seracare試劑在應(yīng)用中具有四種常用規(guī)格
發(fā)布時(shí)間： 2021-05-25 點(diǎn)擊次數(shù)： 920次seracare試劑又稱(chēng)生物化學(xué)試劑或試藥。主要是實(shí)現(xiàn)化學(xué)反應(yīng)、分析化驗(yàn)、研究試驗(yàn)、教學(xué)實(shí)驗(yàn)、化學(xué)配方使用的純凈化學(xué)品。一般按用途分為通用試劑、高純?cè)噭⒎治鲈噭x器分析試劑、臨床診斷試劑、生化試劑、無(wú)機(jī)離子顯色劑試劑等。四種常用規(guī)格：有四種常用規(guī)格：優(yōu)級(jí)純或一級(jí)品（GR，精密分析和科學(xué)研究工作）；分析純或二級(jí)品（AR，重要分析和一般研究工作）；化學(xué)純或三級(jí)品（CP，工礦及學(xué)校一般化學(xué)實(shí)驗(yàn)）；實(shí)驗(yàn)試劑(L.P.)。優(yōu)級(jí)純（GR，綠標(biāo)簽）：主成分含量很高、純度很高，適用于精確分析和研究工作，有的可作為基準(zhǔn)物質(zhì)。分析純（AR，紅標(biāo)簽）：主成分含量很高、純度較高，干擾雜質(zhì)很低，適用于工業(yè)分析及化學(xué)實(shí)驗(yàn)。化學(xué)純（CP，藍(lán)標(biāo)簽）：主成分含量高、純度較高，存在干擾雜質(zhì)，適用于化學(xué)實(shí)驗(yàn)和合成制備。實(shí)驗(yàn)純（LR，黃標(biāo)簽）：主成分含量高，純度較差，雜質(zhì)含量不做選擇，只適用于一般化學(xué)實(shí)驗(yàn)和合成制備。基準(zhǔn)試劑含量應(yīng)該是99.9%～100%。隨著科學(xué)技術(shù)和新興工業(yè)的發(fā)展，對(duì)化學(xué)試劑的純度、凈度以及精密度要求愈加嚴(yán)格和專(zhuān)門(mén)化。在分析化學(xué)中應(yīng)用極為廣泛。試劑的品級(jí)與規(guī)格應(yīng)根據(jù)具體要求和使用情況加以選擇 。定級(jí)的根據(jù)是試劑的純度（即含量）、雜質(zhì)含量 、提純的難易，以及各項(xiàng)物理性質(zhì)。有時(shí)也根據(jù)用途來(lái)定級(jí) ，例如光譜純?cè)噭⑸V純?cè)噭约皃H標(biāo)準(zhǔn)試劑等等。
