Measuring Current per Second of Low Volatility Organics by using Simple KEMS (Knudsen Effusion Mass Spectrometer) System and Quadrupole Mass Spectrometer

In order to calculate the thermo chemical properties of the low volatile organic and inorganic compounds, specifically in the gas phase, it is essential to have sufficient knowledge about the vapourisation or sublimation. The present research work is intended to examine and analyse the current per second of the low volatility organics and inorganics. In this account, a simple KEMS as well as the quadrupole mass spectrometer is being used. The research has developed the hypothesis which states that current per second, i.e., ln(cps)vs1/T is similar to the ln(pressure)vs1/T. In order to verify this hypothesis the research has included the experimental analysis of the selected low volatility organic and inorganic compounds, i.e., phenol and iodine. The experimental study has acquired the values of enthalpy for phenol and iodine, which are found to beand, respectively.
