GC 650 Gas Chromatography Equipment FID / TCD / TID / PDD , Detectors
GC650
5 kinds of sample injectors and all conventional detectors can be attachable depending on samples for analysis. In particular, for analysis of environmental samples (water quality, air, soil and wastes) satisfactory outcome can be achieved by connecting a sample preparation system such as the Purge & Trap.
Features of the GC650
- Automatic flow control and ignition of the FID-flame
- Auto-start of chromatogram when sample is injected
- Gas save function (Capillary Injector)
- TCD maximum current control based on the type of gas
- Optional valves (solenoid, 2-position) control function
- Automatic notification of power-off
Detectors: High selectivity and sensitivity
FID (Flame Ionization Detector)
- Improved sensitivity into 19mCoulomb/g Carbon
- Easy to disassemble and assemble detector
- Minimization of sample degeneration as well as jet pollution by means of inert quartz jet
- Auto ignition of hydrogen flame
- Use as TID by replacing a collector and bead
TCD (Thermal Conductivity Detector)
- High detection reproducibility by excellent temperature stability
- Supplying static current to 4 Rhenium-Tungsten filaments and selecting the optimal reactivity by changing the filament current by 2mA according to detector temperature.
TID (Thermionic Ionization Detector); NPD
- Selective reaction to phosphorous or nitrogen compounds like organic phosphorous pesticides
- TID Bead Current Auto Optimization: Automatic ignition as the optimal current supplied by sensing the bead condition of alkali Rb Salt.
- The induction of nitrogen/phosphorous is more 104 times than that of carbon
PDD (Pulsed Discharge Detector)
- ECD Mode: Analysis of organic chloric pesticides; MDQ-Pico (10-12 g) of Femto (10-15 g)
- HID Mode: Non-destructive Detector; Noble gas analysis/ FID substitute
- PDPID Mode
