Featured Application Note:
FT-NIR — Fast and Effective for Controlling Critical QC Parameters in the Sugar Industry
Hui Li, Bruker Optics, Inc.
Bruker’s FT-NIR system was used in this study to monitor critical QC parameters in all steps of processing sugar cane.

	Identification of CCA Contamination Using NIR Spectroscopy *Yvette Mattley, PhD and Derek Guenther, Ocean Optics* NIR spectroscopy is a powerful technique for analyzing chemical composition. In this application we used a 512-element InGaAs array spectrometer to identify a contaminant affecting circuit card assembly performance.
	Environmentally Friendly Oil in Water Analysis by FT-IR Spectroscopy, Based on ASTM 7678-11 *Frank Higgins, Agilent Technologies* This app note demonstrates oil in water analysis based on ASTM D7678-11 using the Agilent Cary 630, 4500, and 5500 series FT-IR. These spectrometers are ideal for onsite use in oil depots, refineries, offshore rigs, and environmental remediation sites.
	FT-IR Analysis of Dimethicone Based on USP-Specified Method *Shimadzu Scientific Instruments* When analyzing viscous solutions by FT-IR spectroscopy, the ATR method is particularly effective because the close contact between the sample and prism is easily achieved. This application illustrates an example with the analysis of dimethicone, with good repeatability clearly obtained.

	Analysis of Heavy Metals in Soils *PANalytical* Simple sample preparation (pressed pellet) and unique power envelope for excellent sensitivity make XRF the method of choice for analyzing heavy metals in soils in accordance with regulations, that is EU Directive 86/278/EEC.
	Syringe-Driven Sample Introduction for ICP Spectrometry *Ryan Brennan, Jerry Dulude, and Scott Bridger, Glass Expansion* Systems with one, two, or three syringe drives in concert with a custom switching valve are described. Benefits include improved accuracy, precision, and speed.
	The Accurate Measurement of Selenium in 12 Diverse Reference Materials Using On-Line Isotope Dilution with New Triple Quadrupole ICP-MS Technology *Naoki Sugiyama, Agilent Technologies* Until now, it has been difficult to accurately measure selenium (Se) at ultra-trace levels in high matrix samples. The new Agilent 8800 ICP Triple Quad is able to remove all interferences on the three major Se isotopes, giving accurate Se measurement regardless of sample type.
