    摘要: A mass spectrometer is disclosed comprising a sampling cone and a cone-gas cone wherein, in use, sulphur hexa fluoride (‘SF6’) is supplied as a cone gas to the annulus between the cone-gas cone and the sampling cone in order to improve the transmission of high molecular mass ions passing through the sampling cone into and through subsequent stages of the mass spectrometer.

    摘要: A method of chemical separation includes dispensing a sample from a sample pumping system, pumping a solvent from a solvent gradient pumping system to elute the dispensed sample through a separation column, identifying an analyte of interest in the eluting sample, and pumping a solvent from the sample pumping system for peak parking of the analyte in the separation column.
