Note
Electrical connections are displayed on the type plate on the rear panel of
the system.
4.2 Installation conditions
An appropriate location for installation of the GC 5000 should be vibration-
free as far as possible. The system is suitable to run in measurement
cabinets or containers.
Make sure that the ambient temperature should be in a temperature range
between 5°C and 35°C. Air conditioning has to be provided, if the
temperature exceeds that range. Keep in mind that the analyzer produces
waste heat, which has to be dissipated effectively.
Note
The ambient temperature during operation of the instrument has to be at
minimum 10°C below the starting temperature of the GC oven program in
order to guarantee a reliable cooling down of the GC oven at the end of
each cycle.
4.3 Gas connections
Bulkhead connectors for tube diameters of 1/8’’ (Swagelok) are provided to
connect the gas lines to the GC 5000.
The gas circuit diagrams as well as the type plate on the rear panel of the
GC 5000 indicate the correct port for each gas line to be connected.
•
Use 1/8’’ PFA hose or stainless steel tubing to connect the gas lines.
•
Use functional, leak proof and clean tubing only to connect the required
gases to the GC 5000.
•
Pressure of combustion air: 2 bar (necessary for the FID flame).
•
Pressure of the hydrogen: approx. 2 bar (necessary for the FID flame).
•
Pressure of nitrogen: approx. 3 bar
Caution!
Hydrogen is combustible and explosive; avoid wrong gas connections.
Disregard may result in damage to the system or cause malfunction and
wrong detection results. All gas connections to the GC 5000 BTX are
labeled. Make sure that the supply of the gases (hydrogen, nitrogen,
combustion air) is secured and the correct port for each gas line is used
before switching on the system.
Caution!
Use nitrogen 5.0 (99.999%, GC grade quality) as carrier gas and hydrogen
5.0 as combustion gas. Make sure that the combustion air is dry and free of
oil traces. Pure gases prevent the system from contamination.
