EEU Specification for GC (Gas Chromatograph)
Reference Specification for test setup having GC (Gas Chromatograph) with HEAD SPACE AUTO SAMPLER to carry out Dissolved Gas Analysis of insulating oils as per International Standard ASTM-3612-02 Method - C
Software
There shall be software to control and monitor all functions of GC and Auto sampler with facility to carry out complete setting of parameters through software itself, monitor all the system components in real time and give a visual indication. It shall be possible to programme run-time events like, temperature programming, carrier gas/fuel gas flow settings, time programming, valve operating, data acquisition etc. It shall have facility to configure, store, recall and run analytical methods, which shall hold comprehensive information like event programming, detector configuration, integrator programming, calibration tables etc to carry out complete analysis automatically. The Software shall be common MS-Windows-7/XP/ 2000 / NT based user friendly, menu driven GUI type. It also should have:
Reference Specification for GC with auto headspace sampler

Data Acquisition, Analysis and Storage: The software shall be capable of acquiring the run- data from all the detectors and storing it in raw form on the hard disk. It shall have following features:
a) Automatic and manual Integration with various integration functions
b) Custom Report generation with chromatograms, spectrum analysis data printouts etc

Calibration curves: Software shall have facility to accept, store and apply multi-point calibration curves for concentrations with various curve-fitting techniques for standard gas concentrations.

Instrument Calibration and Validation: The software shall have facility to carry out validate and calibrate the instrument against certified standards and apply appropriate correction factor.

Other features: It is desirable that the software has additional features like setting up methods, early maintenance feedback, database for organizing, storing and retrieving chromatographic data etc.

Software Validation: The software shall be fully validated. Relevant certificates of software validation shall be supplied. This software validation shall also be carried out during AMC every year.
