'Mass Spec Explanation in HTML\r'

'Mass spectrometry bum cooperate determine the molecular(a) formula and heaviness of a compound as swell as provide isotope abundance data. at heart a magnetic field the move of deflection of charged particles is used to ensure the relative masses of molecular fragments and ions. several(prenominal) peaks are due to the contri barelyion of Isotopes. An Isotope refers to an section having the same atomic number scarce a deferent number of neutrons, subtracting or adding mass. The mass spectrum of methyl radical chloride has a ascendent peak at m/z=49 consisting of the most abundant Ion at 100% abundance.It also has a molecular ion peak at m/z=84 consisting of the molecular weight of methyl chloride at 80% abundance. By subtracting the bum peak from the molecular Ion peak, It can be determined that the resulting 35 corresponds to CLC. The difference of separate molecular fragments can be looked at to verify chlorines presence such as and corresponding to the CLC Isotope. The [M*2] rule also Identifies the CLC Isotope when sounding at m/z=84, 86 and 86, 88. Each urn/z peak can represent a variety of diverse molecular mass fragments.The peaks arm=86 and 88 only have and abundance respectively, since both peaks are the results of isotopes. The CLC isotope has a 24% abundance naturally and ICC has a 1% abundance naturally. These low abundance percentages transmit to the smaller intensities of the m/z=86 and 88 peaks. While m/z=86 can be be with only one isotope of CLC, m/z=88 must contain at least two CLC isotopes making the persuasiveness of its peak even less. Mass spectrometry may identify a compounds fragments and isotopes, but it also determines the purities of products.\r\n'
