Does Organic Modifier Choice Affect LC Separations?
Wondering if you can switch between acetonitrile and methanol and still get comparable results? In this article, we explore how differences in organic modifiers affect chromatographic performance and what to expect when switching between them in reversed-phase LC methods.
Direct, Simultaneous Analysis of Ultrashort-Chain, Alternative, and Legacy PFAS
As interest grows in monitoring a wider range of PFAS in potable and non-potable waters, efficient methodology becomes vital. Here, we developed a novel approach that provides concurrent analysis of ultrashort-chain PFAS along with alternative and legacy compounds.
Fast, Direct Analysis of Underivatized Amino Acids in Infant Formula
Reliable methods for free amino acids in baby food are needed to ensure that nutritional requirements are met. This direct analysis of underivatized amino acids provides excellent results in a faster, easier workflow compared to derivatization-based approaches.
Will Switching Column Dimensions Speed Up Sample Analyses?
Switching an LC method to a smaller column format can save time, solvent, and sample, but proper method translation is essential. Restek’s Pro EZLC method translation software makes it easy to test different scenarios from your desk and ensure success in the lab.
