Introduction GC-Pro FID
Teledyne Analytical Instruments 2
 Temperature measurements and control, 4-Channels
 6-Channel Dew point Hygrometer measurements, 6-
Channel
 Relay, (10) and solenoid outputs, (4)
 Alarm, (3) and over range indication outputs, (4)
 4-20mA current loop outputs, 10 channels
 HMI through Maple touch sensitive display
 The system operates at single phase AC, 110 or 220V 50/60
Hz.
 High resolution, accurate readings of concentration.
 Versatile analysis with three user-definable analysis ranges.
 Microprocessor based electronics: 8-bit CMOS
microprocessor with 32 kB RAM and 128 kB ROM.
 Auto ranging allows analyzer to automatically select the
proper preset range for a given measurement. Manual
override allows the user to lock onto a specific range of
interest.
 Two adjustable concentration alarms and a system failure
alarm.
 Extensive self-diagnostic testing at startup and on demand
with continuous power supply monitoring.
 RS-232 serial digital port for use with a computer or other
digital communication device.
 8-Analog outputs for concentration and range identification
(0-1 VDC standard and isolated 4-20 mA dc).
 Superior Accuracy
1.2 Principle of Operation
The analyzer uses a gas separation column to separate the
component of interest, for instance, benzene, from the other
hydrocarbons in the sample gas. Using a carrier gas and a
microprocessor actuated switching valve, the eluted gas is analyzed in
