HH-WAX毛细管柱 航空涡轮燃料中脂肪酸甲酯测定的详细资料
航空涡轮燃料中脂肪酸甲酯测定
航空涡轮燃料中脂肪酸甲酯测定 详细信息:
名称:毛细管柱
固定液:键合聚乙二醇
规格:60m*0.20mm*0.40um
型号:HH-WAX
应用:航空涡轮燃料中脂肪酸甲酯含量的测定 气相色谱-质谱法
柱效高,分离好,脂肪酸得到有效分离
本标准规定了采用气相色谱-质谱法定性和定量测定航空涡轮燃料中脂肪酸甲酯的试验方法。
本标准适用于测定航空涡轮燃料中来源于生物柴油的多种脂肪酸甲酯(见表1),总脂肪酸甲酯的含量测定范围为4.5 mg/kg~140 mg/kg。
注1: 航空涡轮燃料(以及受柴油或生物柴油污染的航空涡轮燃料)中可能含有一些相对分子质量较高的烃类组分,这些组分会掩盖微量脂肪酸甲酯的出峰。低碳数的脂肪酸甲酯,例如椰子油中得到的脂肪酸甲酯,会受到航空涡轮燃料中部分重组分的干扰,在含量较低时无法进行定量测定。

Determination of fatty acid methyl ester in aviation turbine fuel
Determination of fatty acid methyl ester in aviation turbine fuel Details:
Name: Capillary column
Fixative: Bo
nded polyethylene glycol
Specifications: 60m*0.20mm*0.40um
Model: HH-WAX
Application: Determination of fatty acid methyl ester co
ntent in aviation turbine fuel gas chromatography-mass spectrometry
High column efficiency, good separation, effective separation of fatty acids
This standard specifies the test method for the legal and quantitative determination of fatty acid methyl esters in aviation turbine fuel by gas chromatography-mass spectrometry.
This standard is applicable to the determination of various fatty acid methyl esters derived from biodiesel in aviation turbine fuels (see Table 1). The co
ntent of total fatty acid methyl esters is determined in the range of 4.5 mg/kg to 140 mg/kg.
Note 1: Aviation turbine fuels (and aviation turbine fuels co
ntaminated with diesel or biodiesel) may co
ntain some relatively high molecular weight hydrocarbon components, which may mask trace peaks of fatty acid methyl esters. Fatty acid methyl esters with a low carbon number, such as those obtained from coco
nut oil, will be disturbed by some of the heavy compo
nents in aviation turbine fuels and cannot be quantitatively determined at low levels.
