Abstract: The invention relates to a method of recovering Pt or Ag or Pt and Ag from a sulfate solution on an electrode. In particular, the invention concerns a method for recovering Pt or Ag or Pt and Ag from base metal bearing process solution, particularly from a hydrometallurgical sacrificial metal bearing solution containing Zn and/or Ni. In general, the method of the present invention can be used for recovery of precious metals, which are dissolvable in sulfuric acid, from sulfate media based solutions. In addition to Pt and Ag, especially Pd should be mentioned. Deposited precious metal(s) can be recovered from the electrode or the deposition containing electrode can be used as such.

Abstract: The invention relates to an electrospray ionization (ESI) device for forming a stream of ionized sample molecules. The device comprises a sample introduction zone for receiving a liquid-form sample, a tip for spraying the sample into aerosol or gaseous form, and a flow channel connecting the sample introduction zone and the tip. According to the invention, the flow channel comprises an array of transversely oriented microstructures adapted to passively transport the liquid-form sample introduced to the sample introduction zone to the tip by means of capillary forces. The invention concerns also a manufacturing method and applications of the ESI device, in particular mass spectrometry. The device can be used without external pumping of sample liquid.

Abstract: A method and an apparatus for examining a sample by means of mass spectrometry. According to the method, the solution comprising the sample to be examined is vaporized in a vaporizer, the vaporized sample solution is sprayed, using a gas flow, into a corona discharge zone, where the examined sample is ionised according to the APCI method, using a corona discharge, to generate gas phase ions, and the ions are separated and directed to a detector. According to the present invention, a vaporizer is used, which is fabricated as a micromechanical structure which comprises the flow channels for the solution and for the carrier gas possibly used for feeding the solution, as well as the heater of the vaporizer, and which are all included in a monolithic structure. The solution is especially suitable for cases in which a very sensitive analysing technique is needed, or in which the available sample quantity is very small (less than 1 ?L).

Abstract: A device and a method for multidimensional separation and analysis of molecules is disclosed. The device comprises a chamber for subjecting a first substance to a first analysis step and a space for receiving a second substance. The device is configured to apply pressure to the second substance to move the second substance towards a product of the first analysis step for providing a sample for a second analysis step.
