2014/05/26 · I've noticed that when I fill a headspace vial with a standard gas mixture, the area of the peaks are dependent on the pressure in the headspace vial before sampling. I thought the sampler I'm using (Aijiren ) vents to atmospheric pressure in the loop loading/pressurization step, so why does the small amount of overpressure in the standard vial make any difference?
GC-MS sample preparation can sometimes occur using LC-MS, as the following figure shows. Furthermore, advances in GC-MS technology, such as the introduction of the Orbitrap mass analyzer, have enabled analysis of larger and more complex compounds, propelling GC-MS into traditional LC-MS fields such as metabolomics.
