Project Description
Overviews
Fully automated PC controlled CHN analyzer for solid and liquid samples. The analyzer provides combustion of the sample followed by reduction, trapping, gas chromatographic separation and detection of the products by temperature stabilized thermal conductivity detector for C, H, N. The instrument has furnace for combustion with independent temperature control through software. Furnace temperature is maintained between 900-1100 0 C or more to ensure complete combustion. Ash finger, a standard part supplied with the instrument collects the ashes of the sample and can be taken out by using crucible tong. Analyzer has auto sampler with capacity of 60 samples. It has a mass flow controller/electronic flow controller for constant flow of carrier gas and sample introduce by ball valve technique for better accuracy of results to avoid the atmospheric nitrogen contamination.
