    • A combination electrospray/microwave induced plasma (MIP) ionization source is used as the ionization source for a mass spectrometer. The electrospray can be operated in positive mode, negative mode, or it can be switched off. The microwave-induced plasma can also be switched on or off. This allows the instrument to be operated in multiple modes. With the electrospray off and the MIP on, the instrument will normally have its maximum elemental sensitivity. Mixed mode operation potentially allows the determination of additional information about the chemical constituents present in the analyte. In pure electrospray mode, it is possible to obtain molecular information and to analyze organic compounds.
    • 组合电喷雾/微波诱导等离子体(MIP)电离源被用作质谱仪的电离源。 电喷雾可以在正模式,负模式下操作,也可以关闭。 微波感应等离子体也可以打开或关闭。 这允许仪器在多种模式下操作。 当电喷雾和MIP打开时,仪器通常具有最大的元素灵敏度。 混合模式操作可能允许确定关于分析物中存在的化学成分的附加信息。 在纯电喷雾模式中,可以获得分子信息并分析有机化合物。

    • A system and method for fluid dilution is provided, in one example to be used in conjunction with a chemical analysis tool. In one embodiment, a fluid dilution system includes a supply reservoir including a concentrated fluid, a diluent source including a diluent, and a diluted fluid reservoir operably coupled to the supply reservoir and the diluent source. A fluid level sensor is operably coupled to the diluted fluid reservoir, a pump is operably coupled between the supply reservoir and the diluted fluid reservoir, and a controller is configured to engage the pump based upon signals from the fluid level sensor to pump desired amounts of the concentrated fluid for providing a diluted fluid in the diluted fluid reservoir.
