Instrument technical index
1. 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
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
2. Advanced Pneumatics
Carrier gas control with constant pressure valve and constant flow
Air and hydrogen control with constant pressure valve and needle
Flow easily adjustable through constant flow valve and needle valve
with digital display;
High precision, reproducibility and reliability.
3. 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
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
Constant-current, pulse-modulated ECD detector sets sensitivity and
current by computer.
4. Advanced Microcomputer Control System
With advanced control techniques, microcomputer-based temperature
control system provides superior performance.
High temperature precision (¡À 0.5¡ãC), high reliability, and high
resistance to disturbance;
Five independent heated zones, with maximum operating temperature of
Temperature-limit setting and overheat protection.
Instrument control is accomplished through the keypad, and the
instrument offers outstanding capabilities.
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.
5. 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¡ãC to 50¡ãC in 7 min);
Available for both near-ambient and above ambient temperature
