Thermal decomposition provides valuable information about the chemical composition of a material. Although thermal gravimetric analysis (TGA) measures small weight losses during a heating ramp, it cannot identify the chemicals corresponding to the weight loss.

Used everywhere from bar code scanners to sophisticated single-molecule microscopes, lasers are powerful and cost-effective light sources for applications spanning basic research to consumer entertainment.

The new Savillex PFA Cyclonic Spray Chamber is the first inert chamber with the traditional shape of a glass cyclonic, and is also the first translucent inert chamber.

Ancient Roman builders designed maritime concrete harbor structures to remain intact in the aggressive seawater environment for very long periods of time.

Milestone's UltraWAVE microwave digestion system with single reaction chamber (SRC) technology, enables the simultaneous digestion of up of to 22 different sample types and chemistries at temperatures and pressures as high as 300 ?C and 199 bar.

The permitted sulfur limit in fuel oils has been decreased to 10 ppm in many regions.

When images are measured in reflectance, the observed structure is not necessarily just that of the sample surface.

Grazing angle Ge ATR spectroscopy is extremely sensitive to monolayers and thin films on high refractive index substrates such as Si.

A broadband polarizing beamsplitter (PBS) cube was developed using embedded Moxtek Nanowire grid polarizer technology.

What if the decisions neurosurgeons make during surgery - such as about how much tissue to remove - could be guided by immediate results from spectroscopic methods? A number of spectroscopy researchers are seeking to advance methods to make that both possible and practical.

Raman measurement on microscopic inclusions in fluorescent materials requires the ability to measure in small volumes, excellent throughput, and long wavelength excitation such as 1064 nm for fluorescence reduction.

The thermal treatment of a grafted Sn-SiO2 catalyst was monitored in situ using diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS).

The "inelastic scattering of light," or Raman effect, was observed in practice for the first time in 1928 by C.V. Raman for which he was awarded the Nobel Prize in 1930.

A method for quantifying the percent sulfate associated with sodium lauryl sulfate (also referred to as sodium dodecyl sulfate) and sodium laureth sulfate (also referred to as sodium lauryl ether sulfate) found in commonly used commercial body care products using FT-IR attenuated total reflectance (ATR) spectroscopy is outlined.

Newly developed software tools provide various functions for the acquisition, evaluation, and processing for high-resolution 3D Raman images.

Bruker's IFS 125HR spectrometer is designed as an ultra-high resolution FT-IR spectrometer which provides outstanding performance for R&D laboratory application.

Luminescence materials are important for modern technology because of their ability to convert electromagnetic radiation (that is, ultraviolet [UV] and infrared [IR] light) into visible light (1).

The lanthanide series is a series of metallic elements, with atomic numbers 58 through 71, which are - in order of increasing atomic number - cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium.
