Installation Overview Video - Agilent Single Quad 5975 5977 GCMS

Introduction

This video will discuss the unique Site Prep and Installation steps needed when moving or re-installing the 5975 mass spectrometer. These include Gas Requirements, power considerations, column installation and Ion Gauge installation.

Site Requirements

The requirements for the single quad gasses are show in this table. 5 Nine purity helium or helium that is 99.999 percent pure is required. The inlet pressure on the back of the GC should be 50 to 80 PSI. Typical flows are from 20 to 50 milliliters per second. The requirements for methane are 15 to 25 PSI with typical flows around 1 to 2 milliliters per minute.

Power requirements for the 5975 require that the line voltage be within minus 10 and plus 5 percent of 120, 220 or 200 Volts AC. The current rating of the mass spectrometer is 15 amps. The maximum power consumption is 1100 Volt amps. Of the 1100 Volt amps, 400 volt amps are required by the foreline pump. One outlet is required for the Mass Spectrometer. Please note, this is only for the M.S and the GC will have it's own requirements. Power requirements are the same for all models of the 5975.

Pump Installation

When installing an M.S with a Diffusion pump, the oil cap must be removed before the unit can be powered up. After removing the cap, use the O-ring seal taped to the inside of the unit along with the clamp to install the diffusion pump onto the M S.

After removing the Roughing pump from it's box, place it on a drip tray. Install the filter onto the outlet side of the roughing pump. Fill the pump with Inland 45 oil to the correct level through the site glass. Connect the 5975 to the vacuum hose.

Connections and prep

The two shipping screws that secure the analyzer to the manifold will need to be loosened before using the instrument. After the shipping screws are loosened, you will not need to re-tighten them unless re-shipping the unit or if hydrogen is being used.

On new systems, The electron multiplier must be installed. The E M is taped underneath the manifold and inside a sealed bag that contains desiccant to prevent the multiplier from collecting moisture.

A Helium filter must be installed on the GC. The older filter is shown here. It is a RMSH-2 trap that needs to be installed vertically. The newer single quad uses a indicating chrompack filter. See the instructions with each type of filter for correct installation and usage.

A pre-tested column is shipped in the GC for new instruments. The column must be connected to the interface with the appropriate nut and ferrule. The column should extend into the source 1 to 2 millimeters.

If the system has the CI option installed, methane gas will need to be installed for checkout. The methane is normally attached to the "A" port on the back of the CI flow module. A Methane filter should be installed. If ammonia is being used, replace the filter on the roughing pump with a hose barb adapter and run the hose to a properly vented exhaust such as a fume hood.

The Micro ion gauge will need to be installed if it has been purchased. Note, the factory does not install the ion gauge and it must be installed at the customer site.
