What is spectroscopy? What conclusion can be drawn from the fact that two spectra of two different compounds have certain lines at exactly the same wavelengths? Define the terms matter and mass. What determines the color and temperature of a flame?
Near Infrared (NIR) Spectroscopy is an analytical technique used across a wide range of sectors and industries. Click to read more...
Spectroscopy, a field of study that uses light absorption and emission patterns to characterise matter, is divided into a range of specialty areas. Spark Spectroscopy is one of the most useful, with high sensitivity and fast analysis times making it the technique of choice for a variety of ...
Electrode Impedance Spectroscopy Alternating Current Polarography Alternating Current Voltammetry Ultramicroelectrodes References Notes and Definitions Linear diffusion1 Most electrodes can be approximated as having linear diffusion on short time scales. The larger the electrode, and the shorter the time observ...
Compare spectroscopy and mass spectrometry. What types of applications are best suited for each? What is gravimetric analysis? How does the infrared spectrometry machine work and what is it used for? How could one distinguish between ethanol and dimethyl ether using mass spectrometry? What is meant...

In reality, some of the motion is ‘observed’ indirectly in X-ray and cryo-EM structures as a drop in resolution, where structural features are less well-defined due to the ‘blurring’ of features, caused by the motion. On the other hand, NMR spectroscopy, although traditionally limited ...
Explosives trace detection is the process of finding very small amounts of explosives or the ingredients used to make them so that...
Odour that may be released when opening packaging of plastic objects is often a concern for collection managers. Volatile compounds emitted by three separate plastic-coated textile objects from Centraal Museum Utrecht were identified. Samples are analysed with Fourier Transform Infrared Spect...
FTIR spectroscopyis considered to be the ultimate triage technique, because the process is so straightforward and speedy: you basically present the sample, get an answer, and act on it. The sampling for FTIR can be very flexible, since it has the ability to look at gases, liquids or s...
