mass spectrum การใช้

• This gives a mass spectrum, or fingerprint, of the sample.
• The mass spectrum was further analyzed by Steven Frautschi.
• The ion will be observed at 45.5 Th in a mass spectrum.
• Sequest identifies each tandem mass spectrum individually.
• A notation has been developed for indicating peptide fragments that arise from a tandem mass spectrum.
• Therefore, the rule is typically only applied to the molecular ion signal in the mass spectrum.
• A forensic standard for this compound is available, and a representative mass spectrum has been posted on Forendex.
• The analytes are sometimes involved in electrochemical processes, leading to shifts of the corresponding peaks in the mass spectrum.
• The candidate sequence with the best matching theoretical tandem mass spectrum is reported as the best identification for this spectrum.
• A mass spectrum is a plot of the ion signal as a function of the mass-to-charge ratio.
• A mass spectrum is recorded at every photon energy, and the fractional ion abundances are plotted to obtain the breakdown diagram.
• A common way to get more quantitative information out of a mass spectrum is to create a standard curve to compare the sample to.
• Co-crystallization is a key issue in selecting a proper matrix to obtain a good quality mass spectrum of the analyte of interest.
• Also, the density of states and the mass spectrum must be asymptotically equivalent in the sense of the weak constraint proposed by Hagedorn as
• Thermal pyrolysis of coronene shows masses of dicoronylene and the condensed trimer, tetramer, and pentamer in the mass spectrum of the black product.
• In a Kendrick mass analysis, the Kendrick mass defect is plotted as function of nominal Kendrick mass for ions observed in a mass spectrum.
• Many reaction pathways exist for fragmentation, but only newly formed cations will show up in the mass spectrum, not radical fragments or neutral fragments.
• Use of mass spectrometry as a second component of an operando experiment allows for optical spectra to be obtained before obtaining a mass spectrum of the analytes.
• User was subject to arbitration related to a content dispute and inappropriate behavior at Mass-to-charge ratio, Thomson ( unit ) and Mass spectrum.
• In halogens on the other hand, higher isotopes have a large abundance which results in a specific mass signature in the mass spectrum of halogen containing compounds.
