Soft Ionization by Chemical Reaction In Transfer

# Mass Spectrometry

Mass spectrometry is one of the most powerful techniques in chemical analysis. Mass spectrometers enable to detect and characterize substances based on the mass-to-charge ratio of their molecules. To do so, MS comprise two basic components: an ionization source and a mass analyzer.

 
 

# Ionization Source

With conventional atmospheric pressure methods, the ions are mostly formed outside the inlet of a MS. This implies that the substance to be analyzed (e.g. coffee) cannot be analyzed directly, but is usually "sprayed" into the MS in the form of a sample (liquid extract) via the ionization source.

Ionization Source

The patented SICRIT ionization source extends the atmospheric pressure inlet of the MS and ionizes all molecules which are drawn into the MS by its inherent vacuum. Due to the flow-through design of the ionization source, it is dedicated for online-monitoring of volatiles without any consumables as well as for demanding hyphenation techniques.
