Atomic
AA Analysis of Cadmium in Chocolate
By Hazel Dickson,Thermo Fisher Scientific
This application note explains the sample preparation procedure and optimized analysis for the accurate detection of cadmium in chocolate using the Thermo Scientific iCE 3500 Atomic Absorption Spectrometer.
 
Improving Si-PIN X-ray Detector Performance
By Shaun Ogden, Derek Hullinger, MOXTEK, Inc.
This application note presents a method was developed for the sequential determination of essential nutrients in soil by using AAnalyst™.
 
Glass, Coatings, Industrial Elemental Analysis with LIBS
By Steven Buckley, Ph.D., Photon Machines, Inc.
LIBS is used for a broad range of elemental analysis (including light elements) with minimal sample preparation. Here we use an example from the glass industry and discuss attributes of LIBS.
 
Retsch Cutting Mill SM 300 for XRF Analysis
By Jacqui Town, Retsch, Inc
The Cutting Mill SM300 grinds difficult samples in one working run. Its high torque, variable speed drive allows for effective size reduction of samples such as electronic components for XRF.
 
The Measurement of Trace Elements in Electrolytic Copper using DC Arc
By Maura Mahar, Paul Dalager, Garry Kunselman, Teledyne Leeman Labs
The Prodigy DC Arc features fast trace element analyses of difficult samples, ease-of-use, and increased productivity for samples found in ceramics such as metal oxides, carbides, borides, and nitrides, as well as refractory powders, geological materials, and more.
Molecular
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.
 
Measuring the Competitive Binding of Diazepam and Ibuprofen to Human Serum Albumin (HSA) using Chirascan™ CD Spectroscopy
By Lindsay Cole and David Gregson, Applied Photophysics Limited
Chirascan™ CD spectroscopy was used to evaluate the binding interactions of two well-characterised small molecule drugs, ibuprofen and diazepam to human serum albumin. Induced CD is a sensitive, label-free method for observing drug-protein interactions in free solution and these studies show the value of using Chirascan™ to further understand the pharmacokinetics of drugs and drug interactions.
 
Confocal Raman Imaging in Life Science - Living Cells, Bacteria & Tissues
By WITec GmbH
This note highlights the potential of Confocal Raman Imaging as a label-free and nondestructive chemical imaging technique with a special focus on single cells in cell cultures, bacteria and tissues.
 
Simplified Spectral Correction for Fluorescence Spectrophotometers
By Luis Moreno, Hitachi High Technologies America, Inc.
Spectral Correction has been simplified via a 4-step procedure and software to perform spectral correction in the full extended range of the instrument, in both the excitation and the emission sides.
 
Wide-field Raman Chemical Imaging: Identification of Drug Forms in Solid Solution
By Dr. Oksana Olkhovyk, ChemImage Corporation
Wide-Field Raman Chemical Imaging is used to provide simultaneous spatial and spectral information that is key to identifying drug forms in solid and semi-solid solutions.
 
Wide-field Raman Chemical Imaging: Characterization of Controlled Release Bead
By Dr. Oksana Olkhovyk, ChemImage Corporation
Wide-Field Raman Chemical Imaging is used to provide simultaneous spatial and spectral information that is key to characterizing controlled release systems and coating thickness.
 
Matching Filters to Fluorophores
for In Vitro Diagnostics
By Gregory Fales, EDMUND OPTICS
Maximizing detection sensitivity and measurement accuracy requires filters to increase the contrast between the fluorophore’s emission and the excitation illumination. Choosing the right filters requires careful selection of wavelength characteristics.
