美國(guó)CIL標(biāo)準(zhǔn)品：

　　美國(guó)CIL穩(wěn)定性同位素世界上第一個(gè)生產(chǎn)穩(wěn)定性同位素(StableIsotope)標(biāo)記化合物的生產(chǎn)商。20年來(lái)，CIL一直研究穩(wěn)定性同位素與穩(wěn)定性同位素標(biāo)記化合物的開(kāi)發(fā)、生產(chǎn)。主要標(biāo)記性同位素有13C、12C、D、15N、18O和17O，目前已經(jīng)擁有8000多種標(biāo)記化合物。
　　提交穩(wěn)定性同位素標(biāo)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(xì)管氣相色譜、核磁共振(NMR)等設(shè)備所探測(cè)、測(cè)量和監(jiān)控。
　　CIL的產(chǎn)品均能應(yīng)用于不同的領(lǐng)域，如物理、化學(xué)、生物醫(yī)學(xué)、分析、診斷研究以及環(huán)境測(cè)試。

      Cambridge Isotope Laboratories, Inc. (CIL) is the world's premier producer of stable isotope labeled compounds and the world leader in the field of isotope separations with an annual production capacity of 120 kilograms of Carbon-13 and annual production capacity of 250 kilograms of Oxygen-18. For more than 20 years, CIL has specialized in the development, production, and marketing of stable (non-radioactive) isotopes and chemical compounds labeled with stable isotopes. With an inventory of over 8000 products, CIL has the most complete product offering of stable isotope labeled compounds available.

CIL employs 130 people at its state-of-the-art 57,000 square foot Andover, Massachusetts production laboratories and its Xenia, Ohio isotope separation facility. CIL's chemists are experts in their fields, with extensive years of experience exclusively in the synthesis of stable isotope labeled compounds.
