We have developed a new detector that achieves high sensitivity and multi-purpose properties for liquid chromatographs using ion mobility spectrometry. Characterized by rapid separation capability of separating ions on the basis of their sizes and structures, it is expected to be used for analyzing a wide variety of samples. Measurements were performed in order to evaluate sensitivity and resolution of the new instrument, and sensitivity of 30 pg in caffeine detection and resolution of 70 for sucrose by the ion mobility spectrometer were achieved. It is also capable of detecting a wide range of compounds with high sensitivity.
