Efficient focusing

If you have difficulties focusing your peaks, getting a good peak shape, or are speculating into a Selective 1D/2D system:

The GERSTEL CTS is used for cryogenic trapping and concentration of analytes. The CTS enables improved separation, narrower and sharper peaks and therefore lower detection limits. Following the focusing step, analytes are introduced to the GC column using a highly accurate temperature program. 

For even lower detection limits, analytes from multiple injections can be concentrated onto the CTS. 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 (we have the expertise to build the system for you).
