Mass spectral interpretation is the method employed to identify the chemical formula, characteristic fragment patterns and possible fragment ions from the mass spectra. [ 1 ][ 2 ] Mass spectra is a plot of relative abundance against mass-to-charge ratio. It is commonly used for the identification of organic compounds from electron ionization ...
A mass spectrum is a histogram plot of intensity vs. mass-to-charge ratio (m/z) in a chemical sample, [1] usually acquired using an instrument called a mass spectrometer. Not all mass spectra of a given substance are the same; for example, some mass spectrometers break the analyte molecules into fragments; others observe the intact molecular ...
It is a type of high-intensity discharge(HID) gas discharge lamp.[1] Developed in the 1960s, they are similar to mercury vapor lamps,[1]but contain additional metal halide compounds in the quartzarc tube, which improve the efficiency and color renditionof the light. The most common metal halide compound used is sodium iodide.
Spectrum (physical sciences) Diagram illustrating the electromagnetic spectrum. In the physical sciences, the term spectrum was introduced first into optics by Isaac Newton in the 17th century, referring to the range of colors observed when white light was dispersed through a prism. [1][2] Soon the term referred to a plot of light intensity or ...
Proprietary. AnalyzerPro is a vendor-independent software application from SpectralWorks for processing mass spectrometry data. It can process both GC-MS and LC-MS data using qualitative and quantitative data processing and is used in metabolomics with MatrixAnalyzer for the comparison of multiple data sets.
Appearance. Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures.
