　美國(guó)CEM公司是全球最大的微波化學(xué)儀器生產(chǎn)商，歷史上一直被稱(chēng)為微波技術(shù)創(chuàng)始者——Innovators in Microwave Technology。其銷(xiāo)售總額約占世界同類(lèi)市場(chǎng)的82%。
　　CEM設(shè)在北卡羅萊納州的科研機(jī)構(gòu)，是當(dāng)今世界上最大的微波化學(xué)研究實(shí)驗(yàn)基地，集中了世界一流的微波化學(xué)專(zhuān)家，不斷研究和探索微波化學(xué)機(jī)理，開(kāi)拓主頻2.45G-18GHz之間的微波技術(shù)科研應(yīng)用，取得了大量的成果和專(zhuān)利，歷史上由CEM專(zhuān)家推出的各種微波樣品處理方法，被權(quán)威機(jī)構(gòu)USEPA、AOAC、NCAT、ASTM等認(rèn)可作為通用標(biāo)準(zhǔn)方法，如USEPA3015/3051，UOP方法等。CEM共計(jì)擁有200余項(xiàng)技術(shù)專(zhuān)利應(yīng)用于微波化學(xué)，其新產(chǎn)品曾9次榮獲美國(guó)年度R&D100大獎(jiǎng)的殊榮。歷史上創(chuàng)造了：
　　第一臺(tái)微波消解系統(tǒng)；
　　第一臺(tái)微波水分含量測(cè)試系統(tǒng)；
　　第一臺(tái)微波干燥系統(tǒng)；
　　第一臺(tái)微波萃取系統(tǒng)；
　　第一臺(tái)微波灰化系統(tǒng)；
　　第一臺(tái)單模微波連續(xù)流動(dòng)有機(jī)合成系統(tǒng)。
　　現(xiàn)在幾乎所有著名的大型研究實(shí)驗(yàn)機(jī)構(gòu)都在使用CEM的微波產(chǎn)品。
　　CEM始終致力于技術(shù)和應(yīng)用開(kāi)發(fā)，近年來(lái)CEM積極參與微波藥物合成、微波陶瓷合成、微波納米材料合成、微波等離子體、微波金鋼石鍍膜等技術(shù)開(kāi)發(fā)，廣受學(xué)術(shù)界關(guān)注。特別是在精確控制AFC單模微波化學(xué)反應(yīng)/有機(jī)合成/藥物合成研究等方面都取得了重要的技術(shù)突破。
　　在安全上CEM一直精益求精，其微波裝置的設(shè)計(jì)符合所有現(xiàn)行的美國(guó)、加拿大、歐共體相關(guān)工業(yè)電器安全放射和防爆標(biāo)準(zhǔn)如：NRTL、ETL、UL、CE等。CEM儀器30年來(lái)從未發(fā)生過(guò)重大事故，CEM系列產(chǎn)品被公認(rèn)是世界上最安全的微波化學(xué)儀器，正在使用的CEM微波產(chǎn)品中，僅分析化學(xué)樣品前處理儀器就有四萬(wàn)多套。

CEM was established in 1978 by a chemist, an electrical engineer and a mechanical engineer, who designed and produced the first microwave laboratory instrumentation - a moisture/solids analyzer. The chemist, Michael J. Collins, had written his dissertation on microwave spectroscopy and felt certain that there was a market for microwave instrumentation that could produce rapid, accurate results. He was right. In the true spirit of an entrepreneurial inventor, Collins and his colleagues worked from a small building in Matthews, North Carolina, where they helped pioneer the field of microwave chemistry. Within a short time, CEM built a much larger manufacturing facility and began to pursue the international market. Today, the company has grown to include 4 international subsidiaries, a worldwide network of distributors and product lines that now encompass instrumentation for life sciences, analytical applications, and process control.

CEM Corporation, a private company based in Matthews, North Carolina, is the leading provider of microwave laboratory instrumentation. The Company has subsidiaries in the United Kingdom, Germany, Italy and France, as well as a global network of distributors. CEM designs and manufactures systems for life sciences, synthetic chemistry, analytical chemistry, and processing plants worldwide. The Company's products are used in many industries including pharmaceutical, biotech, chemical, environmental, and food processing, as well as for academic research.
