HP 5972A MSD Mass Spectrometer

The HP 5972A is a stand-alone capillary GC detector designed for use with the HP 5890 Series II Gas Chromatograph. It includes a high efficiency electron impact ion source, monolithic hyperbolic quartz quadrupole mass filter, quick-change electron multiplier, new drive electronics with the second generation MS control card ( Smart Card II ) and a high-reliability vacuum system. The HP 5972A is similar in design to the HP 5971A, yet it incorporates several new features and improvements.

Specifications:

Temperature control: Ion source/analyzer temperature is controlled by a fixed temperature thermostatic controller. Ion source temperature is maintained at about 180-250° C. Interface temperature is controlled by the gas chromatograph through the auxiliary zone controller or through a detector zone controller. Other external temperature control is also possible. Recommended interface operating temperature is from 100 to 300° C.

GC interface: Two options available are a capillary direct interface and an open-split interface. With the capillary direct interface, the fused silica capillary column is inserted directly into the ion source. The interface options are offered in three versions. The 68 mm interface is designed for the HP 5710 or 5790 Series GCs. The 94 mm interface is for the HP 5880 GC, and the 214 mm interface is for the HP 5890 GC.

Temperature environment: The MSD will operate within specifications in a temperature environment of 15 to 35° C.

Carrier Gas: A regulated supply of high purity GC carrier gas is required. Minimum purity of 99.9995% is recommended. Molecular sieve trap is also recommended.

Power: The detector mainframe operates on 100,120,220,240 volts. The line frequency is 48-66 Hz.

Heat Dissipation: Approximately 7000 BTU/hour.
