詳細(xì)介紹

產(chǎn)品名稱:BOD接種液-環(huán)境分析

分析方法:滴定(容量)分析法 - 氧化還原滴定法

研制依據(jù):HJ 505-2009 水質(zhì) 五日生化需氧量(BOD5)的測定 稀釋與接種法

制備方法:本標(biāo)準(zhǔn)物質(zhì)采用純度經(jīng)準(zhǔn)確定值的工業(yè)廢水為溶質(zhì),以超純水為溶劑,在室溫(20±3)℃潔凈實驗室中采用重量-容量法配制而成。


溫馨提示:

經(jīng)營范圍:

計量儀器、國家標(biāo)準(zhǔn)物質(zhì)、進(jìn)口標(biāo)準(zhǔn)品、冶金標(biāo)樣、標(biāo)準(zhǔn)氣體、藥典對照品、標(biāo)準(zhǔn)菌種細(xì)胞


產(chǎn)品名稱:BOD接種液-環(huán)境分析

標(biāo)準(zhǔn)物質(zhì)用途:本標(biāo)準(zhǔn)物質(zhì)可作為BOD接種液。

保存條件:陰涼密閉及避光條件下保存。使用前應(yīng)恒溫至(20±3)℃,并充分搖動以保證均勻。本標(biāo)準(zhǔn)物質(zhì)打開后應(yīng)一次性使用,使用中嚴(yán)格防止沾污。最小取樣量100mL,加稀釋水定容到1L即為接種稀釋水。

溯源性:本標(biāo)準(zhǔn)物質(zhì)采用滴定法進(jìn)行量值核驗。通過使用滿足計量學(xué)特性要求的制備、測量方法和計量器具,保證標(biāo)準(zhǔn)物質(zhì)量值的溯源性。

不確定度來源:主要由定值以及均勻性、穩(wěn)定性等不確定度合成。
