9、thdrawn 2009)33.Summary of Test Method3.1 A representative specimen is introduced into a gas-chromatographic column.The methyl ethyl ketone is separatedfrom other impurities such as hydrocarbons,alcohols,acetone,di-sec-butyl ether,and ethyl acetate as the components aretransported through the column
10、 by an inert carrier gas.Theseparated components are measured in the effluent by adetector and recorded as a chromatogram.The chromatogramis interpreted by applying component-attenuation and detector-response factors to the peak areas,and the relative concentra-tion is determined by relating individ
11、ual peak response to thetotal peak response.Water,acidity,and nonvolatiles are mea-sured by the procedures listed in 3.2,and the results are usedto normalize the results obtained by gas chromatography.3.2 The appropriate ASTM test methods are:3.2.1 WaterTest Method D1364.3.2.2 AcidityTest Method D16
