Procedure for Ba measurement

Run program 20 Barium to evaluate barium in the range from 2 to 100mg/L Ba. Swirl 10 mL of sample and BariVer 4 Barium Reagent Powder Pillow content in the cell to prepare the sample. Add 10 mL of sample in the another cell. After 5 minutes, clean the blank cell and insert in the instrument. Remove the blank, insert the pretreated sample cell and analyze testing results. The measurement wavelength for spectrophotometers is 450 nm. The required wavelength for colorimeters is 420 nm.
