Splitsplitless injection

Jul 17, 2017 · The only thing that is important is the mass of analyte that you put on the column - if you are doing liquid injections, which the guidance assumes you are, that is the injection volume times the mass/volume concentration of what you are injecting. Since you are doing SPME the guidance as given is irrelevant..

A basic video about the concept of the split and splitless injection. Good video for beginners. Learn the basic concept of Gas Chromatography 1. introduction. The contraceptive injection is a hormone injection that prevents pregnancy. The injection works for 12 weeks. The injection contains depot medroxyprogesterone acetate (DMPA).

So, the advantages of the split/splitless injection are combined with those of the cold injection onto the column. It becomes possible to inject greater volumes with standard syringies avoiding needle-induced discrimination. Furthermore, compounds having low boiling points (particularly solvents) can be eliminated.




We also compared quantitative data obtained by programmed-split/splitless (PSS) and splitless injection modes. PSS is an injection method similar to the PTV; however, with the former,.

Compounds were desorbed at 260°C, temperature equal for all fibres in a split/splitless injection port, equiped with a 0·75 mm SPME liner and working in a splitless mode. Analysis was performed in programmed temperature: 40°C for 3 min, then 8°C min −1 to 280°C. Gas chromatography/mass spectrometry (GC/MS) interface temperature was set.
