海洋沉積物GBW07333/GBW07333黃海海洋沉積物標(biāo)準(zhǔn)物質(zhì)/GBW07333黃海海洋沉積物標(biāo)準(zhǔn)物質(zhì)/GBW07333黃海海洋沉積物/GBW07333黃海海洋沉積物標(biāo)土/GBW07333黃海海洋沉積物質(zhì)控樣/GBW07333黃海海洋沉積物主要成分/GBW07333黃海海洋沉積物標(biāo)準(zhǔn)值/GBW07333黃海海洋沉積物價(jià)格
本標(biāo)準(zhǔn)物質(zhì)用于海洋調(diào)合及檢測分析質(zhì)量控制,評價(jià)和驗(yàn)證分析方法的準(zhǔn)確度,校準(zhǔn)儀器,可作量值傳遞。
一、樣品制備
大桶中的黃海沉積物樣品放置若干天后,用虹吸法清除海水。將原樣于清潔通風(fēng)處晾干。將已風(fēng)干的沉積物樣放入烘箱中在120°C 下烘24h。冷卻后樣品采用高鋁瓷球磨機(jī)加工。交叉混磨后99.7%過200目篩,混勻分裝成70g/瓶。
