Kwansei Gakuin University in Hyogo, Japan, Uses Raman Microscopy
Raman Microscopy study crystallographic defects in silicon carbide wafers.
Structural Discoveries Could Aid in Better Drug Design
Scientists have uncovered the structural details of how some proteins interact to turn two different signals into a single integrated output.
X-ray Laser Experiment Could Help in Designing Drugs for Brain Disorders
Scientists found that when two protein structures in the brain join up, they act as an amplifier for a slight increase in calcium concentration, triggering a gunshot-like release of neurotransmitters from one neuron to another.
Team Identifies Structure of Tumor-Suppressing Protein
An international group of researchers led by Carnegie Mellon University physicists Mathias Lösche and Frank Heinrich have established the structure of an important tumor suppressing protein, PTEN.
Major Innovation in Molecular Imaging Delivers Spatial and Spectral Info Simultaneously
Berkeley Lab scientist invents technique to combine spectroscopy with super-resolution microscopy, enabling new ways to examine cell structures and study diseases.
Helicobacter Pylori's Secret Weapon
Finding the molecular interactions that make this pathogen so successful in such a harsh environment has, until now, proved elusive.
Unprecedented Insights Into the Reactions Powering Fuel Cells
Nanotech-enabled chip developed at UCLA can analyze chemical reactions more accurately than large machines
Ultrafast Laser Pulses for Spectroscopy and Biomedical Applications
Graphene Flagship researchers have developed an optical fibre laser that emits pulses with durations equivalent to just a few wavelengths of the light used. This fastest ever laser based on graphene will be ideal for use in ultrafast spectroscopy, and in surgical lasers that avoid heat damage to living tissue.
Device May Detect Urinary Tract Infections Faster
A Lab-on-a-Disc platform developed by a German and Irish team of researchers dramatically cut the time to detect bacterial species that cause urinary tract infections -- a major cause of sepsis.
New Hybrid Microscope Offers Unparalleled Capabilities
A microscope being developed at the Department of Energy’s Oak Ridge National Laboratory will allow scientists studying biological and synthetic materials to simultaneously observe chemical and physical properties on and beneath the surface.

The Fundamentals of Infrared Spectroscopy

Midac Corporation

Infrared spectroscopy is a technique which measures the infrared absorbances of various materials in gas, liquid, or solid phases using suitable sampling techniques. The infrared spectrum is qualitatively useful in determining the identity of a compound, as all materials have different infrared signatures. The infrared spectrum is also quantitatively useful as the strength of the infrared absorbances vary with concentration. Gas phase measurements using infrared spectroscopy are especially powerful as sample concentrations can be analyzed over 12 orders of magnitude, from parts-per-billion levels up to pure materials where trace impurities are of interest. The technology of infrared gas analysis is very mature and well-established in both industrial and research applications.
