Abstract

The invention discloses an automatic hydride generating system used for organotin headspace solid-phase microextraction. The system comprises a control unit, a hydride generating bottle, a first micro-scale metering pump, a second micro-scale metering pump, a first peristaltic pump, a second peristaltic pump and a third peristaltic pump; corresponding output ends of the control unit are respectively connected with the control ends of the first micro-scale metering pump, the second micro-scale metering pump, the first peristaltic pump, the second peristaltic pump and the third peristaltic pump; and the hydride generating bottle is respectively communicated with a buffer solution bottle, a hydride reagent bottle, a to-be-tested sample bottle, a pure water bottle and a drain bottle through pipes which are provided with the first micro-scale metering pump, the second micro-scale metering pump, the first peristaltic pump, the second peristaltic pump and the third peristaltic pump. By adopting the system, the functions of adding liquid, reacting, cleaning, draining and the like are finished automatically without manual intervention, so that the automation of hydrogen treatment is realized.

Description

technical field

[0001] The invention relates to a hydride generating system, in particular to an automatic hydride generating system for organotin headspace solid-phase microextraction. Background technique

[0002] Organotin compounds are metal organic compounds formed by the direct combination of tin and carbon elements, including 4 types: tetrahydrocarbyl tin compounds (R 4 Sn), trihydrocarbyl tin compounds (R 3 SnX), dihydrocarbyl tin compounds (R 2 wxya 2 ) and a hydrocarbon tin compound (RSnX 3 ), in the above general formula, R is an alkyl group or an aryl group, etc., and X is an inorganic or organic acid radical, oxygen or a halogen element, etc. Organotin is a substance that is extremely toxic to humans and organisms. In the marine field, organotin is mainly used in antifouling coatings for marine hulls. It is one of the most toxic chemicals introduced into the marine environment by human factors. The main ones are It is tributyltin chloride (TBT) and tripheny...
