Featured Application Note:
Sample Preparation Free Micro ATR FTIR Imaging of Polymer Laminates
Dr. Mustafa Kansiz, Agilent Technologies
This note presents a unique nondestructive method of ultralow pressure micro ATR FTIR chemical imaging that allows delicate and thin samples to be measured “as-is” using direct contact with the ATR crystal.

	Automated Comparison of Circular Dichroism Spectra of Proteins *Lindsay Cole, Applied Photophysics Limited* Automated sample handling and data processing were used to compare circular dichroism spectra of eight mammalian serum albumins. Very slight differences were identified using statistical analysis and two normalization techniques.
	Transmission Grating Based Spectrometers *Thomas Rasmussen, Ibsen Photonics* Learn about the important benefits that compact spectrometers based on transmission gratings can provide. The highest possible throughput, flexibility for OEM integrators, and a robust athermal design for industrial applications.
	Magneto-PL Unveils Photoluminescence in Si Nanocrystals *Gerald Cairns, Andor Technology* The emitting properties of nano-structured silicon (Si) are investigated by spectroscopic magneto-photoluminescence (magneto-PL), in the quest for all silicon-based, more compact and further integratable photonic devices.

	Ca Analysis by Atomic Absorption *Shimadzu* Supplements/functional foods that maintain the Ca balance in the body are continuously being developed. This application note presents a type of interference that may occur in flame analysis of Ca, and an effective corrective action.
	Analysis of Trace Metals in Foods Using the Agilent 7700x ICP-MS *Steve Wilbur, Agilent Technologies* The Agilent 7700x ICP-MS can accurately analyze a variety of foods for metals at trace and major levels using a single collision cell method. This provides a rapid, sensitive, and cost-effective screening test.
	RoHS II/WEEE/ELV Analysis of Polyolefins by ASTM F2617-08 *PANalytical, Inc.* XRF is an optimal solution for the detection and quantification of toxic heavy metals in polyolefins, in accordance with the EU directives RoHS II, WEEE, and ELV.

Microwave Digestion of Food Samples With Single Reaction Chamber Technology
Tim Michel, Milestone Inc.
Single reaction chamber (SRC) microwave digestion technology can replace closed and open vessel digestion, offering higher pressure capability, with higher sample weight capability for the detection of trace metals in food samples.
