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
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.
