| titleOfInvention | A kind of measuring method and device of cigarette smoke Lead speciation |
| abstract | The invention discloses the measuring method and device of a kind of cigarette smoke Lead speciation, the measuring method includes trapping sample to be tested with filter disc, and extractant is added, and sample extracting solution is obtained by filtration in 30 ~ 50 min of ultrasonic extraction；Sample extracting solution is entered into reversed-phase liquid chromatography system, is separated by pumping the mutually inverted liquid chromatogram of A transport flow, the inorganic lead (Pb of efflux 2+ ) part, chlorination trimethyl lead (TML) part, chlorination triethyl group lead (TEL) part, chlorinated triphenyl base lead (TPhL) part be transferred to different solid-phase extraction column enrichments respectively, starting pump B transport flow mutually successively elutes the different shape lead of different solid-phase extraction columns enrichment and enters atomic fluorescence analysis after be enriched with.The device includes reverse-phase chromatography instrument and atomic spectrograph, and reverse-phase chromatography instrument and atomic spectrograph are linked in sequence, and is connected with solid-phase extraction device between the reverse-phase chromatography instrument and atomic spectrograph.The present invention can measure the sample of low concentration, and lead different shape is enriched on different solid-phase extraction columns, can avoid the variation of each form in enrichment and elution process to the greatest extent. |
