In the current data-integrity–centric world, is outsourcing your spectroscopy work a good idea? To answer this question, one must consider several factors.

Nick Stone of the University of Exeter explains why mid-infrared (mid-IR) spectroscopy is so valuable for spectral imaging in disease research and clinical diagnostics, and discusses his own recent work in this area.

LIBS has transitioned from a method found only in research laboratories, to a technique in wide use in commercial settings. Several leading LIBS experts share their views on how the technique has developed and where it is heading.

Mohamad Sabsabi of the National Research Council of Canada explains the fundamentals of LIBS, its recent evolution, and its benefits and limitations, and offers advice for new users.

Raman spectroscopy, using optical tweezers, is capable of measuring the size, refractive index, and chemical composition of single aerosol droplets, at picoliter volumes. This information improves our understanding of molecular-level chemical processes within droplets.
