Kapsap is an extension of 'known addition potentiometry, a procedure commonly used to potentiometrically determine a range of analytes using the technique of standard addition
Kapsap however, employs unique manipulations of standard solutions, samples and base solutions containing potentiometric sensors that can allow the fully automated analysis of up to 400 samples.
Easy-to-automate analytical procedures - sensor not transported to the samples.
Analysis of previously troublesome sample types is now possible.
Kapsap requires only a small volume of sample, which is then added to a relatively large volume of base solution.
This eliminates the problems associated with difficult samples, which previously could not be analysed by the standard procedures due to the presence of interfering ions or excess acidity / alkalinity.
Kapsap's procedures automatically correct for any potential carry-over from one analysis to the next, eliminating the need to 'washout' between samples.
During the analysis sequence, Kapsap determines the concentration of analyte in the base solution, which is adjusted to ensure that he sensing electrode operates in its linear range an d the results are acceptable, and that the overall analysis time (speed of response) is acceptable.
Since the sensor is maintained in a constant ionic strength environment, and is not transported around the samples, its performance is greatly improved and its life extended.
Where the accuracy of a titration is not required, or the end-point is difficult to detect, Kapsap can replace the potentiometric titration usually required for the determination of acidity/alkalinity.
Advantages: Fully automates the analysis of up to 400 samples.
Analyte analysis is by standard addition and Ion selective electrode.
Small sample size: 1 to 2ml.
Small foot print.
The system automatically and accurately pipettes the sample - therefore no need for manual time-consuming decanting of the sample.
Full PC control with bi-directional Lims communication.
Kapsap can be configured to analyse a wide range of determinands: acidity, alkalinity, ammonia, bromide, chloride, cyanate, cyanide, fluoride, iodide, nitrate, potassium, sodium, sulphide, and more.
