A simple‚ rapid‚ specific and highly sensitive spectrofluorimetric method has been developed for the quantification of dabigatran etexilate mesylate (DAB) in bulk and capsule dosage form. A linear relationship was found between fluorescence intensity and DAB concentration in the range of 0.01-1.0 μg/ml in DMSO as solvent at an emission wavelength of 391 nm after excitation at 334 nm‚ with a good correlation coefficient (0.989). The detection and quantification limits were found to be 0.005 and 0

From a very young age‚ I can remember sitting at the kitchen counter with my older sisters as my mother was telling us all of the things we needed to do to be upstanding and healthy young adults. As we grew up‚ she continued to preach to us because she didn’t want us to grow up to be misfits.

As a seventeen year old‚ I will admit that I’m the complete opposite

ANALYSIS OF MOUTHWASH Background Information: Commercial mouthwashes are mixtures of water‚ alcohol‚ dyes‚ flavorings‚ and other compounds. In this experiment‚ you will use gas chromatography to determine the alcohol content of the mouthwash. Since the volumes of alcohol and water are not additive when mixed‚ a calibration curve must be used. It will provide the correction factor needed for alcohol-water mixtures. The calibration curve will be prepared by placing a known amount of alcohol
