What is the required quality of water used in Accuracy of drying test mentioned in this SOP for calibration of Halogen Moisture Analyzer ?
Is Purified water sufficient or must be Distilled water ?

Also ,
2- What is the drying temperature for this Accuracy of drying test?
3- What is the drying time ?
4- Isn’t 0.2 g of water too small for the test, my information is that many moisture analyzers have minimum sample weight of 0.5 g , also my information that using such small sample weights reduces repeatability of moisture content test results (increases random error) ?
2- Accuracy of drying test in the SOP does not specify drying temperature.
3- Accuracy of drying test in the SOP does not specify drying time.
4- My little experience with moisture balances which have 1 mg least count that they show error message after pushing the start button if original sample weight is less than 0.5 g
