Automated Liner Exchange for GC injectors

摘要

The system described herein for automatic exchange of PTV inlet liners enables automated GC analysis of samples or extracts with a high content of high boiling substances or suspended matter.rnThe chosen application, determining pesticides in fruits and vegetables with QuEChERS sample preparation, demonstrates that a reduction of sample preparation steps combined with a GC system which tolerates injection of solutions with a high matrix content is a powerful solution. Laboratory time for sample preparation is reduced dramatically and at the same time a high sample throughput for the analytical instrument is ensured.
