APPARATUS AND METHOD FOR PRECISELY INJECTING TRACE AMOUNT OF LIQUID SAMPLE FOR PRODUCTION OF CERTIFIED REFERENCE MATERIAL (CRM) OF HYDROCARBON MIXTURE

摘要

The present invention relates to an apparatus and a method for precisely injecting trace amount of liquid sample for precise and uniform production of gaseous certified reference material (CRM). To this end, the apparatus comprises: a component gas supplying part (100) composed of a component gas cylinder (110), a needle valve (120) for regulating an amount of component gas to supply, a liquid transfer pump (130), and a cylinder rotation device (140); a regulating part (200) composed of a vacuum pump (210), a particle filter (200) for filtering out the component gas, a gas outlet (230), a gas injection part (240), and a weight measuring device (250); and a certified material cylinder (300) for mixing and storing the transferred component gas.;COPYRIGHT KIPO 2016
