Abstract

The invention discloses a vehicle-mounted portable liquid chromatographic instrument. The liquid chromatographic instrument comprises a double-motor straight-belt infusion pump, a sample feeding valve, a fluorescence and ultraviolet-visible absorption integral circulation tank, an optical fiber, an optical fiber spectrograph, a light source and a built-in wireless router, wherein the double-motor straight-belt infusion pump is connected with an inlet of the sample feeding valve; an outlet of the feed sampling valve is connected with a high-performance chromatograph column; an outlet of the high-performance chromatograph column is connected with the circulation tank; the light source is guided into the circulation tank through the optical fiber; transmission light or fluorescence of the circulation tank is guided into the optical fiber spectrograph through the optical fiber, is converted to an absorbance or fluorescence signal to be output; a control module is used for controlling and carrying out data collecting and processing on the infusion pump, the sample feeding valve and the optical fiber spectrograph through a wireless network. The vehicle-mounted portable liquid chromatographic instrument is complete in function, high in precision, small in size, good in anti-seismic property and applicable to field fast check of food safety and environmental protection.

Description

technical field [0001] The invention relates to the technical field of chromatography, in particular, the invention relates to a vehicle-mounted portable liquid chromatograph. Background technique [0002] High performance liquid chromatography (HPLC), as a routine laboratory equipment, has a wide range of uses. HPLC can separate thermally labile and nonvolatile, dissociated and nondissociated species, and a wide range of molecular weights. Cooperating with the sample pretreatment technology, its high resolution and high sensitivity make it possible to separate and simultaneously measure substances with very similar properties, and can separate trace components in complex phases. With the development of stationary phase, it is possible to complete the separation of biochemical substances under the condition of fully maintaining their activity. HPLC has become the most promising method to solve biochemical analysis problems. Due to the advantages of high resolution, high se...
