The present invention relates to an analysis system capable of online transferring an analysis sample and promptly acquiring an analysis result. The analysis system capable of analyzing the analysis samples supplied from at least two sites, with one analysis apparatus, and requiring no cleaning process for a nebulizer and a spray chamber, is provided. The present invention relates to analysis system including at least two sample individually transferring units. Each sample transferring path of the sample individually transferring units is coupled to a plasma torch of a common analysis unit including the one analysis apparatus with inductively-coupled plasma or microwave plasma. Each sample transferring path has a main flow path, a makeup gas supply path, and a drain flow path. The plasma torch has a sample introducing pipe that introduces the atomized analysis sample, provided at a substantially center. The inner diameter of the drain flow path is equivalent to or larger than the inner diameter of an inlet portion of the sample introducing pipe of the plasma torch.

The invention provides a method and apparatus for improving throughput in spectrometry, the method comprising the steps of loading sample-containing liquid into a liquid injection device through a first outlet in the injection device, and ejecting at least some of the sample-containing liquid from the liquid injection device either in the form of droplets or in the form of a jet which subsequently breaks up into droplets due to instability; characterized by the sample ejection being through the first outlet of the liquid injection device in a direction such that the sample-containing fluid enters an inlet of a torch.

An ion source includes a plasma generator for supplying plasma at an ionization region proximate to a sample surface. The plasma generator applies energy that may be utilized for desorbing analytes from the sample surface as well as for generating plasma by which analytes are excited or ionized. Desorption and ionization/excitation may be controlled as individual modes. The ion source may be interfaced with an ion-based or optical-based spectrometer. A sample support may be provided, which may be capable of performing analytical separation.

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 method and system for generating vapors of liquid solutions where a pneumatically modulated liquid delivery system maintains a defined flow rate for a liquid solution. The pneumatically modulated liquid delivery system includes a flow meter configured to measure a flow rate for the liquid solution flowing from a pressure vessel; a microcontroller configured to determine a pressure necessary to achieve the defined flow rate; and an electronic pressure control unit configured to adjust the pressure inside the pressure vessel. The system includes a nebulizer coupled to the pneumatically modulated liquid delivery system configured to receive the liquid solution from the pneumatically modulated liquid delivery system at the defined flow rate and configured to generate an aerosol of the liquid solution. A heat tube can vaporize the aerosol generated by the nebulizer.

Efficient and economic devices and methods for dual-mode sample introduction of liquid samples to an analytical detector exemplified by an inductively coupled plasma mass spectrometer (PVG-ICPMS) or an inductively coupled plasma optical emission spectrometer (ICPOES) are described. Various embodiments of pneumatic nebulization (PN)-photochemical vapor generation (PVG) dual-mode introduction can enhance introduction efficiency for PVG-active elements and smooth, bubble-free nebulization for all elements. A compact yet highly efficient porous membrane gas-liquid separator (MGLS) in its various embodiments plays a key role in systems and methods described.

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.

A sample droplet generator transforms a segmented array of sample material into a continuous stream of droplets containing analytes. The droplets may serve as a sample source for a wide range of detectors and analytical instruments. As one example, the droplets may be introduced into an ion source of a spectrometer that measures ions produced from the droplets or photons emitted from the droplets.
