- Technical Specifications
GPC (Gel Permeation Chromatography) cleanup has proven the most versatile and convenient post-extraction sample cleanup technique for a wide range of sample matrices. GPC cleanup eliminates high molecular weight compounds such as lipids, pigments, proteins, and polymers from organic sample extracts prior to GC or GC/MS analysis. Failure to remove these interfering compounds can shorten column life and increase analytical downtime.
The AutoClean, LabTech’s GPC system, automates the GPC cleanup process for high throughput with complete reliability in a single system. Designed for reproducibility and ease-of-use, the AutoClean integrates an autosampler, allowing up to 120 samples to be automatically cleaned and collected. Sample extracts are transferred into vials and then placed in the sample tray on the autosampler module. Samples are then automatedally drawn up through precise sample loops and injected onto the GPC column for separation. High-molecular-weight materials elute from the column first and are discarded. The remaining sample with the analyte of interest collect in the sample flask on the collection tray for further processing. Late-eluting fractions, such as sulfur in soil samples, can be directed to waste after collecting the compounds of interest. The system then completely rinses in preparation for the next sample.
