摘要： The invention relates to an apparatus for forming liquid droplets, such as a micro nebulizer, useful for preparing samples for subsequent analysis via MS, AA, ICP, CE/MS, and similar analytical systems. The apparatus has a mechanically stabilized inner microtube or needle, thereby ensuring controllably uniform droplet size. The mechanical stabilization is provided by securing the inner microtube or needle, such as by narrowing the inner diameter of the outer microtube or otherwise narrowing the annular intermediate space between the inner and outer microtubes for a predetermined length. Thus, the inner microtube is secured in a centered or otherwise predetermined fixed radial position, with minimum perturbation of the fluid flow. Further, a tip, when coupled with the exit end of the outer microtube, provides a region in which the sheath fluid flow in the outer microtube stabilizes prior to both exiting the tip and colliding with the liquid analyte exiting the inner microtube.
摘要翻译： 本发明涉及用于形成液滴的装置，例如微型喷雾器，可用于制备样品用于随后通过MS，AA，ICP，CE / MS和类似分析系统的分析。 该装置具有机械稳定的内微管或针，从而确保可控制地均匀的液滴尺寸。 通过固定内部微管或针来提供机械稳定性，例如通过使外部微管的内径变窄或以其它方式使内部和外部微管之间的环形中间空间变窄预定长度。 因此，内部微管被固定在中心或另外预定的固定的径向位置，同时具有最小的流体流扰动。 此外，当与外部微管的出口端耦合时，尖端提供了一个区域，其中外部微管中的鞘液流动在两个离开尖端之前稳定，并且与离开内微管的液体分析物碰撞。

摘要： A multipole ion guide comprises rods disposed about an axis, each of the rods having a first end and a second end remote from the first end. Each of the rods is disposed at a respective greater distance from the axis at the first end than at the second end. The multipole ion guide comprises means for applying a radio frequency (RF) voltage between adjacent pairs of rods, wherein the RF voltage creates a multipole field in a region between the rods; and means for applying a direct current (DC) voltage drop along a length of each of the rods. A mass spectroscopy system is also disclosed.

摘要： An atmospheric pressure ion source, e.g. for a mass spectrometer, that produces ions by atmospheric pressure photoionization (APPI). It includes a vaporizer, a photon source for photoionizing vapor molecules upon exit from the vaporizer, a passageway for transporting ions to, for example, a mass spectrometer system, and a means for directing the ions into the passageway. The center axis of the vaporizer and the center axis of the passageway form an angle that may be about 90 degrees. Included in the invention is a method for creating ions by atmospheric pressure photoionization along an axis and directing them into a passageway oriented at an angle to that axis.
