In addition, measured sample concentrations were higher and recovery was poor (elevated) after hyaluronidase treatment.
Specialized photography software applications and analysis of pixel intensity enables quantification of sample concentrations.
Sample concentrations were calculated by XLfit4 software version 2.2.1 Build 16 (Microsoft Corporation, Redmond, WA).
Twofold serial dilutions were made to provide a total of five sample concentrations.
Sample concentrations varied within 100 175 mg of PHA per 100 ml of chloroform.
Sample concentrations were calculated by linear regression analysis using the analyst software 1.5.1.
Extraction recovery of prednisolone was greater than 84% over the range of low to high quality control sample concentrations.
To make chromatographic signals comparable, it is crucial to remove the scaling effect, caused by differences in overall sample concentrations.
These LODs relate to total sample concentrations and are defined according to a definition unique to potentiometric sensors.
All tests were performed in duplicate, averaged and compared to CFAS in order to interpolate sample concentrations.
SHHA and SRHA required higher sample concentrations, and commensurately higher Mg2+concentrations, and clouded at relatively high temperatures.
