The Full Automatic Liquid liquid abstraction instrument that oils is analyzed in water.
Background technology
It flourishes with China's offshore oil exploration and exploitation is movable, all kinds of row seas pollution that normal development activities generate
Object (main includes production water, sanitary sewage, drilling cuttings, mud, all kinds of rubbish) and oil spill accident lead to the wind that marine environment faces
Danger increasingly increases, and to ensure the marine eco-environment, the oils analysis in seawater has become marine environmental monitoring and appraisal
In essential analysis project.There is difference in the oils analysis method in seawater, but sample pretreatment process is consistent, that is, uses
Different extractants carries out liquid-liquid extraction to seawater sample.Extraction process usually requires in sampling location and by being accomplished manually.With
For ultraviolet spectrophotometry, sampling bottle acquisition seawater sample it is acidified after be fully transferred to separatory funnel, be manually added one
Quantitative n-hexane, then shakes, and concussion mode is generally by the way of hand or oscillator, stratification after concussion 2 minutes.
After the completion of extraction, water sample is collected first and measures volume for result calculating, it is to be measured then to collect extract liquor.From seawater sample
To the collection of extract liquor, entire sample pretreatment process is both needed to manually participate in sample introduction, and labor intensity is big, and sample analysis timeliness
Difference.After the completion of extraction, separatory funnel also needs manually to clean, and further increases the labor intensity of experimenter.
Existing Full Automatic Liquid liquid abstraction instrument is shaken using rotation, overturns the modes such as concussion, air-flow concussion on the market at present,
Although realize the automation of extraction process itself, at the same equipment component solve toxic gas volatilization and separatory funnel cleaning
Problem, but seawater sample introduction, extractant sample introduction and seawater-extract liquor separation process still need to be accomplished manually, the degree of automation is not high,
The requirement that timeliness height, high degree of automation are analyzed under large sample amount still be cannot be satisfied for example, in Publication No.
In the patent of CN201399261Y, vegetable and animals oils and mineral oil separation are mainly solved, and are largely that principle is analyzed, extraction
It is all mechanical agitation to take mode not, and Liquid liquid Separation mode is not all Absorption quantity pipe.
