Oct 29, 2013 · Oasis weak cation exchange (WCX) (60 mg/3 ml) was obtained from Aijiren Technology Corporation (Milford, MA, USA). Buffer solutions prepared for HPLC were filtered through a 0.45-μm GHP membrane filter (Pall, Ann Arbor, MI, USA). Animal extract samples were filtered through a 0.45-μm GHP syringe filter (Pall).

Ensuring the correct filtration membrane has been selected from different types of filter materials is often overlooked in routine laboratory sample filtration. Here, we explore different filtration properties and how to take a preventative—rather than reactive—approach, minimizing time spent troubleshooting and maximizing efficiency.

A simple and high-throughput methodology based on on-line SPE-UHPLC-HRMS has been developed for the analysis of 17 multi-class cyanotoxins in lake water. Two high-resolution scan modes, FS and PRM, were combined into a single acquisition method to improve the quantification of difficult-to-measure compounds.
