| Total-Reflection X-Ray Fluorescence Analysis (TXRF) as a Powerful and Cost Competitive Technique for Surface Chemical and Trace Element Analyses |
|
Total-reflection X-Ray fluorescence analysis (TXRF) and grazing-incidence XRF (GIXRF) may be applied for surface and bulk trace element analysis of thin-layered systems. Burkhard Beckhoff of the Physikalisch-Technische Bundesanstalt in Germany spoke to us about his recent work in this field.

| Development of an Analytical Method to Determine Chromium, Iron, Nickel, and Zinc in Mouthwash by ICP-OES and Assessment of Possible Metal Migration from Stainless Steel |
|
Simple analytical method, requiring no sample pretreatment, was developed for determination of chromium, iron, nickel, and zinc in mouthwash by inductively coupled plasma‒optical emission spectrometry (ICP-OES). This method allowed the study of potential migration by iron, chromium, and nickel from stainless steel containers.

| Quantum Cascade Laser Infrared Microscopy and 2D IR Correlation Spectroscopy Improves Crystallization Screening of a Protein Complex |
|
Well-diffracting crystals are essential for X-ray diffraction of crystallized protein for structural determination. A quantum cascade laser (QCL) infrared microscope is used to determine protein aggregation, distinct from self-association, for the success of the crystallization effort.

Techniques for Improved ICP-MS and ICP-OES Analysis
The increasing demand for lower and lower detection limits is a major consideration for most laboratories. The development of sophisticated instrumentation, such as ICP-OES and ICP-MS, provides the capability to achieve limits of detection previously unobtainable by other atomic spectroscopy techniques.
