Du søgte efter: Vandbestemmelse (ved Karl Fischer-metoden) Standarder
Disse vandstandarder er det foretrukne valg til overvågning af Karl Fischer-instrumenters ydeevne, bestemmelse af titrering af volumetriske Karl Fischer-reagenser og verifikation af endelige vandindholdresultater. De ampullerede væskestandarder er direkte sporbare til NIST og produceres under streng kontrol ved hjælp af validerede procedurer. Vandstandarder på 1 % og 0,1 % anbefales til volumetriske anvendelser, mens 0,1 % og 0,01 % anbefales til coulometriske anvendelser.
