摘要

An electrospray ionization (ESI)-mass spectrometer analysis systems include an ESI device with at least one emitter configured to electrospray ions and a mass spectrometer in fluid communication with the at least one emitter of the ESI device. The mass spectrometer includes a mass analyzer held in a vacuum chamber. The vacuum chamber is configured to have a high (background/gas) pressure of about 50 mTorr or greater during operation. During operation, the ESI device is configured to either; (a) electrospray ions into a spatial region external to the vacuum chamber and at atmospheric pressure, the spatial extent being adjacent to an inlet device attached to the vacuum chamber, the inlet device intakes the electrosprayed ions external to the vacuum chamber with the mass analyzer and discharges the ions into the vacuum chamber with the mass analyzer; or (b) electrospray ions directly into the vacuum chamber with the mass analyzer.

說明書

It will be understood that when a feature, such as a layer, region or substrate, is referred to as being “on” another feature or element, it can be directly on the other feature or element or intervening features and/or elements may also be present. In contrast, when an element is referred to as being “directly on” another feature or element, there are no intervening elements present. It will also be understood that, when a feature or element is referred to as being “connected”, “attached” or “coupled” to another feature or element, it can be directly connected, attached or coupled to the other element or intervening elements may be present. In contrast, when a feature or element is referred to as being “directly connected”, “directly attached” or “directly coupled” to another element, there are no intervening elements present. Although described or shown with respect to one embodiment, the features so described or shown can apply to other embodiments.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the present application and relevant art and should not be interpreted in an idealized or overly formal sense unless expressly so defined herein. Well-known functions or constructions may not be described in detail for brevity and/or clarity.
