摘要： The invention provides a multi-inlet sampling device for an ion source. In general, the sampling device contains at least two sample inlet capillaries and a single outlet capillary that are all fluidically connected. A mass spectrometer ion source and a mass spectrometer system containing the multi-inlet sampling device are also provided. The device is readily removed and installed at ambient pressure without venting the mass spectrometer. Also provided by the invention are methods for simultaneously introducing at least two samples into a mass analyzer.
