Connecting the nitrogen exhaust line B-13
To connect the nitrogen exhaust line:
1. Locate the nitrogen exhaust trap bottle in an accessible area below the
instrument.
Warning:
• Biohazardous and/or toxic LC solvents and analytes can be
carried in the nitrogen exhaust, which must be vented via the
nitrogen exhaust trap bottle and laboratory exhaust system.
The laboratory exhaust system must provide a minimum
vacuum of 0.20 kPa (2 mbar, 0.03 psi) below atmospheric
pressure (negative pressure).
• The exhaust connections can be contaminated with
biohazardous and/or toxic materials. Always wear
chemical-resistant, powder-free gloves when performing this
procedure.
• To avoid the buildup of hazardous gases, do not place the
nitrogen exhaust trap bottle in an enclosed cabinet.
Caution:
The instrument requires two separate exhaust systems: one for
nitrogen, the other for the roughing pump. Oil mist can seriously
damage the instrument if the nitrogen exhaust line connects with the
roughing pump exhaust line. Your warranty does not cover damage
caused by routing exhaust lines incorrectly.
