Control system for mass spectrometer
Abstract
Mass spectrometry (MS) is a very popular analytical methodology that measures the mass-to-charge ratio of ions. It is widely used for determining masses of chemicals, the elemental composition of a sample and molecule structure. The process of mass spectrometry normally consists of ionizing chemical compounds to ions and measuring their mass-to-charge ratios for analysis. MS instruments consist of three modules: Ionization, Analysis and detection. A LabVIEW system is developed to control the three modules of a mass spectrometer, giving the required signals in a right sequence. Experiments can be carried out by using the system very convenient since the software settings are very easy to modify. Broadband radio frequency (RF) circuit is designed. Transformers are tested for the purpose of it, and a good one will be chosen for further test and use. Frequency scan function will be enhanced which will significantly low down the necessary RF voltage.
