Computer-controlled automatic liquid micro-extraction device

TL;DR: In this article, a hollow fibrous membrane micro-extractor was proposed to solve the defects of multiple hand-operated processes, hardiness in controlling the operation, poor repeatability and the like existing in the liquid-liquid-liquid microextraction.

TL;DR: In this paper, an extraction/back extraction kinetic studying device based on a rising single droplet method is used for the field of extraction kinetic analyzing, which mainly includes a support, an extraction device and a feeding device.

TL;DR: In this paper, an anionic surfactant automatic analysis device is presented, which consists of an extraction assembly, a back extraction assembly and an electromagnetic multiported valve, an automatic injector and a detection device.

TL;DR: In this article, a soil extraction method consisting of multiple clean and dry empty reagent bottles are prepared and placed in the reagent bottle disposing area; S2, the to-be tested soil is added to a material feeding device, and S3, the robot device is controlled by the control device for moving the reagents to an oscillation device for oscillation for a certain time.

TL;DR: In this paper, the extractant and eluent are the same and only one pump is used for pumping the elusent and extractant, which is the first step towards the separation of the two components.

TL;DR: In this article, a sample containing a component to be analyzed is injected into a flowing stream of carrier liquid and flowed past one side of a two-sided membrane, while a receiving liquid is flowed past the other side of the membrane.

TL;DR: In this article, an all-in-one heavy metal online analyzer is presented, which comprises a multi-ported valve, at least one reagent bottle, a pure water cylinder, a plunger pump, a mixing cylinder, and a waste liquid cylinder.

TL;DR: In this article, a film abstractor combined with the ion chromatography, comprising three pumps, two six-way valve, a pre-column and a paper abstractor, was used to detect trace amounts of anion in non-water-solubility organic matter.
