The instrument developed by Dalian Zhuoer High-Tech Co., Ltd. which applies supercritical fluid technology to sample pre-processing for testing passed acceptance and delivery smoothly in April 2016 at a certain Institute of the State Oceanic Administration. So far, it has been running smoothly for more than half a year and has been in good condition all the time.

　　The instrument was launched in the second half of 2014, and the first prototype prototype was successfully developed and put into test in June 2015. After six months of improvement, adjustment and optimization, it was finalized at the end of 2015 and officially sold to the outside world since 2016. Previously, the market share of similar instruments sold in China was monopolized by imported brands. The appearance of Zhuoer's instrument filled the gap in China.

　　Compared with imported brands, the performance indicators of this pretreatment instrument are consistent with those of imported brands. The volume of this instrument is five times as large as that of imported brands, but the price is less than two-thirds of that of imported brands. It can also be tailored to meet customer requirements and provide customized services. Therefore, it is more suitable for the actual scientific research needs of Chinese users than the similar evaluation of imported brands.
