 With the increasingly close combination of modern science and technology and industry, institutions of higher learning and key laboratory as the feature of advanced productivity incubators he become more and more obvious, laboratories and universities specialized in combination with the people's livelihood industry, promote the separation of complex samples by chromatographic instrument ysis and the rapid development of purification equipment, all kinds of new, more applicable chromatographic techniques and instruments.However, separation science and the market including technology not only has a high performance liquid chromatograph, gas chromatograph, ion chromatograph, more low pressure liquid chromatograph, fast chromatograph, chemical sensing, thin layer chromatography, capillary electrophoresis and discontinuous flow or continuous flow yzer.Besides, there are some high-end detector, such as mass spectrometry or infrared can also combination and separation technology.But for the moment, and the key laboratory in colleges and universities has been applied more widely or gas phase and liquid phase separation technique.Using chromatography of college professional auxiliary research is becoming more and more popular.The chromatograph in recent years in the teaching plan of purchasing also share more highlights, according to incomplete statistics, liquid chromatography instrument sales alone ytical instruments of the world market for 20% of the total sales, world sales amounting to billions of dollars a year.Separation technology, China in 2013 sales of $1.552 billion, the separation of instruments in the world market share accounted for a large part, and from 2009 to 2014, erage growth rate is 14%.Chromatograph growing market demand, based on the use of the chromatograph in the constantly expanding, the college offers professional nearly dozens of professional research field with different professional chromatograph, food, medicine, biology, chemistry, and geology energy used chromatographic techniques to do scientific research and auxiliary equipment.Statistics show nearly 9% of the global separation technology requirements are from China.At present, the influence of liquid chromatograph and gas chromatograph in China, the largest of each technology are occupied by more than 10% global market share.And with the scientific research in colleges and universities gradually thorough, the demand for testing instrument is growing increasingly, and makes the chromatograph of procurement ranks as the leading role in university laboratory equipment.High performance liquid chromatograph as one of the most important separation technology, its application field test involving environmental, food and pharmaceuticals, and these three areas in China has maintained a rapid growth momentum, is expected to make the HPLC to maintain 13.6% annual growth rate over the next five years, in 2015, HPLC machine system is expected to be broken annual sales of $200 million.Mainly high-end for research of universal instrument and application of the conventional ysis of special high performance liquid chromatograph.儀器、儀表
