Turbidity Definition - What is it?Turbidity Definition - What is it?Turbidity is the “optical property that causes light to be scattered and absorbed rather than transmitted in straight lines through the sample.”Ref: Standard Methods for Examination of Water and Wastewater
Turbidity is the clarity of the water sample.

Scattered Light at 90°
Light Scattered by Particles
Turbidity is the measure of the amount of light scattered by particles in a sample. A beam of light passes through a sample containing suspended particles. The particles interact with the
light and scatter the light. A detector at 90° measures the intensity of the scattered light.

ISE (Sodium) AnalyzerISE (Sodium) Analyzer
mV is proportional to -log ([H+] + a[Na+])
mV is proportional to -log ([Na+] + b[H+])
pH glass electrode
Typically, a is small, so unless [Na+] is very large, there is no error.
Na glass electrode
For the electrode to respond properly to sodium, the H+ concentration must be low
enough, i.e. pH high enough, for the second term to be negligible.

Analyzer response is directly proportional to log Na.
Standardization is a two point calibration using 10 ppb and 100 ppb standards.
