DST-1000 Acid Purification System
Don Potter, Savillex
The Savillex DST-1000 Acid Purification system produces high purity acid from low cost trace metal grade acid. It can be used to purify HNO3, HCl, and HF. The DST-1000 can pay for itself in a short period of time through the cost savings by using trace metal grade acid instead of bottled high purity acid.

Analysis of Small Samples Using the LUMOS Stand-Alone FT-IR Microscope
Thomas J. Tague, Jr., PhD, Bruker Optics
Fourier transform-infrared (FT-IR) microscopy is a well-established method for the analysis of samples that are too small or complex to be measured in a standard infrared spectrometer.  The new LUMOS stand-alone FT-IR microscope offers a fully automated solution that is very easy-to-use and requires little space.

The MicOS Microscope-Spectrometer: Specially Optimized for Spectroscopy on the Micro Scale
Horiba Scientific
The MicOS, which is a specially designed microspectroscopy instrument, can be used in fields including biology, materials science, and quality control, for examining luminescence of specific spots on a sample, and creating a 2D luminescence map of a surface. MicOS improves signal up to 10 times over standard microscope and spectrometer combinations, plus includes a laser-input port and optics to view the sample downward and side-on.
