Cryogenic Trapping System (CTS)

Cryogenic Trapping System (CTS)

Cryofocusing for enhanced separation performance

The GERSTEL CTS is used for cryogenic trapping and concentration of analytes. The CTS enables improved separation and lower detection limits. Following the concentration step, analytes are introduced to the GC column using a highly accurate temperature program. The CTS can be used in a single-column GC system placed at the head of the column or between the pre-column and the analytical column in a multidimensional system in order to refocus analytes prior to analytical separation.

GERSTEL GRAPHPACK technology

GERSTEL GRAPHPACK technology

GERSTEL GRAPHPACK technology was designed to provide leak-free, low dead volume, inert connections quickly and reliably for any type of connection used for gas chromatography. The same technology is used for inlet and detector connections as well as for column connections (with or without make-up gas) and multiple column splitters. GRAPHPACK fittings exist for almost all GC inlets and detectors, so a laboratory with multiple brands of GCs can use the same ferrules, adapters, and nut for all connections needs.

Selectable 1D/2D-GC/MS

An extra GC dimension at your finger tips

Gas chromatography (GC) experts rely on sharp peaks and baseline resolution to provide accurate answers. To perform chromatographic analysis of real-world samples, analysts often must deal with either complex sample types such as essential oils and petroleum fractions, or complex matrices like biological fluids, foods, sludge, or polymers. Once the sample has been prepared for analysis, separation of all the individual compounds present by means of a single chromatographic separation can be challenging due to the compounds having different ranges of polarity, boiling point, solubility, MW, and concentration. It is therefore necessary to use innovative yet robust techniques that go beyond using a single chromatographic dimension to achieve compound separation.
