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.

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.

SciAps has developed a handheld analyzer based on laser induced breakdown spectroscopy (LIBS).

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.

Raster orbital scanning (ROS) is a technique that dramatically increases the signal-to-noise ratio of Raman measurements made from target materials dispersed on surface enhanced Raman scattering (SERS) substrates.

A new compact instrument (Amphi-Spec) combining dispersive Raman and NIR spectroscopy has been developed at BaySpec, Inc., to deliver maximum analytical power.

Moxtek makes ultra-thin polymer X-ray windows that are often used in SEM and TEM microanalysis detectors.

Even though no current electronics is fast enough to measure femtosecond lasers, an estimation of the pulse duration, peak wavelength, and relative intensity is possible.

Handheld Raman analyzers have found widespread use in the pharmaceutical industry for excipients and raw materials verification, and in first responder/security applications. Most portable Raman units utilize lasers operating at 785 nm because of the relatively good signal strength at this wavelength.

Mercury is a toxic, persistent pollutant found in many native ores rich in copper, silver and gold. As such ores are processed mercury can be released to the environment.

Single reaction chamber microwave digestion enables a chemist to digest up to 15 different specialty chemical samples simultaneously at temperatures as high as 300 ?C, greatly simplifying the workflow while maintaining superior quality digestions.

Yeast suspensions were dried and analyzed via FT-IR using an automated transmission sampling accessory. Up to six-fold sampling capacity increase may be realized through automation.

The analysis of coal is demonstrated, with specific emphasis on the measurement of Na2O, using a Cartesian geometry energy dispersive X-ray fluorescence (EDXRF) spectrometer employing the Fundamental Parameters (FP) approach.

Knowledge of atmospheric ammonia concentrations is important, but ammonia is difficult to measure. We report here on the development of a low-cost ammonia measuring differential optical absorption spectroscopy (DOAS) instrument, based on a small sized and low priced spectrograph.

Low concentration natural methanol exists in most alcoholic beverages and usually causes no immediate health threat.

Pharmaceutical samples spiked with several heavy metals were prepared for ICP-MS analysis using microwave digestion following the protocols in proposed USP chapters <232> and <233>. The results of the spike recovery study are discussed.

Confocal Raman imaging opened the door for many applications in Raman spectroscopy and imaging that were previously unavailable for measurement with conventional (non-confocal) Raman methods.

Owing to technological improvements spurred on by the telecommunications boom of the last decade, Raman spectroscopy has become much more accessible to users in all application areas, including agricultural, forensic, pharmaceutical, biomedical, and others.

Although Raman spectroscopy is an excellent analytical tool, Raman signals are often weak and traditional slit spectrometers typically have poor optical throughput, limiting their effectiveness in low light level setups.

Moxtek's ULTRA-LITE X-ray source is a very small self contained X-ray source (X-ray tube and high voltage power supply) for use in portable X-ray applications, such as the handheld X-ray fluorescence (XRF) spectrometers. This note demonstrates that this X-ray source has a stable and repeatable X-ray flux output over time, which is vital for the precision of the calibrated XRF measurements.

The measurement of trace elements is important across a wide variety of materials characterization problems. When measuring small glass fragments collected from crime and accident scenes, forensics experts analyze trace strontium (Sr) and zirconium (Zr) typically unintentionally incorporated into the glass during manufacturing as one point of identification or comparison.

Multiple reflection ATR is ideal for detecting miniscule levels of components in solutions. If one component is volatile, trace analysis can be simplified by allowing the volatile liquids to evaporate.
