Separation of Semaglutide and Liraglutide on NanoPak-C All Carbon HPLC columns

NanoPak-C All carbon columns' features include pH and temperature stability, as well as tunable properties (selectivity, pore size, surface area). These features improve the separation and purification performance and reduce operational and maintenance costs. This note summarizes the optimal methods for the HPLC separation of semaglutide and liraglutide under acidic and alkaline conditions.

NanoPak-C All Carbon solid phase extraction (SPE) of Organochlorine Pesticide from Trace
Amounts of Environmental Samples

Organochlorine pesticides (OCPs) are synthetic chlorinated hydrocarbon derivatives widely used in global agriculture. Due to their toxicity, OCPs pose human health and environmental concerns. Complex matrices hinder the detection and quantification of OCPs with liquid chromatography methods (column fouling and baseline noise). Thus, solid-phase Extraction (SPE) is a standard sample preparation method to clean up environmental samples and isolate OCPs before their introduction into chromatography systems. There is a shortage of SPE techniques to extract OCPs from small quantities of environmental samples. We present an optimized method to prepare samples using solid phase extraction to detect 15 OCPs in small amounts (100 mg soil and 200 µL river water) of environmental samples.
