Dilution Precision in Concentration Measurements
Q. Do I determine detergent dilution by weight or by volume or both?
A. In a laboratory setting, the most common method is to either make a weight/weight dilution (10-20 g Alconox detergent in 990 g of water), or a weight/volume dilution (10-20 g Alconox in 990 mL of water) for 1-2% solutions. In manufacturing situations, often directions are written volume/volume or volume/weight.
