Parallel plate geometry faims apparatus and method |
摘要 |
A method and an apparatus is disclosed for selectively transmitting ions in which the ions are subjected to a focusing effect such that the overall efficiency of ion transmission is increased. The method relies on a FAIMS analyzer having at least an electrode disposed approximately between two other electrode surfaces for producing an electric field that is symmetric on opposing sides of the at least an electrode. An ion exiting from between the electrodes experiences a balanced electric field, such that impact with one of the electrodes is prevented.
