硫磺在我國的使用有著悠久的歷史，早在一千多年前我們的祖先就發(fā)明火藥。由于硫磺廣泛應(yīng)用于生成生活，包括硫磺礦、火山口、油井、磚窯、硫磺皂或膏、中藥材和火柴頭，化學(xué)性質(zhì)活潑，易燃并且產(chǎn)生大量氣體的特點(diǎn)。
浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司建立了氣相色譜法測定黑火藥中的硫磺,對萃取溶劑、進(jìn)樣口溫度和升溫程序進(jìn)行了優(yōu)化。分析條件為:以為萃取溶劑,進(jìn)樣口溫度240℃,柱溫程序:40℃保持1 min,以10℃/min升至80℃,保持2 min,再以10℃/min升至240℃,保持5 min。硫磺標(biāo)準(zhǔn)溶液在5～50μg/mL范圍內(nèi)線性關(guān)系良好,檢出限為0.65μg/mL,加標(biāo)回收率為92.4%～102.7%,相對標(biāo)準(zhǔn)偏差為1.4%,實(shí)現(xiàn)了黑火藥爆炸殘留物中硫磺的檢測。采用氣相色譜法對黑火藥中的硫磺進(jìn)行了定量分析,區(qū)分了不同的黑火藥樣品。

The use of sulfur in China has a long history, with our ancestors inventing gunpowder over a thousand years ago. Due to the widespread use of sulfur in daily life, including sulfur mines, volcanic craters, oil wells, brick kilns, sulfur soaps or ointments, traditional Chinese medicine, and match heads, it is chemically active, flammable, and produces a large amount of gas.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a gas chromatography method for the determination of sulfur in black powder, and optimized the extraction solvent, injection port temperature, and heating program. The analysis conditions are as follows: as the extraction solvent, the injection port temperature is 240 ℃, and the column temperature program is 40 ℃ for 1 minute, rising from 10 ℃/min to 80 ℃ for 2 minutes, and then rising from 10 ℃/min to 240 ℃ for 5 minutes. Sulfur standard solution between 5-50 μ Good linear relationship within the range of g/mL, with a detection limit of 0.65 μ G/mL, with a recovery rate of 92.4%~102.7% and a relative standard deviation of 1.4%, the detection of sulfur in the explosive residue of black powder has been achieved. Quantitative analysis of sulfur in black powder was conducted using gas chromatography, distinguishing different black powder samples.
