Resistivity Versus Conductivity
There are some situations where, instead of expressing results as conductivity, it may be easier to express as resistivity. One example is ultrapure water, where conductivity values can be extremely low, and it is better to use whole numbers (from resistivity) as opposed to fractions (if expressed as microSiemens). These two units are exactly the inverse of each other: the reciprocal of 0.10 µS/cm [or 1/(0.10 x 10-6 S/cm)] is 10 x 106 ohms-cm (10 MΩ-cm). This means both measurements can be used interchangeably and represent exactly the same result.
Why is it Important to Measure at a Specific Temperature?
Temperature plays a vital role when assessing samples for conductivity. As such, measurements are usually conducted at 25°C, which is a typical reference temperature. If measurements are done in a different temperature, it may affect results, as ionic activity increases with increasing temperature.
To avoid these errors, it is possible to correct values obtained at different temperatures by using a correction coefficient, expressed as a percentage per °C. If needed, this correction coefficient factor can be determined by measuring a sample at the reference temperature and again at a higher temperature. From these results, it’s possible to calculate the correction value.
