Karl Fischer titration is a technique used for measuring the water content of various substances, such as polymers, chemicals and oils. Karl Fischer titration measures water content with precision down to parts per million (ppm). The reagents generated during coulometric titration react selectively with any water present in the sample. This selectivity makes Karl-Fischer titration superior over weight-based techniques like TGA.

For measuring water content in any sample. Our 139 Metrohm 831 KF Coulometer in combination with a Thermoprep 832 oven can measure water content from ppb-level to 100% with ease.
