20120138813 | EVALUATING A CLEANING SOLUTION USING UV ABSORBANCE - A process for evaluating a cleaning solution is described, The process includes: (a) subjecting a solution, including a solute and a solvent, to sonic energy to create a sonicated solution; (b) measuring UV absorption of said sonicated solution to produce a sample UV absorbance spectra; (c) obtaining a reference UV absorbance spectra; (d) scaling said reference UV absorbance spectra to said sample UV absorbance spectra at a lower range of said UV spectrum;(e) subtracting from said reference UV absorbance spectra said sample UV absorbance spectra to produce a differential UV spectra; and (f) evaluating at or near a peak of said sample UV absorbance spectra said differential UV absorbance spectra to determine whether said sonicated solution is activated. | 06-07-2012 |
20090290143 | Evaluating a Cleaning Solution Using UV Absorbance - A process for evaluating a cleaning solution is described. The process includes: (i) subjecting a solution, including a solute and a solvent, to sonic energy to create a sonicated solution; (ii) measuring UV absorption of the sonicated solution to produce a sample UV absorbance spectra; (iii) obtaining a reference solution, which includes a solute concentration that is similar to that of solute concentration in the sonicated solution; (iv) measuring UV absorption of the reference solution to produce a reference UV absorbance spectra; (v) scaling the reference UV absorbance spectra to the sample UV absorbance spectra at a lower range of the UV spectrum; (vi) subtracting from the reference UV absorbance spectra the sample UV absorbance spectra to produce a differential UV spectra; and (vii) evaluating at or near a peak of the sample UV absorbance spectra the differential UV absorbance spectra to determine whether the sonicated solution is activated. | 11-26-2009 |
