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 کاملDiffuse Reflectance Infrared Fourier Transform Spectroscopy for the Determination of Asbestos Species in Bulk Building Materials
Diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy is a well-known technique for thin film characterization. Since all asbestos species exhibit intense adsorptions peaks in the 4000-400 cm-1 region of the infrared spectrum, a quantitative analysis of asbestos in bulk samples by DRIFT is possible. In this work, different quantitative analytical procedures have been used to quant...
متن کاملDIFFUSE REFLECTANCE MEASUREMENTS FROM DIFFERENT SURFACES
Relative diffuse reflection measurements from the original and ground surfaces using a He-Ne laser are reported. The intensity measurements for the metallic, transparent dielectric, matte plastic surfaces and colored papers are presented. Our results indicate that among metallic surfaces tested, aluminum has the highest diffuse reflectance; while the original stainless steel surface shows the l...
متن کاملIndirect determination of molecular chlorine by fourier transform infrared spectrometry.
Nowadays, Fourier transform infrared (FT-IR) spectrometry (both extractive and open-path techniques) is widely used for the detection of air pollutants because the method is fast, reliable, and nondestructive. It is capable of detecting simultaneously all compounds except non-infrared active homonuclear diatomic molecules. Molecular chlorine gas has many anthropogenic sources, including water t...
