WebApr 10, 2024 · The temperatures of the MS quadrupole and the ion source (electron impact) were set to 150 and 230°C, respectively. The collision energy was set to 70 eV. Mass data were acquired in full scan mode (m/z 50–450), and the solvent delay time was set to 5 min. WebRoughly speaking, compounds with low boiling points tend to elute at short retention times. The distribution coefficient determines the order of elution from column. When you put …

Weba. Solvent delay. This tells the mass spec when to start detecting. One wants the solvent to have come off the gc before any efluent is sent to the ms source. A one minute solvent delay is good of diethyl ether; a two minutes solvent delay for solvents with bp's below 100°C and a higher solvent delay for solvents like DMSO. b. Mass ranges.
