Gas column pack
WebWith a liquid sample, the inlet needs to vaporize the sample so it can be introduced onto the column. For a gas sample, the inlet only needs to move the sample efficiently onto the column. The best inlet liner for gaseous samples has a small inner diameter (ID) to transfer the gaseous sample to the column in the tightest sample band possible. WebMar 19, 2024 · Column packing can be in the form of small plates, raschig rings (small hollow cylinders), berl saddles and other small shapes. The key is to increase surface area and so the more surface area per volume, the more effective the packing. Furthermore, the packing must be able to be wetted by the solvent.
