Instrument technical index

Flexible Sample Introduction System

Up to three injectors may be installed and operated simultaneously with independent temperature control. Wide range of injectors is available to be chosen from for various applications. It is very convenient for installation and disassembly of sample injectors.

Sample Injector with Mono Packed Column/Double Packed Columns

Several alternative sample introduction methods, including on-column sample introduction and six-way valve injection;

Adapter for injection to capillary column (0.53 mm i.d.).

Sample injector for capillary column

Special sample injector with septum purge and back-pressure valve splitting;

Special programmable split/splitless injector with solenoid valve, septum purge, back-pressure valve splitting, and standalone carrier gas and make-up gas flow;

Modified dual-packed-column sample injector for injection to capillary column by employing some connectors and back-pressure valve splitting.

Advanced Pneumatics

Carrier gas control with constant pressure valve and constant flow valve;

Air and hydrogen control with constant pressure valve and needle valve;

Flow easily adjustable through constant flow valve and needle valve with digital display;

High precision, reproducibility and reliability.

Sensitive and reliable detector

Up to three detectors (FID, TCD, ECD, etc) may be installed and operated simultaneously. Simultaneous multi-detection with detectors in series or in parallel meets the various analysis requirements.

The new FID provides higher sensitivity than ever before. It is very convenient to disassemble and clean the jet and collector. Precisely fixed emitter configuration ensures conformity of product performance;

Excellent TCD detector with high-resistance tungsten-rhenium filaments provides high sensitivity. A sensitivity of 10000 mV·mL/mg is achieved with optional amplifier circuit board. Special configuration of air heat insulation enhances the stability of TCD detector

Constant-current, pulse-modulated ECD detector sets sensitivity and current by computer.


Advanced Microcomputer Control System

With advanced control techniques, microcomputer-based temperature control system provides superior performance.

High temperature precision (± 0.5), high reliability, and high resistance to disturbance;

Five independent heated zones, with maximum operating temperature of 400;

Temperature-limit setting and overheat protection.

Instrument control is accomplished through the keypad, and the instrument offers outstanding capabilities.


Power-off protection;

Ten methods saving and reloading

Two controls of external events;

Timing on/off of temperature control;

Timing program, detector status, measurement range, polarity and current setting and display;

Temperature setting values, actual values, retention time and analysis time display.


High-performance spacious column oven

Spacious column oven accommodating capillary column and dual packed columns and convenient for column installation;

Fast heat-up and rapid cool-down column oven with automated back-door opening (300 to 50 in 7 min);

Available for both near-ambient and above ambient temperature control;

Supports 5 oven ramps with 6 plateaus.
