Thanks for the Agilent Technologies, Inc.Note: In general, DO NOT need to turn off the GC-MSD unless you are sure will not use the instrument for several days. General, depends on the turbo pump tech, it takes 2-4 hours for theｔurn On the GC-MSD system, need 1 hour to turn off the instrument. Set up an “On-Hold” method to make sure instrument is standby to work next day. Call me if need some guild.
