Trapped ion mobility spectrometry and PASEF enable in-depth lipidomics from minimal sample amounts
A comprehensive characterization of the lipidome from limited starting material remains very challenging. Here we report a high-sensitivity lipidomics workflow based on nanoflow liquid chromatography and trapped ion mobility spectrometry (TIMS).

Effect of sodium bicarbonate residue on some characteristics of processed meat products
Using sodium bicarbonate (SB) in cooking meat products is a controversial subject. The aim of this study was to estimate an effect of different SB concentrations on the quality characteristics and organoleptic properties of meat in Kubideh Kebab, an ...

Quantification of DNA Products Using Ion-Pair Reverse Phase Liquid Chromatography [PDF]
The transcription of DNA via RNA polymerases is a fundamental process in cellular systems. In eukaryotic cells, we observe transcription in the nucleus (via genomic DNA) as well as in the mitochondria (via mitochondrial DNA).

Peer Reviewed: Ion Chromatography Retrospective [PDF]
In the 1960s and early 1970s, various chromatographic methods were used to separate low molecular weight inorganic anions and cations; however, the separations were only moderately efficient, and detecting those analytes that did not absorb UV radiation was rather difficult. It was more common for researchers to determine these analytes by wet-chemical
