摘要:
A method of analysis is disclosed comprising providing a sample on an insulating substrate such as a petri dish (4) and contacting e.g. the rear surface of the insulating substrate with a first electrode (9). The method further comprises contacting the sample with a second electrode (2) and applying an AC or RF voltage to the first and second electrodes (9,2) in order to generate an aerosol from the sample.
摘要:
An apparatus for performing ambient ionisation mass and/or ion mobility spectrometry is disclosed. The apparatus comprises a substantially cylindrical, tubular, rod-shaped, coil-shaped, helical or spiral-shaped collision assembly; and a first device arranged and adapted to direct analyte, smoke, fumes, liquid, gas, surgical smoke, aerosol or vapour onto said collision assembly.
摘要:
A method is disclosed comprising obtaining or acquiring image or other data from one or more regions of a target (2) using an imaging sensor (20). The image or other data may then be used to determine one or more regions of interest of the target (2). An ambient ionisation ion source (1) may then be used to generate aerosol, smoke or vapour (5) from one or more regions of the target (2).
摘要:
A mass and/or ion mobility spectrometry method is disclosed comprising providing a biopsy sample; generating first analyte ions from a first position on said biopsy sample at a first time, and generating second analyte ions from a second different position on said biopsy sample at a second different time; and analysing said analyte ions.

摘要:
A method is disclosed comprising obtaining or acquiring chemical or other non-mass spectrometric data from one or more regions of a target using a chemical sensor. The chemical 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 be used to generate aerosol, smoke or vapour from one or more regions of the target.
摘要:
An apparatus is disclosed comprising a first device for generating aerosol, smoke or vapour from one or more regions of a target, an inlet conduit to an ion analyser or mass spectrometer, the inlet conduit having an inlet through which the aerosol, smoke or vapour passes, and a Venturi pump arrangement arranged and adapted to direct the aerosol, smoke or vapour towards the inlet.
摘要:
A method is disclosed comprising providing a biological sample on a swab 900, directing a spray of charged droplets onto a surface of the swab 900 in order to generate a plurality of analyte ions, and analysing the analyte ions.

A method is disclosed comprising obtaining or acquiring chemical or other non-mass spectrometric data from one or more regions of a target 2 using a chemical sensor 20. The chemical or other non-mass spectrometric data may be used to determine one or more regions of interest of the target 2. An ambient ionisation ion source 1 may then be used to generate aerosol, smoke or vapour 5 from one or more regions of the target 2.
