App Notes

You used to have to deal with chromatographic band broadening, low sensitivity, and long run times caused by classical fully porous silica.

As an abundant, inexpensive alternative to helium, which is becoming increasingly more costly, there is no reason why nitrogen cannot be used for BAC analysis in place of helium.

A 3D PCA plot visually showed that ionic liquid columns fill an empty area of the available selectivity space, which should clearly enhance the separation capacity of the GC technique.

The paracetamol content of three highly complex matrices: suppositories, syrup, pills and of several standards was analyzed.

This application note describes the extraction of 25-hydroxy vitamin D from serum, prior to LC-MS/MS analysis.

This application note outlines a simple, fast and cost-effective method for the determination of 7 neonicotinoid pesticides in honey.

Using Compact Mass Spectrometry for product control and law enforcement of cannabis related plant products

In this application note the main advantages and the high performance of the pure polymer-based columns SUGAR SH and RSpak KC for ion exclusion chromatography are discussed. In addition, different applications, i.e. the separation of saccharides and organic acids in food, of both types are described.

This poster describes how fast gas GC with time-of-flight mass spectrometry (TOF MS) can allow identification of both target environmental pollutants and unknowns in a single, rapid analysis.

Separations of structurally similar compounds such as vitamin D2 and vitamin D3 are very challenging.
