; File name desc_fm.08f
; Descent sequence for GCMS FM
; Based on desc_fm.07f 
; Modified by lf on 7 March 97
; to fix time problem at 1:46
; and put ACP column at 70 C rather than 80 C
; Modified again by c2 on 7 March 97
; to fix double valve ops on VS5 injections
; 
; Modified 24 Feb 97 to correct VC1-3 settings
; and to prevent fractional scans during ACP measurement
;
; Start by enabling all relevant devices
; Two seconds are required for Descent > T0 to be detected.
;
;  Note that values for the Filament 1 and 2 Ionization Potential 
; and for the GC sample selection thresholds are changed dynamically
; within the sequence and may not match the values in the AMB
;
; Modified for 30,30,40 GC temps except 60 for ACP
