How does OLI rigorously calculated TDS?
OLI originally developed the TDS calculation according to parameters set forth in ASTM D5907-03 (American Society of Testing Methods, West Conshocken, PA, United States). Recently this technique was modified to follow the parameters in ASTM D5907-18.
Both techniques heat a 1.0 L of solution of liquid to 180 oC which should remove all the volatile components. The mass remaining is the TDS in mg/L
