The electromagnetic spectrum, from radio waves to gamma rays, provides numerous “windows” through which to examine the world. Each band of frequencies offers different kinds of information that can be used for science and technology. At the border between radio waves and infrared light lies the extremely high frequency (EHF) band of radio waves. These […]

Raman spectroscopy is a young analytical technique, but has rapidly become a standardized analytical tool in both lab and industrial applications. More recently, demand for portable Raman spectroscopy has exploded due to technological improvements. While security applications remain the central area of demand, portable Raman spectroscopy is expanding into other areas. Raman is useful for […]

Ultrasonic homogenizers use ultrasonic sound waves to create cavitation, which is the rapid formation and collapse of minute bubbles. These imploding bubbles vibrate violently, creating mechanical waves that disrupt the surrounding cells/particles. Ultrasonic homogenizers are heavily used in life sciences laboratories to disrupt cells and tissues. Applications include tissue preparation, nucleic acid extraction and the […]

The metals industry makes use of a number of specialized analytical tools to determine the composition of samples. While arc/spark optical emission spectroscopy is probably the technique that is most associated with metals analysis, dedicated inorganic combustion analyzers are also heavily in demand. These instruments typically measure a small number of individual elements. Some metal […]

MS technology has continued to advance at a rapid pace. While advanced lab-based MS applications receive the majority of attention, portable and in-field MS has grown as well. Technological improvements over the past decade have allowed the portable and in-field MS market to blossom, leading to strong demand from several industries. Rapid technological development has […]

Autoclaves are found in many industrial and scientific labs where the sterilization of materials is required to ensure products are free of microorganisms and bacteria. Autoclaves are used to sterilize liquids, reagents, cell culture media, lab equipment and glassware. They are also used to decontaminate laboratory waste prior to disposal. Autoclaves employ the rather simple […]

Within the field of physical testing, there is a fairly wide range of specific instruments devoted to particular measurements of the strength, hardness or other physical characteristics of materials and components. At the most theoretical level, physical testing involves the application of a stress, and the measurement of the resultant strain on the sample. In […]

The environmental market for process Total Organic Carbon (TOC) instruments is substantial, and is expected to continue to experience robust growth in the near future. There are several traditional analytical methods for TOC analysis, although actions by the US EPA have now allow for much more rapid innovation. The same technology employed in laboratory TOC […]

Water, the most commonly used reagent/solvent, is one of the simplest compounds, yet it is also one of the most complex. There are many different types of contaminants found in water: inorganics, like magnesium and calcium; microorganisms; and suspended particles. Many techniques are used to remove impurities from water. The oldest and most basic method […]

Like several related surface analysis techniques, Electron Spectroscopy for Chemical Analysis (ESCA) provides information about the composition of surfaces by probing the interaction of the samples with various types of radiation. In ESCA, a beam of energetic X-rays irradiates the surface, while detectors measure the energies of the electrons ejected by the high-energy X-ray photons. […]
