Miniaturized Quantum Cascade Lasers Enable Fast Mid-IR Spectroscopy
Quantum cascade lasers have been gaining increasing attention as their capabilities are being demonstrated in a range of applications. One recent advance is the development of a miniaturized QCL, which when used as a light source, enables mid-infrared (mid-IR) scanning speeds much faster than those of conventional Fourier-transform IR (FT-IR). Ralf Ostendorf of the Fraunhofer Institute for Applied Solid State Physics in Freiburg, Germany, recently spoke to Spectroscopy about this work. |

Where Can LIBS Make the Biggest Impact?
For an emergent analytical technique to be adopted, its proponents must find applications where it offers significant benefits over established techniques, such as sensitivity, speed, cost, or ease of use, or some combination of those. For laser-induced breakdown spectroscopy (LIBS), identifying its ideal niche has been one of the challenges in gaining followers. To assess where LIBS is being used today, what new areas are emerging, and how well LIBS competes with other methods in those new areas, we asked a panel of experts for their views. |

Approaches to Maximize Performance and Reduce the Frequency of Routine Maintenance in ICP-MS
The importance of routine maintenance in ICP-MS cannot be overemphasized. The potential for thermal instability, corrosion, chemical attack, blockage, matrix deposits, and signal drift is much higher with ICP-MS than with other atomic spectroscopy techniques. By following the guidelines provided here, however, you can reduce the frequency of routine maintenance and ensure optimal instrument performance. |

The State of the Art of Flow-Through Solid-Phase Spectrometry
Flow-through SPS lowers reagent and sample consumption and decreases waste generation. This technique allows the analyte separation and enrichment by removing possible sample matrix interferences with detection on the surface of the sensor. Therefore, higher sensitivity and selectivity is achieved when comparing this technique with other on-line sample pretreatment techniques. |
