The Effect of Temperature on Conductivity Measurement (TDS) Technical

The conductivity of all solutions changes as the solutions’ temperature changes. It is a fundamental, practical requirement in the field of conductivity measurement that test measurements taken at different temperatures can be compared. This comparison can be facilitated by the use of Temperature Compensation, which provides an estimate of the samples’ conductivity at a common…

ANALYSIS OF SURFACTANTS 2nd Edition – Technical

Anionic surfactants account for about 50% of surfactant use in Europe and about 60% in the United States. Most are high-foaming but sensitive to hard water and therefore require the addition of substances to complex calcium and magnesium ions (i.e., detergent builders). They are more effective than other surfactants in particulate soil removal.
