摘要
The invention relates to the efficient transport of a small fluid sample such as that may be required by analytical devices such as mass spectrometers configured to analyze small samples of biomolecular fluids. Such transport involves nozzleless acoustic ejection, wherein analyte molecules are introduced from a reservoir holding a fluid into an ionization chamber of an analytical device or a small capillary by directing focused acoustic radiation at a focal point near the surface of the fluid sample. This facilitates the analysis of various types of analytes such as biomolecular analytes having a high molecular weight.
