Spectrophotometers
Ultraviolet-visible (UV-Vis) spectrophotometry is arguably the most common as well as one of the oldest forms of absorption-based analysis. UV and visible regions of the electromagnetic spectrum are contiguous: UV wavelengths range from 10 to 4000 angstroms; they are visible from 4000 to 7000 angstroms.
This application note aim to show that elemental mapping and small spot analysis create new dimensions of investigation in process control, research and development, even at low power with the Thermo Scientific™ ARL™ PERFORM’X WDXRF analyzer 1500 Watt.
This application note from Shimadzu explores use of UV-Vis and FTIR in monitoring and characterizing gold nanoparticles.
Approach tackles newer bullets, eliminates the need for expensive analysis equipment.
From the evolution of handheld spectroscopy arrives Progeny™ - the first handheld Raman analyzer designed to be customizable for seamless integration into any work environment. Constructed for flexibility, this device adapts to evolving workflows, laboratory processes, and new personnel. Progeny raises the standard on what a portable Raman device should provide to lab managers, chemists, scientists, and other lab personnel needing fast and accurate materials analysis.
As FTIR instrumentation has become more compact and reliable, it has experienced a type of commoditization. That does not mean that innovation has ceased.
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.
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.
