There are several general categories of salinity ranges to select in the Pyro Workbench

software:

Category

[mM]

Wastewater

0.5 - 1.5

1 - 3

10 - 30

Intermediate

1.5 - 5

3 - 10

30 - 100

Physiological

10 - 30

100 - 300

Seawater

15 - 40

30 - 80

300 - 800

For more accurate measurements it is possible to enter a known salinity [g/l] of the

sample in the software. This salinity value can be calculated by a simplified approach:

Salinity [g/l] = Conductivity [mS/cm] /2

Salinity [g/l] = Ionic Strength [mM] / 20

For experiments with strongly changing ionic strength, it is recommended to update the

settings and perform a new calibration in order to acquire accurate results.
