Maximum Length of Cables and Hoses

The distance between system modules may be limited by some of the cabling
and the vent or vacuum hoses.
• The length of the Agilent-supplied remote cable is 2 meters (6.6 feet).
• The length of the Agilent-supplied LAN cable is 10 meters (32.8 feet).
• The lengths of the power cords are 2 meters (6.6 feet).
• A quadrupole GC/MS system foreline pump can be located on the

relatively vibration free. Do not put the rough pump on your laboratory bench with the
7200/7250 Q-TOF GC/MS due to the vibration that the pump creates. Vibration can
lead to a loss of mass accuracy and resolution.

connected by a hose. The hose is stiff and cannot be bent sharply. The
length of the vacuum hose is 130 cm (4.24 feet) from the high vacuum pump
to the foreline pump, while the length of the foreline pump power cord is
