In order to carry out a detailed stability study of OXP and CYPZ in combination‚ it is essential to have a single stability-indicating assay method which can separate both drugs along with all of their degradation products from each other. Therefore‚ a RP-HPLC method was developed and optimized. Optimization of the chromatographic conditions In this study‚ the different experimental parameters were carefully studied and optimized in order to improve the performance and system suitability parameters

The purpose of this lab is to measure urinary glucose (a known and unknown sample) using two quantitative tests: colorimetric strip test and o-toluidine test. Urinary glucose is the main focus for this lab due to its involvement with diabetes‚ a disease defined by the abnormal regulation of insulin. The most effective method for monitoring glucose is through blood glucose compared to urinary glucose. It has been discovered that urinary glucose is not a good measure of changes in blood glucose because:
