The JAS Preparative Fraction collector (EzPrep) for gas chromatography is the ideal solution for sample collection, component isolation and purification from complex matrices. JAS offers a robust, fully automated solution, easy to use by means of a software. 

This product has worldwide been proven and users commend highly on it's simplicity, flexibility and reliability. The automated liquid sampler injects the sample into the capillary- or packed column inlet of the gas chromatograph. After the separation, the components or component groups elute from the analytical column, are detected by the monitoring detector (FID or TCD), and a chromatogram is created. Either single peaks or groups of compounds can be isolated. The traps can be cooled or heated (optionally) for appropriate collection of low- or higher boiling compounds.

The JAS PrepLab Software allows the user to easily set and control the traps, the peak selection and peakcutting process. After being separated from the sample matrix, the components of interest can be transferred to other analysis techniques or detectors like MSD, NMR or UV/VIS.
