Abstract
Methods for processing samples are presented, said methods useful for, among other uses, collection and transport of liquid or other samples for analysis by mass spectrometry or other means, wherein a filament is used for collection or transport of samples. Methods for precisely positioning a filament and sensing material in contact with or adhering to a filament are presented. Said methods are in at least some aspects further useful for identification of microorganisms, bulk extraction of lipids, detecting infections and other diseases, and other purposes.
Claims17
A method, comprising:
- using an apparatus to transfer material from a source location to a target location;
- and
- performing a spectroscopic analysis on the material at the target location;
- wherein the apparatus comprises a head portion configured to movably receive a filament having a first end for carrying the material, a transporting device configured to transport the head portion relative to the source location and relative to the target location, a driving device configured to advance the filament towards the head portion and to retract the filament away from the head portion, and a trimming device configured to trim the first end of the filament;
- wherein using the apparatus includes moving the first end of the filament into contact with the material at the source location, moving the first end of the filament and a portion of the material coupled to the first end of the filament from the source location to the target location, and moving the portion of the material coupled to the first end of the filament into contact with the target location to deposit the portion of the material at the target location;
- wherein using the apparatus includes, after the portion of the material is deposited at the target location, trimming the first end of the filament.
3 more elements
A method, comprising:
- transferring material from a source location to a target location by positioning a first end of a filament at the source location to collect material on the first end of the filament and then positioning the first end of the filament at the target location to deposit some or all of the material at the target location;
- and
- performing a spectroscopic analysis on the material at the target location.
