摘要： The present invention relates to the generation of an Atomic Therapeutic Indicator (ATI) for a test sample by the quantification of manganese; in voxels of a 3D region of the sample, wherein the 3D region is topographically defined by co-ordinates X′xY′xZ. The ATI is used to assess the radio-responsiveness i.e. sensitivity or resistance to radiation treatment, of a cancer i.e. a tumour/neoplasm. In a preferred embodiment, the present invention relates to a method of generating the ATI, assessing the radio-responsiveness of a tumour/neoplasm based on the ATI and, based on the assessment, either treating or not treating the tumour with radiation.The present invention also relates to a method of determining if a cancer is likely to reoccur post radiation treatment comprising quantifying the level of manganese in voxels of a 3D region of a test sample from the cancer and determining the frequency of high metallomic regions (HMRs) in the cancer, wherein a high frequency of HMRs is indicative that the cancer is likely to reoccur and a low frequency of HMRs is indicative that the cancer is unlikely to reoccur; and associated methods of treatment.The invention further relates to a method of determining the radio-responsiveness of a melanoma, the method comprising determining the level of melanin in a test sample from the melanoma, wherein the lower the level of melanin the more sensitive the melanoma is to radiation and the higher the level of melanin the more resistant the melanoma is to radiation; and associated methods of treatment.

摘要： A sample support plate (100) for a variety of possible applications, including MALDI mass spectrometry, is disclosed. A plurality of spatially separated sample recipient sites (101) are arranged on the surface of a substrate. The recipient sites are mutually separated by areas having a different wettability than the recipient sites. They are arranged in a plurality of rows consisting of a plurality of recipient sites whose centers are regularly spaced along a first direction with a predetermined periodicity (D1), the rows being regularly spaced along a second direction perpendicular to the first direction with a predetermined centerline distance (D2). Each recipient site has a maximum lateral dimension that is preferably smaller than the diameter of a beam spot (104) of a desorption laser beam (103). In order to enable unsupervised splitting of bulk liquid samples into droplets at the sample recipient sites, the periodicity along the first direction and the centerline distance along the second direction are chosen such that each recipient sites has a next neighbor at a distance that is less than or equal to three times the minimum lateral dimension of each recipient site. In preferred embodiments, the sample recipient sites are arranged in a checkerboard-type pattern or in rows that are inclined relative to the edges of the sample support plate.

摘要： An aerosol particle analyzer includes a laser ablation chamber, a gas-filled conduit, and a mass spectrometer. The laser ablation chamber can be operated at a low pressure, which can be from 0.1 mTorr to 30 mTorr. The ablated ions are transferred into a gas-filled conduit. The gas-filled conduit reduces the electrical charge and the speed of ablated ions as they collide and mix with buffer gases in the gas-filled conduit. Preferably, the gas filled-conduit includes an electromagnetic multipole structure that collimates the nascent ions into a beam, which is guided into the mass spectrometer. Because the gas-filled conduit allows storage of vast quantities of the ions from the ablated particles, the ions from a single ablated particle can be analyzed multiple times and by a variety of techniques to supply statistically meaningful analysis of composition and isotope ratios.

摘要： The current invention involves a method and a device for generating and analyzing ions in order to analyze samples directly without sample preparation. The gaseous neutral molecules are desorbed under atmospheric pressure by a desorption method. The desorbed neutral molecules are then transferred into a low pressure region where they are post-ionized by a mist from an electrospray probe tip or by photons from a vacuum UV source. The generated ions are then focused in a time varying electric field in the low pressure chamber before they are transferred into a mass spectrometer or ion mobility spectrometer for further analysis.
