Exhaust Requirements
A connection to your building exhaust / ventilation system must be provided. This could
be a fume hood or other industrial vent. Separate connections for the foreline pump
and ion source exhaust are preferred to prevent contamination of the ion source from
foreline pump oil vapor.
Ventilation must be at atmospheric or at slightly negative pressure with no positive
pressure applied.
Install the instrument in a well-ventilated laboratory. The foreline pump exhaust and ion
source exhaust contains gas, solvents, analytes, and a small amount of oil vapor. These
materials may be flammable, poisonous, or corrosive. Do not allow the exhaust to
accumulate to unsafe levels in your laboratory. Consult your local Environmental and
Safety Regulations for information about how to properly exhaust fumes from your
laboratory.
1.1.1
Foreline Pump Exhaust
Must handle up to 1 L/min
Connection to top of pump is 25.4 mm (1 in) i.d.
305 cm of flexible tubing is provided in the installation kit
This tubing can be cut to any length needed
1.1.2
Ion Source Exhaust
Must handle up to 30 L/min
Connection to ion source is 25.4 mm (1 in) i.d.
305 cm of tubing is provided in the installation kit along with two 90° elbows for routing
around the edge of the bench.
A 4 L solvent trap bottle is also provided with the instrument. This helps separate
solvent from the LC or IC from the nitrogen gas from the ion source. This tubing can be
cut to connect from the front, right of the instrument to the bottle and then from the
bottle to the building exhaust. Two 90° elbows are included to make bends around the
edge of the table if desired.
This tubing can be cut to any length needed. See Figure 5.
