Determination of hydrochlorothiazide in pharmaceutical formulations by diffuse reflectance spectroscopy
This paper describes a method for quantitative spot test analysis of hydrochlorothiazide using diffuse reflectance spectroscopy. The reflectance measurements were performed analyzing the colored compound (l = 585 nm) produced from the reaction between hydrochlorothiazide and pdimethylaminocinnamaldehyde (PDAC) in acid medium. This reaction occurred on filter paper after heating to 80oC for 8 mi...
متن کاملDiffuse reflectance spectrophotometry for skin phototype determination.
BACKGROUND The Fitzpatrick skin phototype classification scheme has become the standard method for assessing the reaction of the skin to solar stimuli; this method can be easily biased by different factors, such as ethnicity or chronic sun exposure. METHODS Diffuse reflectance spectrophotometry (DRS) is an objective and non-invasive method used in this work to determine constitutive skin colo...
متن کاملQuantitative Diffuse Reflectance Spectroscopy
In the field of biomedical optics, diffuse reflectance spectroscopy (DRS) is a frequently used technique for obtaining information about the optical properties of the medium under investigation. The method utilizes spectral difference between incident and backscattered light intensity for quantifying the underlying absorption and scattering processes that affects the light-medium interaction. I...
متن کاملDiffuse Reflectance Spectroscopy
The appearance of a soil results from the interaction of its different constituents with incident light. Color and various other attributes of the appearance of soil are highly sensitive to the nature, proportion, particle size and morphology, and spatial association of its mineral and organic components. In fact, color has been used for more than 75 yr to obtain information about these soil pr...
