標(biāo)準(zhǔn)品和對(duì)照品的區(qū)別:
☆對(duì)照品:用于鑒別、檢查、含量測(cè)定和校正檢定儀器性能的標(biāo)準(zhǔn)物質(zhì)。對(duì)照品系指用于生物制品理化等方面測(cè)定的特定物質(zhì),由生產(chǎn)單位采用與制品生產(chǎn)工藝相同的方法制備。對(duì)照品應(yīng)盡可能與制品原液配方一致,穩(wěn)定性較差的,可加不含對(duì)測(cè)定有干擾物質(zhì)的適宜的穩(wěn)定劑。對(duì)照品由國(guó)家藥品檢定機(jī)構(gòu)審查認(rèn)可,其標(biāo)準(zhǔn)應(yīng)不低于制品的質(zhì)量標(biāo)準(zhǔn)。
☆標(biāo)準(zhǔn)品:用于生物檢定、抗生素或生物藥品中含量或效價(jià)測(cè)定的標(biāo)準(zhǔn)物質(zhì),以效價(jià)單位(U)表示。國(guó)家標(biāo)準(zhǔn)品及生物參考品系指用于鑒別、檢查含量或效價(jià)測(cè)定的標(biāo)準(zhǔn)物質(zhì),其制備與標(biāo)定應(yīng)符合“生物制品國(guó)家標(biāo)準(zhǔn)物質(zhì)制備和標(biāo)定規(guī)程”要求,并由藥品監(jiān)督管理部門指定的機(jī)構(gòu)分發(fā)。企業(yè)工作標(biāo)準(zhǔn)品或參考品必須經(jīng)國(guó)家標(biāo)準(zhǔn)品或參考品標(biāo)化后方能使用。

訂購(gòu)須知:
產(chǎn)品僅用于科研客戶訂購(gòu)時(shí)需留下詳細(xì)的寄送信息;收到貨以后,請(qǐng)先驗(yàn)貨,看包裝有無(wú)破損,如有破損請(qǐng)不要簽收,并及時(shí)反饋給我們,我們會(huì)重新發(fā)貨;實(shí)驗(yàn)的過(guò)程中,請(qǐng)嚴(yán)格按照說(shuō)明書進(jìn)行操作,如遇技術(shù)問(wèn)題可與我司技術(shù)部咨詢。
對(duì)照品實(shí)驗(yàn)方法與判定:
1.對(duì)照品溶液的穩(wěn)定性
2.對(duì)照品溶液的配制:精密量取腦對(duì)照品適量,加無(wú)水乙醇制成每1ml含腦1mg的溶液,作為對(duì)照品溶液。
3.色譜條件:以交聯(lián)鍵合聚乙二醇為固定相的毛細(xì)管柱;柱溫120℃;進(jìn)樣口溫度250℃;檢測(cè)器溫度250℃;分流進(jìn)樣,分流比10:1。理論塔板數(shù)按腦計(jì)算應(yīng)不低于10000。
4.實(shí)驗(yàn)方法:配制的對(duì)照品溶液,一份置冷處保存,一份置室溫中保存,在第1、3、7、10、15天重新配制一份對(duì)照品溶液,三種儲(chǔ)備液同時(shí)稀釋制成每1ml中約含50ug的溶液。照氣相色譜法,并依據(jù)新對(duì)照品的峰面積計(jì)算原對(duì)照品溶液的含量。記錄下來(lái),保證原對(duì)照品溶液含量在考察期相對(duì)平均偏差不超過(guò)2.0%,驗(yàn)證對(duì)照品溶液在使用期內(nèi)穩(wěn)定可靠。
標(biāo)準(zhǔn)品的管理:
(一)接收
