General description

The Ascentis® Express biphenyl phase chemistry offers alternative selectivity for pharmaceutical analytes and drug metabolites that are not well retained or difficult to resolve on traditional alkyl (C18) and phenyl bonded phases. Ascentis Express HPLC columns, through the use of Fused-Core® particle technology, can provide you with both the high speed and high efficiencies of sub-2 ?m particles while maintaining lower backpressures. The combination of high efficiency and low backpressure benefits UHPLC users, as well as conventional HPLC users. Visit the Ascentis Express home page for more information on this new column technology.

An online SPE-LC/MS method has been developed for the rapid detection of thyroid hormones in human serum with minimal hands on effort and time-consuming steps.

Tetrahydrocannabinolic acid A solution, 1.0 mg/mL in acetonitrile, ampule of 1 mL, certified reference material.

The bonded, densely endcapped, dimethyl-biphenyl stationary phase of Ascentis® Express 90 Å Biphenyl, based on fused-core particles, provides a stable, reversed phase packing with enhanced π-π and mild steric interactions due to the two sequential phenyl groups bonded to the base silica.

Potency testing in marijuana-infused edibles is an important problem that analytical labs are facing due to the complexity of the involved matrices. Concentration of active ingredients in these edibles can range from a few parts per million to 3.5 parts per thousand. This application demonstrates the extraction and HPLC-UV analysis of the active compounds.

Thyroid hormones play critical roles in the regulation of biological processes, such as growth, metabolism, protein synthesis, and brain development. For a clinical laboratory, fast and reliable measurements of total hormone levels are important for the diagnosis and monitoring of thyroid diseases.

Rapid potency testing of marijuana-infused edibles using LC/MS on a biphenyl stationary phase detected eleven cannabinoids.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
