1.1 This test method covers the quantitative determination of saturates, olefins, aromatics, and oxygenates in sparkignition engine fuels by multidimensional gas chromatography. Each hydrocarbon type can be reported either by carbon number (see Note 1) or as a total. NOTE 1—There can be an overlap between the C9 and C10 aromatics; however, the total is accurate. Isopropyl benzene is resolved from the C8 aromatics and is included with the other C9 aromatics. 1.2 This test method is not intended to determine individual hydrocarbon components except benzene and toluene. 1.3 This test method is divided into two parts, Part A and Part B. 1.3.1 Part A is applicable to the concentration ranges for which precision (Table 10 and Table 11) has been obtained: Property Units Applicable range Total aromatics Volume % 19.32 to 46.29 Total saturates Volume % 26.85 to 79.31 Total olefins Volume % 0.40 to 26.85 Oxygenates Volume % 0.61 to 9.85 Oxygen Content Mass % 2.01 to 12.32 Benzene Volume % 0.38 to 1.98 Toluene Volume % 5.85 to 31.65 Methanol Volume % 1.05 to 16.96 Ethanol Volume % 0.50 to 17.86 MTBE Volume % 0.99 to 15.70 ETBE Volume % 0.99 to 15.49 TAME Volume % 0.99 to 5.92 TAEE Volume % 0.98 to 15.59 1.3.1.1 This test method is specifically developed for the analysis of automotive motor gasoline that contains oxygenates, but it also applies to other hydrocarbon streams having similar boiling ranges, such as naphthas and reformates. 1.3.2 Part B describes the procedure for the analysis of oxygenated groups (ethanol, methanol, ethers, C3 to C5 alcohols) in ethanol fuels containing an ethanol volume fraction between 50 % and 85 % (17 % to 29 % oxygen). The gasoline is diluted with an oxygenate-free component to lower the ethanol content to a value below 20 % before the analysis by GC. The diluting solvent should not be considered in the integration, this makes it possible to report the results of the undiluted sample after normalization to 100 %. 1.4 Oxygenates as specified in Test Method D4815 have been verified not to interfere with hydrocarbons. Within the round robin sample set, the following oxygenates have been tested: MTBE, ethanol, ETBE, TAME, iso-propanol, isobutanol, tert-butanol and methanol. Applicability of this test method has also been verified for the determination of n-propanol, acetone, and di-isopropyl ether (DIPE). However, no precision data have been determined for these compounds. 1.4.1 Other oxygenates can be determined and quantified using Test Method D4815 or D5599. 1.5 The method is harmonized with ISO 22854. 1.6 This test method includes a relative bias section for U.S. EPA spark-ignition engine fuel regulations for total olefins reporting based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D1319 as a possible Test Method D6839 alternative to Test Method D1319. The Practice D6708 derived correlation equation is only applicable for fuels in the total olefins concentration range from 0.2 % to 18.2 % by volume as measured by Test Method D6839. The applicable Test Method D1319 range for total olefins is from 0.6 % to 20.6 % by volume as reported by Test Method D1319. 1.7 This test method includes a relative bias section for reporting benzene based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D3606 (Procedure B) as a possible Test Method D6839 alternative to Test Method D3606 (Procedure B). The Practice D6708 derived correlation equation is only applicable for fuels in the benzene concentration range from 0.52 % to 1.67 % by volume as measured by Test Method D6839. 1.8 This test method includes a relative bias section for reporting benzene based on Practice D6708 accuracy assessment between Test Method D6839 and Test Method D5580 as a possible Test Method D6839 alternative to Test Method 1 This test method is under the jurisdiction of ASTM Committee D02 on Petroleum Products, Liquid Fuels, and Lubricants and is the direct responsibility of Subcommittee D02.04.0L on Gas Chromatography Methods.

This document gives guidance on methods of handling, mounting and surface treatment for a biomaterial specimen prior to surface chemical analysis. It is intended for the analyst as an aid in understanding the specialized specimen-handling conditions required for analyses by the following techniques: — X-ray photoelectron spectroscopy (XPS or ESCA); — secondary ion mass spectrometry (SIMS); — Auger electron spectroscopy (AES). The protocols presented are also applicable to other analytical techniques that are sensitive to surface composition, such as: — attenuated total reflectance -Fourier transform infrared spectroscopy (ATR-FTIR); — total reflection X-ray fluorescence (TXRF); — ultraviolet photoelectron spectroscopy (UPS). The influence of vacuum conditions applied and the issue of contamination before and after analysis and implantation, as well as issues related to contamination during analysis, are addressed. Biomaterials covered here are hard and soft specimens such as metals, ceramics, scaffolds and polymers. This document does not cover such viable biological materials as cells, tissues and living organisms. Other related topics not covered in this document include: preparation of specimens for electron or light microscopy.

6.3 具塞滴定管的润滑及试漏 6.3.1 涂润滑剂:将滴定管平放,取下旋塞,擦干旋塞和旋塞槽,取少量凡士林(或硅脂),在旋塞孔的细口端(不超过流液孔)及旋塞的粗端(不超过流液孔)沿圆周均匀涂布。将旋塞插入旋塞孔,向同一方向旋转,从外面观察旋塞和旋塞槽整体透明,转动灵活。用橡皮筋固定旋塞。如出现润滑剂堵塞流液孔,可将旋塞及滴定管下端放入热水中使润滑剂融化流出,然后重新涂布。 6.3.2 试漏:用水充满滴定管并将液面调至“0”刻度线,将滴定管夹持在滴定管架上静置约2min,用干燥洁净滤纸检查滴定管下端及旋塞两端不应有液体渗出,观察液面无下降。将活塞旋转180°,再静置约2min再次检查。若漏液,应重新涂润滑剂。 6.4 无塞滴定管的试漏 6.4.1 检查乳胶管是否老化,玻璃珠大小是否合适。 6.4.2 试漏:用水充满滴定管并调至“0”刻度线,将滴定管直立夹持在滴定管架上静置5min。观察液面无下降,滴定管下端无渗出。若有漏水应更换橡皮管或管内玻璃珠,直至不漏水且能灵活控制液滴为止。
