Whether its typical samples are liquids, solids, or gases, nearly every laboratory has an ultraviolet-visible spectrometer that serves as a workhorse for dozens of applications.
The market for high-temperature ovens, operating between around 400ºC and 600ºC, is heating up, says Scott Miller, marketing manager at Carbolite (Watertown, WI).
Controls make up some of the most obvious advances
The expanded features in today’s pH meters reflect the broad use of this technology. Researchers use pH meters in a wide range of research fields—including biological and chemical, agricultural and environmental, and more—and virtually all kinds of manufacturing.
Cell Culture and other laboratories that isolate and work with cells require the tools to safely and effectively remove wash and culture media away without harming their cells, and maintaining a safe laboratory environment. The new BVC fluid aspirators are third-generation systems that provide fine control, while providing the highest level of safety.
Refractometers come in all sizes, shapes, capabilities, and prices. Some readers may recognize refractometry as a “high school” analysis method or a specialized technique for measuring specific analytes like sugar in water. Increasingly, lab and process engineers employ refractometry to provide quick measures of key quality attributes that under normal circumstances would require much lengthier assays on significantly more expensive equipment.
Fourier transform infrared (FTIR) spectroscopy, a subset of infrared (IR) spectroscopy, uses a mathematical algorithm, Fourier transform, to translate raw infrared data into a spectrum. FTIR is useful for the analysis of organic and inorganic compounds that exhibit changes in polarity as a result of the vibration, spinning, or perturbation of molecular bonds. FTIR methods are common in such industries as foods, materials, chemicals, pharmaceuticals, forensics, and others. Advantages of FTIR over conventional IR are higher resolution, better signal-to-noise, easier analysis of very small samples and poorly-absorbing species, and much more rapid analysis.
Atomic absorption (AA) has been known since the 19th century, but it was not until the 1950s, thanks to efforts by Alan Walsh at Australia’s CSIRO research center, that use of AA spectrometers became routine for metals analysis.
