![]() ![]() Under analysis and causes ionization of the atoms or molecule form positive High energy electrons from a heated metal element into the vaporized sample High voltage electron gun falls a beam of In the above diagram the symbol K as sampleĪnd Q as high voltage supply label. The substance which is to be analyzed is injected in the high vacuum tube system which has extremely low pressure particles are ionized through colliding with beam of high speed electron. Deflection mass spectrometer consists of ionization, acceleration the positive ions, which in turn deflection of ions and ion detection followed by deflection, separation and detection. ![]() TheseĪre different types of mass spectrometer: Method No. Mass spectrometer separates and counts the numbers ofĭifferent positive ions particles are released, the resulting product from theĭetector is known as mass spectrum (plural mass spectra). Vacuum and create electron bombardment to generate a beam of positive ionsĬalled ionization. Mass spectrometry is a technique used to determine relative isotopic masses of different elements and relative abundance of the isotopes.Īll types of mass spectroscopy they include vaporing atoms or molecules in high Mass spectrometry is an important method which is used to identify elements and compounds by their mass spectrum. But Cl + ions will pass through the machine and give lines at 35 and 37 it is depend upon isotopes. The Cl atom is neither accelerated nor deflected in the machine it is not ionized in the ionization chamber and simply lost. The ions are not stable so some will formĬhlorine atom and a Cl + ion. Into the ionization chamber, the electrons are knocked off, and give molecular It consist of molecules so when it passed It has two isotopes Cl-35 and Cl-37, so it containģ atoms of Cl-35 and 1 atom of Cl-37. The mass spectrum of ChlorineĬhlorine is such an element which contain more – 37, the weighted average is closer to 35 than 37. Chlorine -35 is about 3 times more abundant than chlorine ![]() Has a relative abundance of 75.76% ,whereas chlorine – 37 has a relativeĪbundance of 24.24%. Different isotopes have different relative abundances ,chlorine – 35 The atomic weight of chlorine given on the periodic table isģ5.47 u. The seven electrons in the third outermost shell acting as its valenceĬhlorine has two stable isotopes: chlorine – 35Īnd chorine – 37. Chlorine hasĮlectronic configuration 3s 23p 5 with Has similar properties like fluorine, bromine and iodine. Chlorine is the second member of halogen group it ![]()
