GC Coupling to LC-MS Instruments - Expand your Mass Spectrometric “View” with SICRIT
SICRIT® GC-Coupling Advantages
Combination of LC-MS detection and GC separation enables more rigor and fast identification of analytes
Ionization mechanism allows to cover a broader range of analytes – previously different systems required
Soft ionization delivers molecular ion peaks and avoids complex and challenging allocation due to fragmentation
Soft ionization allows to apply advanced detection models like SWATH or Data Dependent Acquisition (DDA)
Combination with HRMS enables addition reliability in terms of substance identification
Conventional Ionization Technologies
With conventional atmospheric pressure methods, the ions are mostly formed outside the inlet of an 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.
SICRIT® Technology
The SICRIT® (Soft Ionization by Chemical Reaction In Transfer) ionization source is interfaced with the atmospheric pressure inlet of the MS and ionizes every substance which is drawn into the MS by its inherent vacuum.
