More about Determinators...

-       Gas Analyser – consists of various gas lines for carrier, calibration and the pneumatic  lines, various combination of valves, Rotameters, Mass Flow Controllers and the high flow, high volume Thermal Conductivity Detector for H2/O2/N2/Xe/Kr detection.

-        High Temperature Electrode Furnace for fusion of the sample using a Graphite crucible. The sample is fused here and the liberated gases taken away for analysis to the TC Detector..

-        Electronic Control Circuitry consisting of  PLC’s with I/O modules and TCD, Micro controllers, High gain amplifiers, drift compensators, Relay modules and Timer Sequence programmer with RS 232 interface. The Analysers electronic unit controls all the operations from the front panel using the OP panel with large LCD display and membrane keypad for the determinator control.

-       Windows Based User friendly Integrating & Control Software

The system also incorporates the powerful PC which is connected to the Analyser via serial port for computation of the results.  The results are displayed on the video screen as well as printed on the printer. The specialized PC software includes many features which are customized to give a proper format of report as desired by the user.The complete control of the determinator is available via the PC optionally.

SAMPLE COMBUSTION SYSTEM (HIGH TEMPERATURE ELECTRODE FURNACE)


Sample materials are fused in graphite crucible using the powerful 7.5 KW Electrode Furnace (EF-2002-MT) for Hydrogen which achieves temperatures upto 2800° C and 15 KW Electrode Furnace for O2/N2/Xe/Kr (EF-2002-HT) which can achieve temperatures upto 3400° C. The Analysis take places using a combination of various techniques including Thermodynamics, High Temperature chemical kinematics & Chromatography techniques using a very high sensitivity Micro Thermal Conductivity Detector with special Nickel filaments. It determines the total gas content by fusion extraction using the EF-2002-MT or EF-2002-HT Electrode Furnace. The furnaces are capable to attain temperature approximately upto 2800° C by passing a current from 500A to 800A depending on the sample for the determination of H2 and 700A to 950A for samples for detemination of O2/N2/Xe/Kr. The plot of Temp. vs. electrode current is shown in the tabulation of the results also shown below.
