NOTE. After the silica gel adsorption material can be extracted with n-hexane (SGT-HEM) which may be n-hexane extractable material (HEM) the components, but can not be absorbed by the silica gel Attached, is the non-polar material (NPM). A. 1.2 "substance can be extracted with n-hexane" description of the provisions of this appendix applicable to the determination not only oil, but also can be applied to other Hexane extraction of the test substance. Similarly, the "silica gel adsorption of n-hexane can be extracted material" means specified in appendix also used this party Method can not be measured can be adsorbed on silica gel substance n-hexane (non-polar material) Consistent. Note. material (HEM) is n-hexane extraction key from a sample of this material was measured by the method (oil), including non-volatile hydrocarbons, Vegetable oils, animal fats, paraffin, soap, grease and other related substances. A. 1.3 The method can not be used for the determination of volatile substance is below 85 ℃. Petroleum fuels in the solvent distillation process, from gasoline to No. 2 Fuel will be some loss. A. 1.4 part of component content higher crude oil and heavy fuel oil is not soluble in hexane, if measured using this method, the recovery rate is low. A. 1.5 Method for the determination of HEM and SGT-HEM content ranging from 5mg/L ~ 1000mg L samples/sample reduction if Dosage, higher levels of samples can HEM and SGT-HEM determination. A. 1.6 The method of HEM and SGT-HEM method detection limit (MDL) of 1.4mg/L, the limit of quantification of 5.0mg/L. Note 1. The method detection limit (MDL) is the lowest analyte concentration of the analyte concentration is greater than 0, at 99% confidence level that can be detected. Note 2. The lower limit of quantification (ML) is the smallest identifiable signal analysis system can give the analytes and the standard concentration values acceptable, corresponds to the lowest calibration standards concentration.

A. 2 Summary of Method A. 2.1 1L sample was acidified to a pH less than 2, with n-hexane in a separatory funnel and extracted three times in a row, the extract was dried over sodium sulfate. A. 2.2 distilling off the solvent from the extract, dehydrated and weighed to determine the content of HEM. If the determination of SGT-HEM, HEM will again It was dissolved in n-hexane. A. 2.3 Determination of SGT-HEM, HEM will be a certain percentage of the amount of silica gel was added to n-hexane and then dissolved after the HEM, To remove polar substances. Filtered to remove silica gel, solvent was distilled off, dehydrated and weighed to determine the content of SGT-HEM. A. 2.4 pairs of experimental system extraction, distillation, and gravimetric calibration and testing. A. 3 Description HEM and SGT-HEM are in analyte method definition, namely the definition of HEM and SGT-HEM are depending upon the test methods. Samples of oil and/or lipid characteristics and non-oily substance can be extracted, the measurement results will have an impact.
