USP chapter 467 and Ph Eur Chapter 2.4.24 designate the maximum allowed residual solventlimits to ensure pharmaceutical products are free of impurities that could be harmful to an end-user. When analyzing for organic volitile impurities via the GC-Headspace technique, it is imperative that the solvents used do not contribute extraneous peaks, or interfere with the analytes being investigated.

The analysis of PFAs (perfluoroalkyl and polyfluoroalkyl substances) is now a requirement in specific EPA regulations. Bioaccumulation of PFA compounds is suspected to lead to undesirable health outcomes, making it necessary to detect and quantify them in various matrices, including but not limited to, water, food, and soil.

UHPLC is a growing technique in pharma, quality control, organic synthesis, environmental and genomics/proteomics. This technique offers the advantage of being up to five-fold faster and using less solvents than traditional HPLC while still providing the detection, identification and quantification of complex matrixes.

GFS Chemicals manufactures and distills acids to meet rigorous standards, from ACS grades for everyday use, to ultra-low levels of trace impurities for trace metal and impurity testing. Our product offering clearly delineates acids and their grades to simplify the offering to customers, while covering a wide array of applications in the lab.

In the 60’s, no one could manufacture perchloric acid clean enough to digest lunar samples, so GFS Chemicals built an acid distillation plant to serve the U.S. Space Program, establishing our expertise in high purity acid manufacturing. Our second acid plant was finished in 2021, filling a need for a U.S. based manufacturer that reliably supplies trace metal acids to half of the U.S. population in three days or less. Much has changed over the last fifty years and our entire process is now controlled by cutting-edge technology. Advanced process controls and analytics ensure Veritas Acids are ultrapure every time.

Using the highest quality solutions in your testing is the best way to control consistency and accuracy - and it all starts with water. GFS Chemicals’ ultrapure water is produced using a combination of proprietary techniques and bottled in an ISO 4 environment. The result is water that is virtually free from impurities, including organic and inorganic contaminants. Meeting ASTM Type 1 water requirements, each lot is analyzed for 65 impurities. GFS Chemicals’ new ultrapure water and acids will minimize the variability in your results and decrease instrument and sample contamination
