Foreline Pump Requirements for Systems
Including an MSD
1 If using a 7200 or 7250 Q-TOF MS, the length of the quadrupole vacuum hose is 130 cm
(4 ft 3-inch) from the high vacuum pump to the foreline pump, and the length of the foreline
pump power cord is 2 m (6 ft 6-inch).
2 If your bench abuts a wall, drill 4 cm (1.5-inch) diameter holes through the rear of the bench
for the vacuum hose and power cord.
Make sure the 7200/7250 Q-TOF GC/MS foreline pump is located where it is not likely to be
touched by operators.
