HH-WAX毛细管柱 GC法测定汽车香水中甲醇的含量

名称：石英毛细管柱

固定相：键合/交联聚乙二醇

规格：60m*0.25mm*0.25um

型号：HH-WAX

        为建立GC法测定不同品牌汽车香水中甲醇的含量,浩瀚色谱（山东）应用技术开发有限公司采用毛细色谱柱HH-WAX(60 m×0.25mm,0.25μm),采用程序升温,即初始温度70℃,保持2min,以5℃/min的速率升温120℃,保持2 min,用FID检测器测定甲醇的含量.结果显示,甲醇进样量在0.08-1.0mg/m L内线性关系良好(R=0.998,n=6),平均加样回收率为99.3%,RSD=1.2%(n=9).这表明该方法操作简单快速,灵敏度高,专属性强,可直接用于汽车香水中甲醇的测定.

Name: Quartz Capillary Column

Stationary Phase: Bonded/Cross-linked Polyethylene Glycol

Specifications: 60m*0.25mm*0.25um

Model: HH-WAX

         In order to establish a GC method for the determination of methanol content in different brands of car perfumes, Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used a capillary column HH-WAX (60 m×0.25 mm, 0.25 μm), and a programmed temperature was adopted, that is, the initial temperature was 70 °C. ℃, maintained for 2 min, heated to 120 ℃ at a rate of 5 ℃/min, maintained for 2 min, and measured the content of methanol with a FID detector. The results showed that the methanol injection volume had a good linear relationship within the range of 0.08-1.0 mg/mL ( R = 0.998, n = 6), the average sample recovery was 99.3%, RSD = 1.2% (n = 9). This shows that the method is simple and fast, high sensitivity and specificity, and can be directly used in car perfume Determination of methanol.
