Improving Turbidity Measurement Reorts A Round Robin Study

摘要

ASTM International Committee D19 on Water has several active subcommittees that focus on turbidity. Recently, two new low-level turbidity methods have been completed that focus on unique measurement practices for the optimized measurement of up to five turbidity units. For high-level turbidity, three other task groups are currently developing new methods. The new and developing methods focus on the turbidimetric application, which include static (measurement of a captured sample), dynamic (sample delivered to an instrument for measurement) and in-situ (measurement in the process itself).
