Developing an HPLC method for quantifying ephedrine HCl and pseudoephedrine HCl in traditional Chinese medicine (TCM) with a Discovery® C18 column to report: chromatographic data, linearity, specificity and repeatability, LOD and LOQ.
HPLC method to analyze ephedrine HCl and pseudoephedrine HCl in traditional Chinese medicine (TCM) with a Purospher® RP-18e colμmn to report chromatographic data, linearity, specificity and repeatability and LOD and LOQ.
Experience effective immobilization of protein A on wide-pore epoxy-modified silica monoliths for mAb separation, showcasing the efficiency of Chromolith® WP 300 columns in achieving faster and highly reproducible biomolecule separations.
Following the new USP monograph for Famciclovir Tablets, Purospher™ STAR RP-8 endcapped HPLC columns can be used to monitor organic impurities in Famciclovir tablet formulations. Famciclovir is an antiviral drug indicated for the treatment of herpes zoster, herpes simplex virus 2 (genital herpes), herpes labialis (cold sores), etc.
Sildenafil, sold under the brand name Viagra, among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension.
Straightforward HPTLC-MS analysis of lactose in dairy products (milk or yoghurt) using only protein crash, centrifugation and dilution as sample preparation.
This paper illustrates the setting up of a Lopinavir assay following European pharmacopoeia guidelines (10.2), and using a shorter column packed with smaller particles. The described assay saves valuable time and improves separation efficiency, which typically translates to better method performance.
