12 | DBDID | 892J009MNAE
Using a VOM meter, verify the voltage between the Bias test point and
chassis ground on the Power Supply Board. The voltage should be a
stable +10 volts DC.
4 Specifications
Note: All specifications are subject to change without notice.
4.1 Physical
Environmental (enclosure): The device is only suitable for use in clean, dry areas.
Operating Temperature Range: 50 to 150 degrees C (122 to 302 degrees F)
Installation and mounting: Integrated and configured with the PGC5000 series Smart Ovens.
4.2 Power
Voltage:
Plasma reactor: 12V, 1.0 A
Total power consumption: <20 W
4.3 Modes of operation
Helium ionization mode (HID)
In this mode, the detector is sensitive to all organic and inorganic components except neon. Operating
in HID mode, sub ppm levels of fixed gases can be measured.
Argon ionization mode (AID)
In this mode, the detector is not sensitive to fixed gases and methane but is sensitive to a wide range
of organic and inorganic volatile components. It is capable of ionizing any component with an
ionization potential less than 11.5eV.
4.4 Detector sensitivity
Sensitivity is a function of the total application design. It depends on the mode of operation and the
ionization potential of the analyte. Sensitivity values are given with a 4:1 minimum signal to noise
ratio.
HID mode: Sensitive to fixed gases down to 0.5 nanograms using hydrogen as an indicator.
AID mode: Sensitive to benzene down to 20 picograms.
4.5 Gas consumption
Reaction gas flow:
HID mode: 80 to 100 ml/min
AID mode: 5 to 20 ml/min
Carrier gas flow:
Packed columns: 20 to 60 ml/min
Capillary columns: 5 to 30 ml/min
Utility specifications:
UHP (ultra-high purity) for all carrier and reaction gas supplies.
