庫倫(lun)法滴定試劑
庫存法主(zhu)要用于測定含(han)水(shui)量(liang)(liang)較(jiao)(jiao)低的樣(yang)品(pin)(10ug-10mg含(han)水(shui)量(liang)(liang)),所以在樣(yang)品(pin)含(han)水(shui)量(liang)(liang)比較(jiao)(jiao)低時,庫倫法較(jiao)(jiao)容量(liang)(liang)法的優(you)勢(shi)較(jiao)(jiao)為明顯。
庫存法滴定儀器由陽極池(chi)和(he)陰極池(chi)組成, 若兩池(chi)由隔(ge)膜(mo)分開即為有隔(ge)膜(mo)庫倫滴定法,實驗選用有隔(ge)膜(mo)庫侖(lun)試(shi)劑(ji),反之則選擇(ze)無隔(ge)膜(mo)庫侖(lun)試(shi)劑(ji)。經驗地, 無隔(ge)膜(mo)庫侖(lun)溶劑(ji)用于(yu)有隔(ge)膜(mo)儀器時表現出(chu)更高的滴定效(xiao)率(lv)和(he)精度(du)。

水標準品
當您的儀(yi)器長時間使用后,您對儀器的精確性有點懷疑的時候,您(nin)就(jiu)需(xu)要對儀器(qi)進行校準。或者(zhe)當您的試劑儲存的時間太長后(hou),您認為試劑的滴定度開(kai)始發生了變化,您也要對試劑(ji)進行一(yi)次重新標定,以保證您的滴定(ding)能得到正確的結(jie)果(guo)。
Fluka 還為(wei)您提(ti)供用(yong)于(yu)校準卡氏爐(lu)的固體KF標準(zhun)品(pin)。由于卡(ka)氏爐的這種特(te)殊性,因此(ci)校準(zhun)(zhun)儀(yi)器和重新標定試劑(ji)的水(shui)分標準(zhun)(zhun)品也是的。這里使用的水分標準品是(shi)固體(ti)的。通過與樣品同樣方式,將(jiang)水分標(biao)準品(pin)中的(de)水導(dao)入滴定池中,這一過程與(yu)測定樣品中含水量的方式是一樣的,因此其結果(guo)也是(shi)可信的。
