Elemental Analysis Through a Plastic Barrier
By Jim Hardy , Bruce Scruggs, PhD , Edax, Inc. , Ametek
Demonstration of the advantages of using the Orbis micro-XRF elemental analyzer rather than other analysis techniques to perform elemental analysis through a plastic barrier and/or at atmospheric pressure.
Single Reaction Chamber Microwave Digestion of Highly Organic Matrices
By David Gunn , Milestone Inc.
Sample matrices with high organic content have created a significant challenge for sample preparation methods.
Moxtek's MXDPP-50: X-ray Detection Performance Characterizations
By Sterling Cornaby , Moxtek
Moxtek now has a full energy dispersive X-ray fluorescence detector solution with Moxtek's XPIN detectors and our new MXDPP-50 electronics.
Analysis of Additive Elements in Polymer Using ZSX Primus Series/Application Package
By Rigaku Corporation
This application note introduces an Application Package for quantitative analysis of additive elements in polymer.
Savillex C400d: A New General Purpose, Inert Nebulizer for ICP-MS
By Don Potter , Greg Eiden , Savillex Corporation
The new Savillex C400d PFA concentric nebulizer for ICP-MS combines the reliability of a low flow glass nebulizer with the chemical resistance and low elemental background of a PFA concentric nebulizer.
Handheld Laser-Induced Breakdown Spectrometer for In-field Elemental Analysis
By David Day, PhD , Don Sackett, PhD , SciAps, Inc.
SciAps has developed a handheld analyzer based on laser induced breakdown spectroscopy (LIBS).
US EPA SW-846 Method 6010C Using the Prodigy7 High-Dispersion ICP Introduction
By Manuel Almeida , Teledyne Leeman Labs
This application note describes the capability of the Teledyne Leeman Lab's Prodigy7 High-Dispersion ICP for performing analysis according to SW-846 Method 6010C.

Determination of Low Concentration Methanol in Alcohol by an Affordable High Sensitivity Raman Instrument
By Duyen Nguyen , Eric Wu , Enwave Optronics
Low concentration natural methanol exists in most alcoholic beverages and usually causes no immediate health threat.
Depth Profiling of Complex Samples Using Confocal Raman Microscopy
By Thomas J. Tague, Jr. , Bruker Optics, Inc.
Raman microscopy has evolved into a common method for fast and nondestructive analysis of microscopic samples in forensic and R&D laboratories as well as for troubleshooting in the field of quality control.
Thermally-Induced Structural Changes in Proteins Measured by ATR Spectroscopy
By S.L. Berets , Harrick Scientific Products, Inc.
Infrared ATR spectroscopy has recently gained recognition as a viable technique for protein structural analysis due to its high information content, rapid sampling rate, and minimal sample preparation.
Characterization of Diesel Fuel Using a Modular Raman System
By Yvette Mattley, PhD , Ocean Optics, Inc.
Raman spectroscopy is an excellent technique for the identification and characterization of fuels. With no requirement for sample preparation and the power to identify and quantify materials, Raman has many uses across a range of industries.
Investigating Polymer Orientation with FTIR-ATR
By Jenni L. Briggs, Ph.D , PIKE Technologies, Inc.
Polymer orientation of a blow-molded plastic was investigated using FTIR-ATR with polarization. By using a variable angle ATR accessory, changes in spectral features were observed at two different probing depths.
Highest Spectral and Spatial Resolution for Chemical Imaging
By WITec GmbH
Raman microscopy is a high resolution imaging technique that has become widely used for the characterization of materials in terms of their chemical composition.
The Use of Raman Spectroscopy in Cancer Diagnostics
By Robert Thomas , Katherine A. Bakeev , Michael Claybourn , Robert Chimenti
Both Raman spectroscopy and surface-enhanced Raman spectroscopy (SERS) are proving to be invaluable tools in the field of biomedical research and clinical diagnostics.
A Rapid FT-IR-Based Method for Monitoring Detergent Removal from Biological Samples
By Ivona Strug , Sara Gutierrez , Amedeo Cappione III , Mary Jane Mullen , Timothy Nadler
In life science research, detergents are primarily used in sample preparation to liberate cellular components through membrane disruption and to solubilize lipid-associated proteins.
