庫倫法滴定試劑
庫存法主要用于測(cè)定含水量較低的樣品(10ug-10mg含水量),所以在樣品含水量比較低時(shí),庫倫法較容量法的優(yōu)勢(shì)較為明顯。
庫存法滴定儀器由陽極池和陰極池組成, 若兩池由隔膜分開即為有隔膜庫倫滴定法,實(shí)驗(yàn)選用有隔膜庫侖試劑,反之則選擇無隔膜庫侖試劑。經(jīng)驗(yàn)地, 無隔膜庫侖溶劑用于有隔膜儀器時(shí)表現(xiàn)出更高的滴定效率和精度。
Hydranal®庫倫法試劑
包含陰極液和陽極液
優(yōu)點(diǎn):
有隔膜試劑
有隔膜的庫存水分儀在測(cè)定中需要兩種試劑,一種是庫倫法陽極液,另一種為庫倫法陰極液,兩種試劑被隔膜分開,以防止兩種試劑互相干擾

水標(biāo)準(zhǔn)品
當(dāng)您的儀器長(zhǎng)時(shí)間使用后,您對(duì)儀器的精確性有點(diǎn)懷疑的時(shí)候,您就需要對(duì)儀器進(jìn)行校準(zhǔn)。或者當(dāng)您的試劑儲(chǔ)存的時(shí)間太長(zhǎng)后,您認(rèn)為試劑的滴定度開始發(fā)生了變化,您也要對(duì)試劑進(jìn)行一次重新標(biāo)定,以保證您的滴定能得到正確的結(jié)果。
Fluka 還為您提供用于校準(zhǔn)卡氏爐的固體KF標(biāo)準(zhǔn)品。由于卡氏爐的這種特殊性,因此校準(zhǔn)儀器和重新標(biāo)定試劑的水分標(biāo)準(zhǔn)品也是的。這里使用的水分標(biāo)準(zhǔn)品是固體的。通過與樣品同樣方式,將水分標(biāo)準(zhǔn)品中的水導(dǎo)入滴定池中,這一過程與測(cè)定樣品中含水量的方式是一樣的,因此其結(jié)果也是可信的。
