There are two main types of spectra. Continuous and line spectra and while these are generally different, it is possible to have both of them. Continuous spectrum can be learnt vividly in the context of light and electromagnetic spectrum. Here is a brief definition and description of these ...
Over the years chromatography has gained an enviable position in analytical laboratories. You have been introduced to simple concepts on how to read a chromatogram.
How would NMR (^1H or ^13C) spectroscopy be used to distinguish between the following pairs of compounds? (IMAGE) Compare spectroscopy and mass spectrometry. What types of applications are best suited for each? What is analytical chemistry?
The simplest, and most commonly used, type of multiplexing is duplexing, in which two genes are amplified in a single reaction. Typically, in a relative qPCR experiment designed to determine the fold change differences in gene expression, these will be a single gene...
what are the internalizing and externalizing spectra? the notion of a latent underlying dimensional spectrum may seem somewhat abstract on first reading. consider, for example, part b in the figure of kessler et al. this elegant model fits the data better than the more complicated model shown ...
Their push to define the technology was informed by the needs of producers working with Melodyne. Now available directly insidePro Tools, ARA2-enabled Melodyne brings together two of the most powerful pro applications in the industry. Gone are the days of capturing audio from the timeline to the...
NAS stands out for its ease of access, high capacity and low cost. The devices consolidate storage in one place and support a cloud tier and tasks, such as archiving and backup. Network-attached storage and storage area networks (SANs) are the two main types of networked storage. NAS handl...
This is illustrated in the two FFT (Fast Fourier Transform) spectra below. The two pictures are showing that the harmonic components are shifted in frequency when the rotation speed changes: FFT spectrum indicates the measured vibration of a machine running with 2946 RPM. The first 10 harmonics ...
The resonant frequency depends on both the environment that the nuclei are in (e.g. how many and which atoms they are close to), and the magnitude of the applied magnetic field. The intensity of the NMR signal is proportional to the number of nuclei within each resonant frequency. This is...
For example the monochromators used in the Edinburgh Instruments FS5 and FLS1000 are a more complicated Czerny-Turner design which have two slits and two ellipsoidal mirrors for superior performance but the principle remains the same. Types of Optical Spectrometer Now that the key component of a ...
