Abstract
A miniature mass spectrometry based on a rectilinear geometry ion trap (RIT) and electron ionization (EI) has been built, and its operating parameters have been optimized. The internal volume of miniature RIT is only 3.5 cm 3, and an EI was used as external ionization source. Direct leak introduction inlet systems were used for sample introduction, and the sample pressure keeps about 10-5 Pa. Lab-made electronic components include the radio frequency (RF) scanning and amplification system, current amplifier and lens power supplies. A NI card and Labview software were employed as data acquisition and control components. Some samples such as carbon tetrachloride, tetrachloroethylene and perfluorotributylamine have been tested with some good results.
