| Instrument technical index | |
| 1. | Flexample 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. | |
| 2. | 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. | |
| 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 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. | |
| 4. | Advanced Microcomputer Control System |
| * With advanced control techniques, microcomputer-based temperature control system provides superior performance; * High temperature precision (± 0.5ºC), high reliability, and high resistance to disturbance; * Five independent heated zones, with maximum operating temperature of 400ºC; * Temperature-limit setting and overheat protection; * Instrument control is accomplished through the keypad, and the instrument offers outstanding capabilities. * Self-diagnosis; * 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. | |
| 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 (300ºC to 50ºC in 7 min); * Available for both near-ambient and above ambient temperature control; * Supports 5 oven ramps with 6 plateaus. | |
