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 columnSpecial 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 PneumaticsCarrier 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 detectorUp 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 detectorConstant-current, pulse-modulated ECD detector sets sensitivity and current by computer.Company ProfileFAQ
