Gaschromatographie

Gas Chromatography GS-101A concentration offline analyzer Product Presentation: GS-101B Concentration offline analyzer is a special concentration offline chromatograph to analyze the trace quantity hydrocarbons composition in liquid oxygen, liquid air and exhaust inlet. It’s high separating degree, high sensitivity, to the material which is hard to separate ,it can directly test ethyne for 0.01ppm,and even test the ethyne for 0.001ppm after concentration ,which is necessary detect instrument to guarantee the air separating plant and the main condenser work safely .It’s widely used in air separation oxygenerator as it’s reliability and conveniently use. Function & Feature: it’s adopted two dimensions six-way valves to inject the samples .high precision in samples injection ,and good in repeatability.Possess concentration appliance and analyze column The detector is high sensitivity and low noise .high precision test (the lowest concentration of the ethyne is 0.001ppm),fast detect .long time work , it won’t be damaged under continuous work for one hundred thousand times. Tech Index: 1. temperature we use intelligent temperature controller to control the column compartment temperature ,hydrogen flame detector temperature .we can input all the sum toplimit of different controlled temperature on the keypad. It will warn and cut off power automatically no matter which temperature exceed the toplimit .The precision of temperature display is 0.1°C,the precision of controlling temperature is 0.3°C.setting range: room temperature 350°C. 2.The system steady time <1.5 hours 3.temperature controlled precision :±0.1°C 3.baseline drift: ≤1X10-11 A/30min 4.baseline noise: ≤1X10-12A 5.detected concentration :methane : ≥0.002ppm,ethane : ≥0.002ppm,ethene≥0.002ppm ,ethyne≥0.002ppm ,propane≥0.05ppm ,propylene≥0.01ppm , n-butane≥0.01ppm ,iso-butane≥0.01ppm,butadiene≥0.005ppm 6.product dimension : 52.5*38*38cm 7.N.W.:35KGS
