Process for determining the degree of hardness of water used as solvent involves measuring the conductivity of the water by means of a conductivity sensor and determining the overall hardness from the results by means of a characteristic calibration line. The conductivity sensor (1a, 1b) of the ...
By using in particular an aqueous ethanolic imidazole buffer with a pH value of 6.75, conditions can be set up in such a way that the o-CPC has an identical molar sensitivity with respect to Ca and Mg. The total water hardness of aqueous samples can thus be easily determined. ...

Can be seen from the curve of the relationship with the hardness increases, the plane strain fracture toughness (kic) values decreased significantly. This means that to determine the hardness of the spring hardness value should be based on the premise that meet the requirements of spring ...
