In recent years, China's testing standards in the fields of environment, food and pharmaceuticals have become stricter and stricter, and the content of test samples has become lower and lower, which poses more and more challenges to sample pretreatment technology.

The "Shandong Province Sample Pretreatment Technology Innovation Conference 2019" sponsored by Shandong Analytical Testing Association and EWG1990 Instrument Learning Network was held in Jinan, Shandong Province, on June 28, 2019. With the theme of "Innovative Idea of Sample Pretreatment", the conference invited research experts, analysts and testers and relevant personnel in the field of pretreatment all over the country to share the related problems encountered in the pretreatment process of laboratories and the cutting-edge innovative means of pretreatment, so as to improve the overall efficiency of laboratories and control the cost of human resources. Qingdao Shenghan Chromatograph Technology Co., Ltd. was invited to attend the event.

During the conference, Shenghan of Qingdao, who insisted on independent innovation, received a lot of attention, and showed the participants the ion chromatograph developed and manufactured by himself and the whole series of consumables. As soon as Shenghan consumables supermarket appeared, it attracted a large number of new and old customers with a variety of chromatographic columns, suppressors, pretreatment columns, degassers and other products.

"Why should samples be pretreated?"

In the process of analysis, the impurity interference, organic matter or metal ions in the sample will pollute the packings of column, reduce the separation ability and service life of the column, and the impurity ions will interfere with the separation of ions. So the sample pretreatment column should be used. It can effectively remove the organic matter and impurity ions in the sample, avoid the contamination of impurities on the column and the influence on the separation effect, effectively prolong the service life of the column and improve the separation effect of the sample.
