【摘要】:建立聚二氧環(huán)己酮原料中單體二氧環(huán)己酮?dú)埩袅康臍庀嗌V測(cè)試方法。采用DB-624毛細(xì)管色譜柱(30.0 m×535μm×3.00μm),程序升溫(146℃保持5 min,30℃/min升溫至200℃,保持2 min)。載氣為氮?dú)?氫火焰離子化檢測(cè)器(FID),進(jìn)樣口溫度240℃,檢測(cè)器溫度250℃,分流比5:1,進(jìn)樣量2μL。結(jié)果顯示單體在0.0239~0.1794 mg/m L范圍內(nèi)線性關(guān)系良好,平均回收率為100.3%,RSD為1.39,檢測(cè)限濃度為0.2μg/m L,定量限濃度為0.5μg/m L。該方法簡(jiǎn)便快捷、準(zhǔn)確度和靈敏度高。
