Analysis of Total Phosphorus in Water Samples
By Luis Moreno, Hitachi High Technologies America, Inc.
Phosphorus analysis in water is critical for general water quality assessments. This note demonstrates the analysis of total phosphorus in waste water using a UV-Vis spectrophotometer and total phosphorus reagent kit.
Molecular
Spectroscopy of Individual Pixels of OLED Microdisplays
By Paul Martin, CRAIC Technologies, Inc.
Colorimetry and luminous intensity of the smallest pixels can be measured with a UV-visible-NIR microspectrophotometer quickly, easily and with no sample contact.
 
Raman Analysis of Low Concentration Ions in Water
By Duyen Nguyen and Eric Wu, Enwave Optronics, Inc.
We demonstrated the quantitative analysis of low concentration sulfate ion in aqueous solution down to as low as 2.5 ppm by conventional (Non-SERS) Raman spectroscopy.
 
Mapping Protein Conformational Stability Using Automated CD
By Lindsay Cole and David Gregson, Applied Photophysics Limited
A new automated technique is described for measuring protein conformation. Superb reproducibility enables relative protein stabilities to be studied with ease, for example in protein biotherapeutic development and clone selection procedures.
 
Real-Time Monitoring of Tablet Film Thickness in a Fluid-Bed Coater Using FT-NIR
By Frederic Despagne and Prof. Guang-Jin Choi, ABB Analytical Measurement
FT-NIR spectroscopy to perform real-time monitoring of the tablet coating process. It is a fast and nondestructive technique particularly adapted for in-line determination of formulations critical quality attributes during pharmaceutical unit operations.
 
Quantitation Limit of Pharmaceuticals Determined by UV-Vis
By Shimadzu
Cleaning validation is essential in order to prevent contamination of pharmaceutical products. Introduced here is the determination of the quantitation limit for the Shimadzu UV-1800 spectrophotometer by absorption photometry.
