Description
Technical field
The present invention relates to metrology and measurement standard transmission of quantity value technical field, especially relate to a kind of plasmatron spectrographic analysis hybrid ionic standard substance (standard model) that is widely used in the research and the monitoring of departments such as metallurgy, geology, environmental protection, medical and health, agricultural, chemical industry, food.
Background technology
In industries such as metallurgy, geology, environmental protection, medical and health, with emission spectrographic analysis as conventional method of analysis.Emission spectrographic analysis is a kind of relative measurement method, must trace to the source by the standard substance of respective element in the middle of The whole analytical process.At present, China is used for national calibration hybrid metal and semimetal ion standard substance quite lacks, and this is embodied in two aspects: (1) hybrid metal and semimetallic elements kind are few; (2) concentration series is incomplete, so that many laboratories can only be uneven according to the interim preparation of standard substance and the kind of analyzed object purchase one matter.For example, environmental monitoring department will carry out water analysis, and adopting plasma emission spectrometer is a kind of desirable method.Yet, in order to finish this analysis must move liquid, dilution, constant volume preparation hybrid ionic respectively from the standard substance of a plurality of one matters standard substance.This be one not only loaded down with trivial details but also bring the course of work of hidden danger can for the inaccuracy of data.Careless slightly, just can not make science, comprehensive, the accurate analysis to the analysis transmission of standard value.Above-mentioned state can't adapt to the needs of the numerous technical field analytical tests of China.Present domestic such standard substance that still do not have, the external report that such standard substance is not arranged yet.So the national standard substance of development hybrid metal and semimetal ion is that various circles of society are engaged in the needs of carrying out the work in the laboratory of emission spectrographic analysis, plasma emission spectrometer metering needs of tracing to the source especially.
Summary of the invention
Technical matters to be solved by this invention provides a kind of highly sensitive, accuracy good, analysis speed is fast plasmatron spectrographic analysis hybrid ionic standard substance.The technical scheme that the present invention solves its technical matters employing is: a kind of plasmatron spectrographic analysis hybrid ionic standard substance, contain boron (B) 1.00～10.00mg in its 1L capacity, germanium (Ge) 1.00～10.00mg, molybdenum (Mo) 1.00～10.00mg, niobium (Nb) 1.00～10.00mg, silicon (Si) 1.00～10.00mg, tantalum (Ta) 1.00～10.00mg, titanium (Ti) 1.00～10.00mg, tungsten (W) 1.00～10.00mg and zirconium (Zr) 1.00～10.00mg and lytic agent 100mL, all the other are element body, the unit of element body is mL, lytic agent is the ultrapure rank hydrofluorite of technology, and element body is that titanium steams water.The present invention is owing to adopt technique scheme, not only can provide the material of tracing to the source for daily emission spectrographic analysis test, and be that technical foundation has been widened in national measurement verification work, also remedied the blank spot of national standard substance simultaneously in hybrid metal and semimetal ion standard substance field.
Boron among the present invention (B), germanium (Ge), molybdenum (Mo), niobium (Nb), silicon (Si), tantalum (Ta), titanium (Ti), tungsten (W), zirconium (Zr) are for providing the material of tracing to the source of emission spectrographic analysis test, and it is that the ultrapure rank hydrofluorite of element body, technology can dissolve above-mentioned metal and semimetal one matter as lytic agent that titanium steams water.Above-mentioned metal and semimetal one matter (standard substance) should meet the regulation of " country of JJG1006-94 People's Republic of China (PRC) metering technology normalized ".All components among the present invention all at home market buy.
Compound method of the present invention is as follows: adopt the electronic balance of 100,000/precision to take by weighing a certain amount of metal or semimetal one matter respectively, dissolve by microwave heating with technology ultra-pure hydrogen fluoric acid, after dissolving finishes, be transferred in the recorder jar of 1L capacity, blend titanium steaming water and evenly allocate and be diluted to 1L.The ultrapure rank hydrofluorite of technology among the present invention is 100mL (account for 10% of 1L, promptly concentration is 10%).
