The PowerWave microplate spectrophotometers combine a monochromator-based optical system with hardware and software features designed to meet a variety of microplate-based applications. The readers allow the user to either scan across selected wavelengths or select a discrete wavelength (in 1 nm increments) across the UV-Vis range.
Scientists at the US Department of Energy's Argonne National Laboratory have devised a 'next generation' X-ray light source — the free electron laser oscillator (X-FELO) — that is many times brighter than current X-ray technologies.
Researchers at the National Institute of Standards and Technology (NIST) have built a system that relies on the ‘noise’ of jiggling electrons as a basis for measuring temperatures with extreme precision. The system may help define the Kelvin.
As a tool, conventional mass spectrometry is a good method for differentiating between proteins with different masses. However, as different folded forms of a particular protein have identical masses, it is virtually impossible to differentiate them by conventional means. That's where the Waters Synapt HDMS system and its embedded ion mobility technology can help.
Dietary fibre including cellulose, hemicelluloses, lignin, pectin, rubbers and waxes can be determined by digestion with thermostable enzymes in foods and animal feeds. AOAC International (Official Methods of Analysis) has proposed enzymatic method 985.29.
Physicists at NIST-Boulder have carried out a powerful new spectroscopic study of a gas sample using optical frequency combs.
