为了防止含硫化合物发生吸附，分析低 ppm 级物质时需要对样品流路的不锈钢表面进行去活处理。本应用简报介绍了 Agilent 490 微型气相色谱仪与完全去活的进样口配合，对硫化氢和羰基硫的分离、低浓度检测和分析性能。

安捷伦开发出了一种使用气相色谱分析天然气与液化天然气中的永久性气体以及带 C6+基团的任意 C1-C6 扩展烃类的方法。气相色谱配置包括两个通道。第一个通道串联配置了液体和气体进样阀、分流进样口、配备了 HP-PLOT Q 和 Molsieve PLOT 毛细管柱的微板流路控制技术 (CFT) 中心切割，毛细管柱与单个热导检测器 (TCD) 连接。TCD 通道用于分析永久性气体与轻质烃。第二个通道串联配置了液体和气体进样阀、分流进样口、DB-1 色谱柱，色谱柱与火焰离子化检测器 (FID) 连接，用于分析扩展烃类。此外，FID通道具有反吹到检测器的 6 通阀，适用于无需分析扩展烃类并且需要缩短分析时间的复合 C6+ 基团分析。该配置采用毛细管柱，只需分析一次便可完成对天然气、液化天然气(NGL) 或液化石油气 (LPG) 中的永久性气体和扩展烃类的分析，此外还可用于相对简单的 C6+ 复合物分析。

Fossil fuels have been the main source of energy in industrial applications and transportation for decades. However, depleting reserves, environmental concerns and economic issues have led to the development of renewable, cheaper and cleaner alternatives. Bio-ethanol is one of those alternatives and is derived by fermenting the sugar and starch components of plant byproducts. Different purities of bio-ethanol are used as fuel sources. Hydrated ethanol fuel has not had treatment to remove moisture and contains between 93-96% ethanol. It is often used in flexible (flex-fuel) or dual fuel engines. Anhydrous ethanol has been treated to remove moisture and has a purity of at least 99%. It is blended at up to 25% v/v with gasoline. High purity fuel can be contaminated with elemental impurities during production, stockpiling and transportation, so accurate quantitation of metal content is important. According to ASTM D4806 specification [1] and the Brazilian National Agency of Petroleum, Natural Gas and Biofuels 2 (ANP) Resolution number 19/2015 [2], the presence of Cu, Fe, Na and S in ethanol must be controlled. Limit concentrations for Cu are 0.1 and 0.07 mg/kg (ASTM and ANP respectively), 5 mg/kg Fe (ANP), 2 mg/kg Na (ANP), and 30 mg/kg S (ASTM). In this study, the accuracy, precision and long term stability performance of the Agilent 5100 Synchronous Vertical Dual View (SVDV) ICP-OES was evaluated for the determination of Cu, Fe, Na and S in ethanol fuel samples according to ASTM D4806 and ANP Resolution 19/2015 methods.

A simple dilute-and-shoot procedure for determination of Cr, Ni, Pb and V in ethanol fuel by Microwave Plasma-Atomic Emission Spectrometry (MP-AES) is proposed. Samples were easily prepared and neither special nor expensive gases were needed for performing analyses. All limits of detection from 0.3–40 μg/L were compatible with the requirements taken into account when considering fuel impacts on environment and engine performance.
