Ion size and conductivity
WebMost conductivity meters and other measurement options will use a common, approximated constant around 0.65 32. However, when measuring mixed water or saline water (with a conductivity value greater than 5000 uS/cm), the TDS constant should be higher: around 0.735 and 0.8 respectively 20. WebConductivity is the primary input control parameter used in automated chromatography systems to enable the generation of salt gradients or to control buffer dilution or in-line …
