No gels nor precipitates resulted in the course of the titrations and the accuracy of the method was comparable to that obtained using benzoic acid as the primary standard. Conductometric titrations were also performed using sulfamic acid dissolved in two systems, dimethyl formamide and glacial ...
The molarity of the volumetricsolutions is determined by an appropriate number of titrations.The repeatability does not exceed 0.2 per cent (relative standarddeviation).Volumetric solutions are standardised by the methods describedbelow. When a volumetric solution is to be used in an assayin which ...
Resuspend the cells in primary antibody, diluted in medium without addedazide, as determined by priortitration(100ml per 107cells). Theprimary and secondary antibodiesshould be sterilized using a 0.2 microncellulose acetatefilter. 3. Incubate the cells, with occasional shaking, at 4°C for ...

Primary standards are typically used in titration to determine an unknown concentration and in other analytical chemistry techniques.Titrationis a process in which small amounts of a reagent are added to a solution until a chemical reaction occurs. The reaction confirms that the solution is at a s...
