摘要:
A multi-well cassette configuration and an instrument capable of accepting the cassette and thereafter pre-concentrating and purifying analytes from biological samples held in the cassette wells, such as human serum, for subsequent analysis by Matrix-Assisted Laser Desorption Ionization Mass Spectrometry (MALDI MS).

摘要:
The present invention relates to the use of the A286 alloy grade for the manufacture of a sheet, optionally surfaced, making it possible to obtain a conducting plate of mono polar or bipolar type for a fuel cell element. The invention also relates to this optional surface treatment process, which comprises a cold-rolling step followed by a continuous annealing step in an oxidizing atmosphere and by an acid pickling step.
摘要:
The invention relates to a fuel cell comprising a membrane (1) and an electrode (3; 3′), which is associated with a metallic current collector (5) via a fibrous gas diffusion layer (7) in which the state of the surface of the metallic collector surface in contact with the diffusion layer (7) is adapted to that of the surface of the diffusion layer, typically deformed in a superficial manner by mechanical action.
