The invention relates to a method for the spectrometry, in particular mass spectrometry, ion-mobility spectrometry, or optical emission spectroscopy, of a sample, comprising the following steps: providing a solid-state generator for generating a high-frequency signal, having a control element for varying the power and/or frequency of the signal, providing a plasma ignition head fed by the signal for generating a plasma jet, applying the plasma jet to a sample, performing a first measuring operation, wherein the plasma jet is generated with a first power of the solid-state generator and a spectrum emitted by the sample, preferably charged ions and/or optical spectrum, is recorded by means of a spectrometer, wherein the first power leads to a soft ionization of the sample, and performing a second measuring operation on the same sample, wherein the plasma jet is generated with a second power of the solid-state generator and a spectrum emitted by the sample, preferably charged atoms and/or optical spectrum, is recorded by means of the spectrometer, wherein the second power leads to a hard ionization of the sample.

A flame atomic absorption spectrophotometer in which an angle of a burner can be manually adjusted and a rotation position of the burner can be easily obtained is provided. An atomization unit burns mixed gas of fuel gas and supporting gas with a burner to form flame, and atomizes a sample by spraying the sample into the flame. Alight source emits a measuring beam into the flame. A detector detects the measuring beam that has passed through the flame. A manual rotation mechanism allows the burner to be manually rotated to change an angle of the burner with respect to an optical path of the measuring beam. A rotation position detection unit detects a rotation position of the burner.

A torch for use in analytic instruments includes a tube subassembly with substantially cylindrical nested inner and outer tubes with coincident central axes, the inner tube having a terminus. The torch also includes a removable injector extending at least partially in the inner tube and having an alignment feature, an inlet, an outlet, and a central axis that is coincident with the central axes of the inner and outer tubes, a seal having a channel for accommodating a portion of the injector, and a base for supporting the tube subassembly, injector, and seal. The seal has a complementary feature to engage the alignment feature of the injector to prevent axial misalignment of the injector and maintain a fixed gap between the terminus of the inner tube and the outlet of the injector.

A nebulizer having a gas capillary and a liquid capillary that are aligned in the same direction within a nebulizer housing is disclosed. The nebulizer includes a nebulizer tip that is substantially parallel to a cross-section of the liquid capillary and to a cross-section of the gas capillary. The tip includes a liquid opening and a gas orifice. The gas capillary may have a non-tapered body and a tapered end. The tip has a roughened surface that allows wetting of the tip with liquid that exits from the liquid opening to form a thin film. The nebulizer may be formed from glass, quartz, one or more polymers, metals, or alloys, or a combination thereof. The nebulizer is capable of handling high solid content samples, and it also offers precision and sensitivity comparable to concentric nebulizers. Methods of introducing a sample into an instrument using the disclosed nebulizer are also disclosed.

A sample introduction system is described that provides temperature-controlled handling and transfer of a sample from an autosampler, through a transfer line, to a heated environment proximate an analytical device. A system embodiment includes, but is not limited to, an autosampler including a temperature-controlled deck to support one or more sample containers; a heating unit including one or more heating elements to one or more fluids to be introduced to a sample removed from the one or more sample containers; a transfer line fluidically coupled with the autosampler and including a heating element configured to transfer heat to fluid flowing through the transfer line; and a sample handling system fluidically coupled with the transfer line and configured to fluidically couple with an analysis device, the sample handling system including a housing and a heating element configured to control a temperature of an environment defined by the housing.

A laser ablation device is provided with: a laser light source that outputs a femtosecond pulse laser beam; an optical system that includes a first mirror rotatable about a first axis, a second mirror rotatable about a second axis, a first driving source for rotating the first mirror about the first axis, and a second driving source for rotating the second mirror about the second axis, and that reflects the laser beam from the laser light source toward a sample by the first mirror and the second mirror; and an irradiation controller that, on the basis of the two-dimensional coordinate position of an analysis position, controls the first driving source and the second driving source to irradiate the analysis position with the laser beam.

Apparatus, systems, and methods for identifying and quantifying chemical components in a high-melting-point liquid. One such method includes: receiving, into a nebulizer assembly, a high-melting-point liquid from a molten liquid conduit; aerosolizing, using the nebulizer assembly, at least a portion of the received high-melting-point liquid; delivering, into one or more instruments, the aerosolized high-melting-point liquid from the nebulizer; and chemically analyzing, using the one or more instruments, the aerosolized high-melting-point liquid.

A method of forming an electronic part comprising a metal component is provided. The method includes obtaining an unverified mineral sample from a mine site, analyzing the unverified mineral sample via quantitative mineralogical analysis and comparing data collected during the quantitative mineralogical analysis for the sample to data in a database that corresponds to quantitative mineralogical analysis collected for verified mineral samples sourced from one or more mine sites from the conflict-free geographic region to determine if the unverified mineral sample is sourced from one or more mine sites from the conflict-free geographic region. If it is determined that the unverified mineral sample is sourced from one or more mine sites from the conflict-free geographic region, the method then involves converting the unverified sample into the metal component. The electronic part can be a capacitor, medical device, filter, inductor, active electrode, antenna, sensor, or battery.

To provide: an atomizer that allows a sample liquid to be made into minute droplets stably and that inhibits clogging of an aerosol gas outlet by salting out or the like when atomizing a sample containing a high density matrix; a sample introduction unit that includes the atomizer; and an analysis device. An atomizer includes: a liquid supply tube that has a first channel in which a liquid can circulate and that has, on one end, an outlet to spray the liquid; and a gas supply tube that encloses the liquid supply tube with a gap therebetween, that has a second channel in which a gas can circulate, and that has, on one end, an outlet to spray the gas. The second channel is defined by the outer circumferential face of the liquid supply tube and the inner circumferential face of the gas supply tube and has a narrow portion upstream of the outlet.

A system can include an exchangeable mounting structure having a visual marking or coloring and at least one physically associated sample introduction system component having an indicating mark or color matching the visual marking or coloring of the exchangeable mounting structure. The visual marking or colored corresponds to a sample analysis configuration for analyzing a particular sample type at an analytical instrument.
