Abstract
This relates to sampling systems, wherein the sampling is based on removal of material from a sample immersed in a fluid by cavitation induced by high-intensity focused ultrasound. The system includes also a feeding unit for transporting at least part of the removed material from the fluid to a detecting unit. The invention relates also to a method for feeding material from the sample to a detecting unit using the sampling system.
Claims18
A system for sampling material to a detecting means, the system comprising
- a housing for
- a sample and
- a fluid for immersing the sample,
- a transducer configured to emit focused ultrasound waves towards a target on interface between the sample and the fluid for removing material from the sample to the fluid and for producing an acoustic stream in the fluid, and
- a feeding means comprising a first end configured to be positioned between the transducer and the interface, and a second end configured to be connected to the detecting means, and fluid transport means between the first end and the second end, the feeding means configured to transport at least part of removed material to the detecting means.
