Optimization of the qualitative and quantitative analysis

The use of a vacuum ultraviolet (VUV) spectrovial gc pricemeter as a benchtop detector for gas chromatography (GC) has increased since commercial implementation in 2014 [1,2]. VUV allows for the detection of virtually any analyte by σ and π bond absorption of UV light in the traditional UV, deep UV, and far UV regions [ [1] , [2] , [3] ].
