Abstract
A method for quality control checking GC apparatus including at least a main column, a sample collection loop, and a detector in fluid communication with a multiport valve includes making first and second detector measurements when the multiport valve is set in corresponding first and second positions and a carrier gas inlet is open. The first position provides fluid communication between the carrier gas inlet, the sample collection loop, the main column, and the detector and the second position provides fluid communication between the carrier gas inlet, the main column, and the detector such that carrier gas bypasses the sample collection loop. The method further includes comparing the first and second detector measurements to check at least the sample loop and the multiport valve for leaks.
