實(shí)驗(yàn)背景
測(cè)定樣品中的重金屬含量,首要條件就是保證樣品實(shí)驗(yàn)全程不接觸到任何金屬材質(zhì)的物品;若是處理少量樣品,使用陶瓷研缽即可很好處理樣品;但碰上高通量樣品處理時(shí),使用常規(guī)的研磨器械,總免不了讓樣品接觸到金屬材質(zhì)的器具;如果樣品還是較難研磨的韌性樣品,那實(shí)驗(yàn)操作起來(lái)就相當(dāng)棘手。
最近,上海凈信就接到了這樣的用戶(hù)挑戰(zhàn):測(cè)定一次性餐具中的重金屬含量。
這種新型一次性餐具有防水防油的特點(diǎn),且韌性也較好。這些特點(diǎn)使產(chǎn)品非常符合使用標(biāo)準(zhǔn),但正因此也增大了樣品研磨的難度。
實(shí)驗(yàn)步驟
需了解具體步驟,請(qǐng)致電廠(chǎng)家
實(shí)驗(yàn)結(jié)果
研磨后的樣品呈細(xì)膩粉末狀,利于成分含量的測(cè)定;且實(shí)驗(yàn)全程使用的器具均為塑料/陶瓷材質(zhì),避免了外界因素對(duì)于實(shí)驗(yàn)結(jié)果的干擾。
