Application Notes: GC
Equivalent GC Systems Performance for Regulatory Method Compliance and Validation
Methods migration from updating analytical equipment can be a time consuming task. This paper shows many examples of method compatibility and analytical equivalency.
Application Note : Analysis of e-liquids According to ISO 20714
In this application note we demonstrate the excellent performance of Sapiens-624MS columns for the analysis of e-liquids based on ISO 20714.
Analysis of United States Pharmacopeia (USP) Grade Isopropyl Alcohol Impurities
This application note describes two methods for isopropyl alcohol impurities detection: USP recommended 42-min analysis, and a speed-optimized method in less than 6 min.
PFAS Analysis Using a pH-Variable LC Mobile-Phase Gradient v3
A novel LC approach to manipulate the chromatography of closely related PFAS analytes to separate co-elutes and avoid matrix interferences.
The Effect of Draw-Out Lens Diameter
Investigating the effect of hydrogen and helium carrier gas across a range of column flow rates with different draw-out lenses for essential oil and volatile analysis
