A Reflectance Flow-through Thionine Sol-gel Sensor for the Determination of Se(IV)
Reflectance Flow-through Thionine Sol-gel Sensor Determination of Se
2010/9/13
In this work, a reversible sensor to assess the total Se(IV) content in samples is described. Pre-activated glass slides were spin-coated with 100 μL of a 20-h aged sol-gel mixture of 1 mL of tetrame...
Quantitative Spot-Test Analysis of Metformin in Pharmaceutical Preparations Using Ultraviolet-Visible Diffuse Reflectance Spectroscopy
Quantitative Spot-Test Analysis Metformin Pharmaceutical Ultraviolet-Visible Diffuse Reflectance Spectroscopy
2010/9/17
A quantitative spot-test for the determination of metformin in pharmaceutical preparations using diffuse UV-visible reflectance is reported. The procedure is quite simple, involving in the formation o...
Radiometric Cross Calibration of AVNIR-2 and MODIS Using Directional Functions of Top-of-Atmosphere Reflectance
ALOS AVNIR-2 radiometric calibration MODIS
2009/3/19
An effective cross-calibration scheme is proposed and used for evaluation of AVNIR-2 radiometric accuracy. The scheme uses top-of-atmosphere reflectance functions of satellite zenith angle at each sam...
A Semiautomated Reflectance Colorimetric Method for the Determination of Lipase Activity in Milk
Pseudomonas lipase milk quality psychrotroph
2008/3/26
Measurement of heat-stable lipase activity in dairy products relies on methods that are slow or that cannot be used in turbid solutions, which limits their industrial value. A need exists for a rapid,...
