CT - 1 Cloride Analyzer
|
Coulometric titrator for laboratory determination of chloride contents in liquid samples
|
|
CT-1 is a prompt laboratory instrument for hydrogeological, chemical and biochemical analyses where its accuracy, high measuring speed and low operation costs can be appreciated .
Typical
applications
Chloride analyzer CT-1 (coulometric titrator) is a desk laboratory instrument for determination of chloride contents in liquid samples by coulometric titration analysis. The titration reagent - silver ions - is generated electronically from the silver electrodes.
After sample dosing into the measuring cup (e.g. using a
capillary micropipette) the instrument starts to titrate
automatically and the measured chloride concentration is
displayed. The most important parameters of titration can be set by an operator in order to optimize measuring conditions for various chloride concentrations. The calibration mode allows result matching in accordance with standard samples. Optional PC interface available. |
