Computer Aided Design and Analysis of Volatile Separating Device

摘要

Volatiles in the current context are molecules with boiling point up to 200OC. Conventional methods for separating volatiles are biased towards one of the physical or chemical properties of the molecule and hence are not complete. So volatiles separated from the mother matrix will contain fewer molecules and even the most precise instruments can resolve only fewer molecules. On the other hand a better sampling device utilizing thermal desorption, kinetic desorption, solubility in steam, desorption by microwave, desorption by magnetic induction or laser can separate larger number of molecules and hence can enhance the efficiency of instruments like MS. A sampler using thermo-kinetic desorption was fabricated in house and comparative study was conducted against conventional techniques. A 25 percent increase in peaks was observed when analysed with GC. The possibility of thermal decomposition was ruled out by conducting GC- MS studies.The aim of the current study is to develop a highly precise sampling device with global standards and has wide applications in the field of aromatic, analytical, biological and medical fields.
