汽油中芳烃，通常采用采用三柱一阀二维/多维气相色谱系统单次进样、归一化法定量分析初馏200℃的汽油(包括含有醇类、醚类的成品汽油)中的芳烃含量。具体操作:样品进入系统后分为两路,一路经过分析柱1(Col 2)后直接到检测器;另一路进入预切柱(Col 1),烷烃和烯烃先于芳烃流出,待烷烃和烯烃放空后将阀切换到反吹状态,Col 1中的芳烃被反吹出来,进入分析柱2(Col 3),经过分离后到检测器,经计算得到样品分析结果。此法操作复杂，费时费力，仪器需要二维/多维色谱，价格昂贵，一般企业很难配置.
滕州市浩瀚色谱仪器技术服务有限公司，，研发专用毛细管柱，直接进样测定汽油中芳烃含量，外标定量，结果满意，实用性强，值得推广。该法简便、快速、样品用量少、测试范围宽,避免了汽油中其他组分对芳烃测定的干扰。

Determination of Monomeric Aromatic Hydrocarbons in Gasoline Fractions by Gas Chromatography

Stationary phase: dedicated
Specification: 30m*0.25mm*0.25um
Model: HH-AH


Aromatic hydrocarbons in gasoline are usually used in a single injection and normalization method using a three-column one-valve two-dimensional/multi-dimensional gas chromatography system to quantitatively analyze gasoline (including finished gasoline containing alcohols and ethers) which is initially distilled to 200 °C. Aromatic content. Specific operation: After the sample enters the system, it is divided into two ways, one pass through the analytical column 1 (Col 2) and directly to the detector; the other enters the pre-cut column (Col 1), the alkane and olefin flow out before the aromatic hydrocarbon, and the alkane and olefin After venting, the valve is switched to the backflushing state, and the aromatic hydrocarbons in Col 1 are back-blown out, entering the analytical column 2 (Col 3), and after separation, the detector is obtained, and the sample analysis result is calculated. This method is complicated, time-consuming and laborious. The instrument needs 2D/multi-dimensional chromatography, which is expensive and difficult for general enterprises to configure.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. keeps pace with the times, researches and develops special capillary columns, and directly measures the content of aromatic hydrocarbons in gasoline. The external standard is quantitative, the results are satisfactory, the practicability is strong, and it is worth promoting. The method is simple, rapid, the sample dosage is small, and the test range is wide, which avoids the interference of other components in the gasoline on the determination of aromatic hydrocarbons.
