The Performance Characteristics
1. The third order process is heating up, which can satisfy the
analysis demand of the multi-component of the sample.
1) main control circuit adopts new integrated digital electronic
circuit, temperature control precision of 0.01 ℃, the performance
is more stable;
2) temperature programmed: 13 order, heating rate 0 to 50 ℃ / min.
The incremental 0.1 ℃ / min;
2. The design of the column box is further improved to facilitate
the rapid cooling of the instrument.
1) the volume is large, and it is the intelligent rear door opening
system, which reduces the stable balance time of the system after
the program rise/cooling system;
2) system of heating furnace temperature range is + 7 ℃ ~ 400 ℃;
3) the user can recalibrate the furnace temperature and set the
maximum temperature and temperature balance time of the heating
furnace.
3. Unique and selective enhancement of the sample system.
1) unique sample entrance design solves the sample discrimination;
2) two sampling systems can be installed at the same time: filled
column, capillary diverter/non-shunt injection system (with
diaphragm cleaning function);
3) optional automatic/manual gas six - pass injection valve
sampler, headspace injector, heat analyser, pyrolysis furnace,
methanol converter.
4) double column compensation work can not only solve the program
drift caused by heating, but also reduce the influence of
background noise, and can get lower minimum detection limit.
4. The instrument operation interface is simple and easy to learn,
with complete functions and a more humanized design.
1) the instrument adopts large-screen LCD screen, which is
intuitive and easy to operate;
2) it has the function of starting up self-diagnosis;
3) stopwatch function (convenient flow measurement) and operation
timer function;
4) power failure storage protection function;
5) keyboard locking function.
5. Good stability, high sensitivity and multiple detectors.
1) which can be installed at the same time two kinds of the same or
different detector: hydrogen flame ionization detector (FID), the
thermal conductivity detector (TCD), electron capture detector
(ECD), nitrogen and phosphorus detector (NPD), flame photometric
detector (FPD), etc.
2) hydrogen flame ionization detector is easy to be disassembled
and installed for easy cleaning or replacement of nozzle;
3) high detection sensitivity of high resistance single column
thermal conductivity detector, stable baseline stability (stable in
15 minutes);
4) input signals can be used for logarithmic amplification, reduce
interference and improve sensitivity.
