METHOD AND APPARATUS TO INCREASE THROUGHPUT OF LIQUID CHROMATOGRAPHY-MASS SPECTROMETRY
摘要
An apparatus according to the present invention includes a plurality of sample spraying devices, each of which connects to an LC column. The apparatus includes an electrical circuit that can turn a high voltage between 1 and 5 KV on and off on the time-scale of nanoseconds to milliseconds. The circuit is controlled by a computer program which applies the high voltage to each spray device in a Hadamard sequence. The spray devices are positioned aiming at the mass spectrometer inlet. The preferred configuration of arrangements for the spray devices are in a circle or an arc of a circle around the inlet of a mass spectrometer.
