Total Chromium Pack Test
Cautions:
1. The chromium (total ) pack test allows to measure both dissolved trivalent and hexavalent chromium.If the sample contains precipitate or particulates,use acid or other reagent to dissolve chromium before the measurement.
2. The normal pH range is less than 10.If necessary,adjust the pH with diluted sulfuric acid.
3.Ensure that pack test tube is filled up to the half.
4.Keep sample temperature in the range 20-40℃.Lower temperature necessitates longer reaction time.
5.Compare the color with the color chart just after 30 seconds.After 1 minute,the color fades away or can change to other color.
