Chromatograph temperature controller NeoCHROM BZT-1
designed to replace outdated temperature regulators of gas chromatographs. Often such modernization is simply necessary to work with capillary columns- detector, injector and oven temperature regulation
- detector, injector and oven temperature monitoring
- programming of the heating rate of the thermostat during the analysis
- storage of up to 16 programs in non-volatile memory
- programming of up to 20 isothermal steps during analysis
- control of the solenoid valve in the split vent line for split/splitless operation
Opportunities:
- The block is implemented on semiconductor elements and controlled by a microcontroller
- The controller programs, monitors and controls three temperature channels (detector, injector and oven), with an accuracy of 0.1 °C and a setpoint increment of 1 °C, and controls the vent valve in the carrier gas line.
- Supply voltage 220V+10%. The switching voltage for each temperature channel is 220V
- Switched load power, detector channel: up to 500 W
- Switched load power, injector channel: up to 500 W
- Switched load power, oven channel: up to 4000 W

System components and scope of supply
The unit structurally consists of two sub-units: a control unit and a power unit.
- The block consists of a software and hardware part. The program is located in the ROM located on the controller board
- The program functionally consists of the temperature channel control algorithm, the temperature measurement algorithm for each channel, the keyboard and indicator processing algorithm, the analysis formation and processing algorithm.
- The control unit is a rectangular plastic housing with an LCD indicator, four LEDs and four buttons on the front panel, on the back panel of the indicator there is a connector that connects the control unit and the power unit. The power unit is a plate on which the following are placed: a transformer, four high-voltage switching elements, a temperature sensor, and connectors. The power unit is installed inside the chromatograph.
- During modernization, it is possible to place both blocks in the analytical block of the chromatograph
