control, the flow is adjustable between *0 to **0sccm and software
controls gas coefficient. High Temperature Furnace – The highest
temperature is ***0℃, and the stove heating rate can be
adjustable from 1℃/min to *0℃/min.
Air Refrigeration – Open (shell type) furnace can be quickly
cooling and optional refrigerator achieving rapid
refrigeration.
Optional Cryotrap – The temperature can be rising from
***0℃.
Temperature Control – Piping, steam generator. Stove and TCD
temperature all can be controlled by digit
Thermal Conductivity Cell Detector – *-arm rhenium tungsten
TCD has extremely high linear, accuracy, sensitivity and
stability.
Very small dead volume - Small volume valve and 3 mm pipe can
reduce dead volume, thus reduce the deviation of the peak.
Sample Support – U type pipe of large size can be convenient
for sample loading and cleaning, and can add powder, rod or shot
sample.
Sample Loading – Sample tube took down freely is convenient to
load samples.
Heating Pipeline – All the pipeline, valve and liquid
carburetor are heated to prevent condensation.
Safety – Independent furnace temperature thermal protection,
sealing pressure reducing valve, current circuit breaker, fuse, the
system design has timely security protection.
Software Features
The FINESORB****0 is controlled by powerful Windows R–based
operating software. It provides all the convenient features you are
accustomed to when using Windows-based programs. Point-and-click
operations, pull-down menus, access to multiple printers and
network drives, multitasking capability, and much more featured in
the FINESORB****0 user interface. Additionally, familiar Windows
format reduces the time required for training new operators, which
improve the efficiency more.
The principle diagram of each process visually displays on the
screen, so the status of each valve can be intuitively known.
The process of dynamic test shows the state of each
valve.
Show the value of each detector and sensor and display digital
quantity or curve according to the needs.
Display the setting parameter value in programming time,
convenient to compare with the measured value.
Visually display the state of each device, normal operation or
alarm state.
The carrier gas and reaction gas in the process of test, and
whether to use steam generator can all be controlled by software
program.
Purging time in test process can be controlled by
program.
The temperature of the stove can be heated in maximum *0
sections of program and can automatically save programming state.
The control module has the function of automatic correction and
learning with precision 0.*2℃.
The temperature of TCD thermal conductivity cell can be
programmed control, according to the need to set thermostatic
temperature, and can always maintain high precision constant
temperature with precision 0.*2℃.
The constant-current source by numerical control can be
programmed output, and can keep high precision constant-current
with precision 0.1%.
The temperature of steam generator also can be programmed
control, choose appropriate temperature according to the
evaporation temperature of liquid.
The temperature of condensation-preventing system in pipeline
and gas path also can be programmed control, make the equipment be
in normal use in bad environmental conditions.
lIn the process of test, the software can record
and display some important parameters. Sampling data will
automatically treat after the test.
It is able to process the
measured data into report and mark manually
The data can be imported to EXCEL or ORIGIN.
