浩瀚车间空气中汽油的气相色谱测定玻璃微球柱HH-BLQ

汽油是无色或淡黄色、易燃、易挥发、略带臭味的液体。其中主要成分是脂肪族饱和烃及不饱和烃,还可能混有若干芳香烃及各种硫化物等杂质。车间空气中汽油的测定目前国。

浩瀚色谱（山东）应用技术开发有限公司建立工作场所空气中溶剂汽油测定的新方法。方法:利用玻璃球柱,直接进样-气相色谱法测定工作场所空气中的溶剂汽油。结果:在测定条件下,可用以正己烷计来测定空气中溶剂汽油,方法测定范围为2.5⁸00 mg/m3,相关系数大于0.999,检出限为1×10-3μg,回收率为94%⁹6%,RSD2.6%⁵.2%。结论:该方法准确度较高,操作简便,样品测定结果满意。

规格：2m*4mm   Gasoline is a colorless or light yellow, flammable, volatile, slightly odorous liquid. The main components are aliphatic saturated hydrocarbons and unsaturated hydrocarbons, and some aromatic hydrocarbons and various sulfides and other impurities may also be mixed. Determination of gasoline in workshop air current state.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established a new method for the determination of solvent gasoline in workplace air. Methods: The direct injection-gas chromatography method was used to determine the solvent gasoline in the air of the workplace by using a glass ball column. Results: Under the determination conditions, the solvent gasoline in the air can be measured by n-hexane, the determination range of the method is 2.5800 mg/m3, the correlation coefficient is greater than 0.999, the detection limit is 1×10-3μg, and the recovery rate is 94%96% , RSD2.6%5.2%. Conclusion: The method has high accuracy, simple operation, and satisfactory sample determination results.
