摘要： A process for ionizing a liquid can comprising flowing the liquid through a capillary wire bonding tip and applying sufficient voltage to electrospray the liquid sample as it exits therefrom. The electrospray ionization process can further involve passing a liquid sample through an axially disposed aperture in a ceramic capillary wire bonding tip in which the terminus of the aperture flares into a bell-shape where the liquid sample exits therefrom. An add-on device can include gel electroelution and separating devices, and a ceramic capillary sample injection tip for carrying out the aforesaid electrospray ionization process. An adjustably mounted cartridge can also be provided with the add-on device for interchangeably receiving the ceramic capillary sample injection tip.

摘要： A gel electroelution device can have a gel spot column having upstream and downstream openings in fluid communication with an inlet and outlet, respectively. The gel spot column receives a gel spot and negative and positive electrodes are fluid communication with the inlet and outlet, respectively. A gel electroelution process can involve flowing a buffer solution through the gel spot in a first direction, and creating an electric field across the gel spot in the same direction. A separator device can have a generally cylindrical collection reservoir in fluid communication with inlet, filtrate, and retentate ports, a filter intermediate the inlet and filtrate ports. The inlet and retentate ports can intersect the collection reservoir in a manner to induce a cyclonic flow. A flow separation process can involve inducing a generally cyclonic flow in the collection reservoir, and filtering the fluid therein to retain the retentate.

摘要： An instrument and system for the preparation of a sample for analysis provides a crucible holder which improves the holding and control of a melting crucible during operation of the device for agitating a powdered sample and flux while being heated. The crucible holder is coupled to an agitation assembly which provides independently controlled operation on two different axes using separately adjustable variable frequency and amplitude motion along each of the two operating axes to provide an finite number of agitation patterns for the crucible. In one preferred embodiment of the invention, the heating flame is controlled by controlling the supply of compressed air and a combustion gas. In another preferred embodiment of the invention, a pilot burner is provided which both ignites the main burner located under the crucible and preheats the casting dish to a temperature which is substantially the same as the crucible. The pilot also can control air only flow directed to the casting dish for controllably cooling the sample melt to form the sample bead.
