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.
They have been discovered as part of the PanSTARRs 3π survey, and followed up with the Liverpool Telescope. Based on colours, light curve shape, and a small number with optical spectra, these transients seem to fall into three groups. Red/fast transients are nuclear supernovae of various ...
These clinical samples are difficult to collect and generally only contain a small amount of usable mRNA. In a singleplex relative quantification experiment, only one gene—either the gene of interest or the control—is amplified in each well. Assuming that each assay...
Types of Optical Spectrometer Now that the key component of a spectrometer has been identified, the different types of spectrometer, their role, and basic design can be discussed. Three of the most common optical spectrometers: spectrophotometers, spectrofluorometers and Raman spectrometers are introduce...
Dispersive spectrometers require more expensive detectors but can record spectra significantly faster with no moving parts in wavelength regions where suitable broadband light sources are available.2 Spectrometer equipment on the market today The type of detector often used depends on whether photons or ...

Order spectra of measured vibration from a machine running with 1510 RPM (red) and 2790 RPM (blue). The first 10 order harmonics are indicated with markers, having the same pattern (order positions) for both graphs. With stable vibration patterns across rotation speeds, both manual and automati...
How can spectroscopy be used to identify the presence of specific elements in a substance? In what form (Fe3+ or FeSCN-) could iron be determined by visible spectroscopy? Explain. What are the main differences between Raman and IR spectroscopy?
What are the different types of backup? Businesses have several backup methods to consider, with storage capacity and the length of available backup windows among the factors influencing decisions on which of them to use. As mentioned above, the following are the three primary backup types: ...
Multiparametric segmentation techniques, which require integration of 2 or more MRI sequences, are the newest method.13 In one study,56 for example, proton-density and T2-weighted sequences and T1- and T2-weighted images were combined and used to calculate lesion area.47 These approaches provide...
