Description
technical field:
The utility model relates to a kind of infrared carbon sulfur analyzer carbon monoxide absorption cell, belongs to Gas Thickness Detecting Technology field.
background technology:
Infrared carbon sulfur analyzer is mainly used in carbon in the materials such as the ferrous metal in the industries such as metallurgy, machinery, commodity inspection, scientific research, chemical industry, coloured genus, rare earth metal inorganics, ore, pottery, sulfur content analysis.The infrared carbon sulfur analyzer of analytical instrument adopts high-frequency induction furnace burning sample, carbon sulphur two element massfraction in infrared absorption test sample.Have that measurement range is wide, antijamming capability is strong, multiple functional, simple to operate, the analysis result feature such as quick and precisely.
Carbon in infrared carbon sulfur analyzer sample, the sulphur high-temperature heating under excess oxygen, is oxidized to carbon dioxide, sulfur dioxide gas.This gas enters corresponding absorption cell after treatment, absorbs corresponding infrared radiation, and being forwarded by detector is signal, machine process Output rusults as calculated.The method has accurate, quick, highly sensitive feature, and high-low carbon sulfur content all uses, and adopt the infrared carbon sulfur analyzer of the method, automaticity is higher, is applicable to the occasion that analysis precision requirement is higher.
Infrared carbon sulfur analyzer is, by the method for burning, sample is led to oxygen burning, produces CO2, SO2 gas, finally according to the difference of CO2 and SO2 wavelength, detect the gas concentration of CO2 and SO2 respectively, then according to molecular weight, software calculates the percentage composition of carbon and sulphur automatically.But in combustion, the sample that particularly carbon content is high, due to the too high levels of carbon, in combustion can because of failing Thorough combustion, and produce a small amount of CO gas, and instrument can only detect the concentration of CO2, the concentration of CO gas cannot be detected, the on the low side of analysis result can be caused like this.
utility model content:
For the problems referred to above, the utility model provides a kind of infrared carbon sulfur analyzer carbon monoxide absorption cell.
A kind of infrared carbon sulfur analyzer carbon monoxide absorption cell of the present utility model, it comprises CO absorption cell, infrared window, chopper, modulating motor, infrared light supply, optical filter, amplification board and infrared eye; The two ends of CO absorption cell are provided with infrared window, the side of one end infrared window is connected with chopper, the side of chopper is provided with infrared light supply, chopper is connected with modulating motor, the arranged outside of other end infrared window has optical filter, the outside of optical filter is connected with amplification board, and amplification board is provided with infrared eye.
As preferably, described optical filter is CO optical filter.
The beneficial effects of the utility model are: it can detect the concentration of CO in sample, can be good at the problem solving high-carbon sample analysis unstable result, Lower result, thus improve accuracy and the precision of instrument.Be provided with infrared window at the two ends of CO absorption cell, arranging of infrared window can increase the induction of absorption cell to source light, thus improves the absorption efficiency of absorption cell.
