摘要： A demountable plasma torch assembly suitable for use in ICP spectrometry comprises a first tube having an inner diameter and a second tube disposed concentrically within the first tube, wherein the second tube has an outer diameter that is less than the inner diameter of the first tube. The first and second tubes are supported by a torch body. The torch body includes a first bore configured to receive an end of the first tube, a second bore configured to receive an end of the second tube, and a manifold disposed between the first bore and the second bore to receive a gas for injection between the first tube and the second tube. The manifold has an outer diameter at least substantially equal to the inner diameter of the first tube and an inner diameter at least substantially equal to the outer diameter of the second tube.

摘要： A torch assembly includes a first tube having opposing first and second ends and a first body structure between the opposing first and second ends. The torch assembly also includes a second tube having opposing first and second ends and a second body structure between the opposing first and second ends. The torch assembly further includes a support jacket. The support jacket includes a support structure. The support structure defines an aperture extending along an axis oriented along a generally longitudinal direction of the support structure. The first tube and the second tube are in a substantially concentric configuration when the second end of the first tube and the second end of the second tube are inserted into the aperture of the support structure.

摘要： An enclosure for an automated sampling and/or dispensing device for minimizing contamination to samples enclosed therein. Further, the enclosure may minimize user exposure to the enclosed samples allowing for the containment of potentially hazardous chemicals. In an embodiment, the enclosure includes at least one flexible panel which allows a user to efficiently access the device by retracting the at least one flexible panel. In addition, the at least one flexible panel allows the enclosure to be shipped efficiently for the enclosure may be disassembled into smaller pieces and thus, be shipped in a smaller box when compared to enclosures with non-flexible panels/doors. Moreover, the use of the at least one flexible panel allows the enclosure to be shaped to accommodate varying shaped automated sampling and or dispensing devices and assemblies.

摘要： Systems and methods for controlled, inline introduction of chemical agents to an inline fluid sample are described. A method embodiment includes, but is not limited to, receiving a fluid sample with a valve; receiving a chemical agent with the valve; introducing the fluid sample and the chemical agent inline via a mixing port of the valve to produce a mixed sample; transferring the mixed sample to a second valve; directing the mixed sample to a sample holding loop fluidically coupled with the second valve; holding the mixed sample within the sample holding loop for a holding period of time to permit a reaction between the fluid sample and the chemical agent; and directing the mixed sample from the sample holding loop to an analytic instrument following expiration of the holding period of time.

摘要： Systems and methods for providing multiple lumens within a single sample probe of an autosampler system are described. In an aspect, a sample probe for an autosampler system includes, but is not limited to, a tube enclosing at least a portion of a plurality of lumens; and a controller communicatively coupled with a fluid handling system to introduce or draw one or more fluids through each of the plurality of lumens, wherein during a droplet purge operation, the controller is configured to expel a gas from a tip of one of the lumens to purge a droplet of fluid from the tip.
