In this study, SPME Arrow sample preparation was tested for the analysis of furan and alkylfurans in baby formula and coffee samples.

This fast, simple LC-MS/MS workflow for the direct analysis of polar pesticides in spinach provides good retention and peak shape over hundreds of matrix injections.

This LPGC–MS pesticides analysis utilizes a low-pressure GC column kit, comprised of a narrow restrictor column, factory coupled to a wider Rtx-5ms analytical column.  

A fast, direct method for LC–MS/MS analysis of amino acids in plasma was developed during the course of this study.  

Using a mass spectrometer as a gas chromatography (GC) detector has many advantages for compound identification and quantification, but there is another less-known benefit: speeding up analyses by using the mass spectrometry (MS) vacuum to lower pressure within the column. This technique, also known as “vacuum‑outlet GC” or “low-pressure GC–MS” (LPGC–MS), can provide significant gains for fast GC–MS.

LPGC–MS is a technique that uses the MS vacuum system, along with a specially designed column setup, to lower pressure inside the entire column, speeding up analysis.
