Applies to: Chromatography Smart (GC/MS) Tickets Solved: 0 Rank: 6
A small amount of IS present in the system is normal. IS can be left in the GC after running GC/MS methods. This leads to enough ions being present for the instrument to identify an IS chemical. An operator should only be concerned if the instrument is unable to detect the stimulant due to interference with IS peaks. Interference indicates an issue with the ten port valve. Call technical support for further guidance with this issue.
