Calibration

The Sonic Concentration Analyzer  uses an empirical technique for developing the calibration relationship between TOF and concentration.  The relationship is found by measuring the TOF for samples of known concentration and doing a curve fit to these measured values. The SCA software performs the curve fit and displays a plot of the curve and sample points (minimum three points, maximum thirteen).  An example calibration plot for a polymer emulsion is shown below. Once calibrated, the program will automatically converts TOF to concentration and will displays the results graphically.
