	UV-Vis Performance Validation Software for Improved GLP/GMP Support *Shimadzu Scientific Instruments* Conducting instrument validation manually is a cumbersome task. This paper presents software that makes it easy to conduct an entire series of regulation and standards-related operations, from the setting of validation conditions to data measurement, pass/fail judgment, and file storage.
	Polymer Film Making for FT-IR Transmission Analysis *Jenni L. Briggs, PhD, PIKE Technologies* Infrared transmission measurements of polymers allow for additives and other low concentration components. This note presents a real-world application of silane-grafted polyethylene films, which requires polymer film making.
	Advantages of TE Cooling for Raman and Fluorescence *B&W Tek, Inc.* In this application note we demonstrate the benefits of a TE cooled spectrometer by comparing the technology with a non-cooled device, configured for both fluorescence and Raman spectroscopy.
	Long-Wave Dispersive 785 nm Raman: H₂O₂ Quantification *Jack Qian, Lin Chandler, and Eric Bergles, BaySpec, Inc.* Qualitative and quantitative measurements of H₂O₂ concentration in unknown samples are observed with an error of ± 0.1% using long wavelength dispersive 785 nm bench-top raman instrument.
	Determination of Low Concentration Methanol in Alcohol by an Affordable High Sensitivity Raman Instrument *Duyen Nguyen and Eric Wu, Enwave Optronics, Inc.* Low concentration natural methanol exists in most alcoholic beverages and usually causes no immediate health threat. Nevertheless, it is possible to have natural occurring methanol in beverages with concentration as high as 18 g/L of ethanol.

	EDXRF Application Note: Silver in Barite Ore *Scott Fess, Applied Rigaku Corporation* The measurement of silver (Ag) as well as iron (Fe), zinc (Zn), and lead (Pb) in barite (BaSO4) concentrates and final tails is demonstrated using the empirical method with the Rigaku NEX QC EDXRF elemental analyzer.
	Gourmet Salt Analysis for Presence of Heavy Metals *Patricia Atkins, SPEX CertiPrep* This study examined a variety of gourmet salts, spanning many different colors, production methods, textures, and price points, for elemental composition and for the presence of heavy metals.
	Multi-Element Determination in Food Samples *Simon Lofthouse, Thermo Fisher Scientific* Learn how simultaneous determination of trace-level contaminants and macro-level nutrients in food can be efficiently and rapidly performed using the latest quadrupole ICP-MS technology.

Drinking Water by U.S. EPA 200.8 with NexION 300X
Ewa Pruszkowski, PhD and Cynthia P. Bosnak , PerkinElmer, Inc.
This work describes a method using both standard and collision modes in a NexION 300X ICP-MS, in anticipation of Method 200.8 allowing the use of collision/reaction cell technology for drinking water.
