Spectroscopy Spotlight
The detection, quantitation, and characterization of nanoparticles using inductively coupled plasma–mass spectrometry (ICP-MS), and in particular using single-particle ICP-MS (SP-ICP-MS), has developed significantly in recent years. However, the difficulties involved in this type of analysis vary, depending on the composition of the nanoparticles. Martín Resano of the University of Zaragoza, together with colleagues from Ghent University, has recently developed a method for characterizing nanoparticles made from silicon dioxide (Si02), which are much more challenging to detect than those made from silver or gold. He recently spoke to us about this work. read more

Currently, inductively coupled plasma spectrometry is the most commonly used technique to measure metals within the pharmaceutical industry, and is the recommended technique utilized in the recently updated United States Pharmacopeia chapter on elemental impurity procedures. However, ICP has several drawbacks. Wavelength-dispersive X-ray fluorescence is an alternative technique for elemental analysis used across numerous industries, yet limited literature exists for pharmaceutical applications. read more

Conventional approaches for the assessment of soil mineralogy are primarily based on X-ray diffraction measurements. With this approach the first stage of data analysis involves identification of the minerals present as indicated by the XRD patterns, and a subsequent stage then typically seeks to quantify the relative abundance of the different minerals identified in the soil.

The development of new materials and the assessment of nanomaterials requires the correlation of the materials' functionality or toxicity with their chemical and physical properties. To probe these properties reliably, analytical methods that are both sensitive and traceable at the nano- and microscales are required. read more

For analyzing unknown biological stains in a forensic setting, Fourier transform infrared spectroscopy has many advantages. It can provide confirmatory identification of the fluid type, can estimate the stain's age, discriminate species, and can be used on samples found on various substrates and exposed to various environmental conditions.

Shortwave infrared hyperspectral imaging (SWIR HSI) shows great potential in the targeting and identification of explosive and narcotic materials in complex scenes where the target concentration is low. Tunable filter–based SWIR HSI sensors can be configured to use either single-bandpass or multiple-bandpass wavelength tuning to enable hazardous material detection in stationary, moving sensor, or moving target scenarios.
