Multiple functions ion mobility spectrometer device
Embodiments of the present disclosure provide an ion mobility spectrometer device. The ion mobility spectrometer device includes: an ion mobility tube, a sampling device, and a sampling and circulating gas path. The sampling device includes a solid sample desorption device and a gas sampling device. The solid sample desorption device is configured to process the solid sample into a first mixed gas containing the solid sample, and the gas sampling device is configured to process the gas sample into a second mixed gas containing the gas sample. The sampling and circulating gas path is configured to transfer the first mixed gas and/or the second mixed gas into the ion mobility tube for detection.
DEVICE FOR EXTRACTING A MOLECULE OF INTEREST FROM A SAMPLE MATRIX, AND ASSOCIATED METHODS
A device for extracting a molecule of interest from a sample matrix. The device includes a support comprising a support surface; a sealing layer that at least partially coats the support surface; and an extractive phase coating applied to a portion of the sealing layer. The extractive phase coating is adapted to contain the molecule of interest. The sealing layer sufficiently coats the support surface to prevent the support surface from coming in contact with the sample matrix when the extractive phase coating is fully immersed in the sample matrix. Analytical screening devices and methods of manufacture are also disclosed.
ANALYSIS OF FOOD SAMPLES
A method of analysing a food sample (3) comprises generating analyte ions from a food sample using ambient ionisation (5), analysing (1) the analyte ions to produce a data set, and assessing the data set to identify or determine one or more properties of the food sample.
Rapid online analyzer for 14C-AMS
A rapid online analyzer for a .sup.14C-AMS, comprising: a solid sample processing module, an atmospheric sample collection and processing module, a microflow control module, an AMS module and an automatic control module. Sample preparation and AMS measurement are combined, a solid sample is directly converted into CO.sub.2 gas by an element analyzer and then enters an AMS for measurement, and an atmospheric sample is collected in real time for analysis by the AMS, such that quick and efficient analysis of the solid sample and the atmospheric sample is realized.
Imaging guided ambient ionisation mass spectrometry
A method is disclosed comprising obtaining or acquiring image or other data from one or more regions of a target using an imaging sensor. The image or other data may then 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.
Systems and methods for sample analysis using swabs
The invention generally relates to systems and methods for sample analysis using swabs. In certain aspects, the invention provides systems that include a probe having a conductive proximal portion coupled to a porous material at a distal portion of the probe that is configured to retain a portion of a sample that has contacted the porous material, and a mass spectrometer having an inlet. The system is configured such that the porous material at a distal portion of the probe is aligned over the inlet of the mass spectrometer.
Analysis method for determining halogens in geological samples by ICP-MS
The present invention provides an analysis method for determining halogens in geological samples by ICP-MS. The method includes following steps: weighing a geological sample and ammonium bifluoride in a sample dissolving tank, tightening the sample dissolving tank, and shaking; then heating the sample dissolving tank in a drying oven, and setting a temperature of the drying oven as 200-220° C. and heating time as 1-2 hours; cooling the sample dissolving tank to room temperature so as to obtain a solid mixture after heating is ended, adding ammonium hydroxide into the solid mixture, centrifuging, removing a precipitate, and collecting the supernatant; adding an internal standard solution into the supernatant, and uniformly mixing; and optimizing the ICP-MS to an optimal state, testing content of chlorine in the supernatant under a condition of medium resolution m/Δm=4000, and testing content of bromine and iodine in the supernatant under a condition of low resolution m/Δm=300.
