Main feature

(A) three protection

1) Over-temperature protection: When the maximum value of the actual temperatures of the hot zone exceeds the set overtemperature protection device automatically turns off the instrument each heating zone power, while the alarm in order to avoid accidents.
2) over-current protection: When working at TCD detector, such as current set too high or TCD sudden increase in resistance, overcurrent protection device automatically turns off the TCD bridge current, and alarm and display OVER TCD to protect the tungsten being burned (if the user due to operational errors, start TCD in the absence of carrier gas, the device can automatically cut off power to protect the tungsten filament). Also increase the amplification circuit, in order to increase sensitivity.
3) crash protection: instrument at work, when a short circuit occurs thermal element heating zone, when the circuit, the heating wire on the ground, the computer operating system crashes and so on, the instrument can automatically cut off power and alarm, to avoid further work accidents . The above three points protection feature allows you to analyze more safe and secure work.

(B) six Thermostat

(C) pneumatic control


Pneumatic controller with external capillary gas line box, gas assist gas manifold box placed separately, air ratio adjustment intuitive, flexible control, and once a manifold problems can instantly switch had no effect on the host operating, maintenance Convenience.


(Iv) noise


Hosts in each blade using a mold forming, symmetry, avoid imbalance generated noise during operation.


(E) flexible configuration


Capillary injector independent, you can configure dual capillary injector according to user requirements of the dual amplifier board to install two capillary column; you can also install two packed column; you can also install a packed column and a capillary column; also can increase the flexibility TCD, FPD, NPD, ECD detector based on this analysis to meet different requirements; an instrument can install up to three injectors and three detectors.


(Vi) appearance


With a vertical oven, nice shape, and small footprint, suitable for laboratory use small space, the new back-pressure valve using a split / splitless mode.


(Vii) pneumatic controller


Pneumatic controller with external, single or dual capillary gas line box, single or dual carrier gas path box, single or dual gas assisting gas manifold box placed separately, air ratio adjustment intuitive, flexible control, you can select the most appropriate combination of flow controller based on an analysis purposes.


(Viii) monitor / keyboard


GC1690 display information-rich, simple keyboard, bright backlit LCD display for easy reading, easy to understand Chinese keyboard, reducing the burden on the operator. Green button for the temperature control series; blue button for the detector parameter control series; the white keys of the numeric keys series; black keys to control external events series.


(Ix) detector (DET)


Can be installed at the same time in any three of the following detectors:
FID flame ionization detector
TCD thermal conductivity detector
FPD flame photometric detector
NPD NPD
ECD electron capture detector


(X) injector


1) packed column on column
2) Split / splitter no injection
3) large-diameter capillary WBC injection
4) packed column steam sample
5) The six-way valve gas into style


(Xi) Oven


Use get recognized high performance column oven large gasification chamber considering the heat radiation generated by heating or detector, column compartment is designed to erect the structure, the maximum temperature can reach 420 ℃, temperature range + 7 ℃ ~ 420 ℃, 5 stage temperature programming, automatic back door, you can set the height of the temperature within 420 ℃, 450 ℃ fixed independent protection circuit, with dual protection structure.
