ACOUSTIC SAMPLE INTRODUCTION FOR ANALYSIS AND/OR PROCESSING |
摘要 |
The invention relates to the efficient transport of a small volume of fluid, such as may be required by mass spectrometers and other devices configured to process and/or analyze small samples of biomolecular fluids. Such transport involves nozzleless acoustic ejection. In some instances, sample molecules contained in droplets of fluid are introduced from a reservoir into an ionization chamber of a analytical device. In other instances, sample molecules are introduced into a small capillary by directing focused acoustic radiation at a focal point near the surface of a fluid sample. In still other instances, acoustic ejection is used to form an array on a surface, wherein the features of the array are ionized for analysis. The invention may be used with microfluidic devices. Thus, the invention facilitates the processing and/or analysis of various types of samples, such as biomolecules having high molecular weights. |
