in many plastics including polyethylene, polypropylene and more, have been associated with endocrine disruption. But, given their ubiquity in the environment, it is challenging to really pinpoint exposure in humans. Phthalates are metabolized in the body into monophthalate ester metabolites and excreted in urine. So, measuring these phthalate ester metabolites in […]
