Solvent delay in gc-ms
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.
