CTC / Gerstel Analytics GC Combi PAL Headspace and Liquid Sampler

CTC / Gerstel Analytics GC Combi PAL Headspace and Liquid Sampler

The CombiPAL autosampler makes sample processing simple and transparent. This autosampler meets today’s laboratory equipment requirements for speed, flexibility and precision. The CombiPAL GC sample injection system can be configured to combine liquid, headspace and SPME injection in one single instrument. This capability allows quick switching from one application to another on the same GC workstation. Regardless if your samples are processed in headspace, liquid or SPME mode, or if your method requires split/splitless or on column injection, your new instrument setup is ready in a few minutes. The CombiPAL provides powerful working capabilities, an investment that grows with your expanding needs.

Solid Phase Micro Extraction (SPME) (Purchase required)
SPME has become a practical alternative for GC sample preparation. This mode reduces sample preparation time and eliminates the need for large volumes of extraction solvents. With SPME, analytes establish equilibria among the sample matrices. Analytes are adsorbed onto the stationary phases coated on either fused silica or metal fibers then are thermally desorbed from the fiber to a GC inlet onto a capillary column. No solvent injection and analytes rapidly desorbed onto the column improve minimum detection limits and maintain resolution.
