美國CIL標準品：

　　美國CIL穩(wěn)定性同位素世界上第一個生產(chǎn)穩(wěn)定性同位素(StableIsotope)標記化合物的生產(chǎn)商。20年來，CIL一直研究穩(wěn)定性同位素與穩(wěn)定性同位素標記化合物的開發(fā)、生產(chǎn)。主要標記性同位素有13C、12C、D、15N、18O和17O，目前已經(jīng)擁有8000多種標記化合物。
　　提交穩(wěn)定性同位素標記物質(zhì)可以被質(zhì)譜儀(MS)、氣相色譜-質(zhì)譜聯(lián)用儀、液相色譜-質(zhì)譜聯(lián)用儀、毛細管氣相色譜、核磁共振(NMR)等設備所探測、測量和監(jiān)控。
　　CIL的產(chǎn)品均能應用于不同的領域，如物理、化學、生物醫(yī)學、分析、診斷研究以及環(huán)境測試。
