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.
实验方案
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.
