Spectrometric Analysis

A method of spectrometric analysis comprises obtaining one or more sample spectra for an aerosol, smoke or vapour sample. The one or more sample spectra are subjected to pre-processing and then multivariate and/or library based analysis so as to classify the aerosol, smoke or vapour sample. The results of the analysis are used for various surgical or non-surgical applications.

A method is disclosed comprising obtaining physical or other non-mass spectrometric data from one or more regions of a target using a probe. The physical or other non-mass spectrometric data may be used to determine one or more regions of interest of the target. An ambient ionisation ion source may then used to generate an aerosol, smoke or vapour from one or more regions of the target.

A system includes a mass spectrometer and associated sample interfacing equipment. The sample interfacing equipment includes a platform structured to support a sample thereon, a fluid source, a high voltage source, a dispensing probe electrically coupled to the high voltage source and defining a fluid dispensing passage therethrough, a collection probe defining a collection passage therethrough, a sensing arrangement coupled to the dispensing probe, and control logic responsive to the sensing arrangement to control distance between the dispensing probe and the sample. The dispensing probe facilitates formation of one or more ionized sample analytes when dispensing the fluid through the dispensing passage proximate to the sample on the platform. The collecting probe receives at least some of the one or more ionized sample analytes to pass through the collection passage into the mass spectrometer for analysis.
