As one of the most commonly used analytical laboratory sample pretreatment instruments, solid phase extraction has been more and more widely used. Solid phase extraction technology is to use solid adsorbent to adsorb the target compounds in liquid samples, separate the sample matrix and interfering compounds, and then use eluent to elute or heat desorption to realize the separation and enrichment of the target compounds.
On July 27, in order to help 3million + users solve the pain and confusion of model selection, the instrument information network held“Easy model selection”In the fourth episode of the live broadcast program, this episode focuses on the category of”solid phase extraction instrument”, and brings some practical experience for users to understand the technology procurement of solid phase extraction instrument from multiple dimensions, such as selection principles, technical progress, industry standards, market performance, user reputation, use feedback, application support, after-sales service, case sharing, real machine evaluation, etc.
本期”Easy model selection”栏目，中国医学科学院药物研究所研究员张金兰和睿科集团技术研究院院长陈小华做客直播间，两位专家回顾了与固相萃取仪的“不解之缘”，畅谈了近年来固相萃取仪国内外技术进展，并进行了固相萃取仪选型经验分享，还对固相萃取仪未来的研发与应用趋势表达了自己的看法。

Mr. Zhang Jinlan recalled that he had been exposed to solid-phase extraction technology since 1992. At that time, he still used manual solid-phase extraction columns. He didn’t really touch solid-phase extraction instruments until 2006. Now, he has been using solid-phase extraction for 30 years. For the development of key technologies of solid-phase extraction, Mr. Zhang Jinlan believes that automatic sampling technology, high-throughput processing of samples, high-throughput analysis of samples, and the development of stationary phases are all very important. At present, China pays great attention to the domestic substitution of solid-phase extractors and encourages the development of domestic solid-phase extractors. Mr. Zhang is very looking forward to domestic solid-phase extractors. For the selection of solid-phase extraction instrument, Mr. Zhang believes that factors such as the sample detection volume in this field, whether the forward and reverse directions are compatible, and the repeatability and precision of the instrument should be fully considered.
Chenxiaohua, President of Ruike Group Technology Research Institute
President Chen Xiaohua came into contact with solid phase extraction technology during his doctoral study in the Netherlands in 1989, and came into contact with foreign solid phase extraction instruments in 1992. As a representative of domestic solid-phase extraction instrument manufacturers, President Chen Xiaohua believes that manufacturers have more considerations for solid-phase extraction instruments, such as flow rate control, software, scalability and so on, which are the key technologies of solid-phase extraction instruments. Solid phase extraction (SPE) has experienced a process from recognition to acceptance in China, which solves the problem that the traditional pretreatment process is particularly long. The upgrading of materials has promoted the development of SPE technology. Nowadays, automated SPE has solved many problems of users. For instrument manufacturers, the development trend of solid phase extraction instrument in the future is miniaturization, integration, intelligence and informatization. The domestic solid-phase extraction instrument was first started by imitating imported products. After years of honing and fully combining with the needs of users, it has sufficient confidence in serving domestic users. The domestic solid-phase extraction instrument represented by Ruike can almost achieve 100%replacement in the fields of environment and food. At present, Ruike has put more than 2000 instruments in China. In terms of instrument selection, President Chen Xiaohua believes that the practicality and intelligence of the instrument should be considered. The two teachers also reached an agreement on the selection of solid-phase extraction instrument:the appropriate solid-phase extraction instrument should be selected according to the real needs and testing tasks.
Big data helps the selection of solid phase extraction instrument (reporter:Zeng Mingquan (right), head of instrument information network shopping guide platform)
Zeng Mingquan, the person in charge of the shopping guide platform of the instrument information network, mainly introduced the selection of solid phase extraction instrument using the big data of the instrument information network. Users will pay attention to the automation degree (manual, full-automatic, semi-automatic), extraction channel (such as single channel, four channel, eight channel or more), price (range span is very large), etc. when purchasing solid-phase extraction instrument. The traditional means of simply searching solid phase extraction instrument can no longer meet the needs of users. Now users need a professional shopping guide platform to help users identify and judge.
