摘要： A spectroanalytical system with a plurality of radiation sources and structure defining an analysis region that includes means for thermally energizing a sample material to be analyzed. Analysis beam path defining structure includes means for passing a radiation beam from a radiation source along the analysis beam path through the analysis region for modification by sample material in the analysis region. Analysis structure includes radiation dispersing structure arranged to disperse radiation in the analysis beam path with a spectrum and a radiation sensor. First transducer structure moves the dispersing structure relative to the beam path to apply a selected portion of the radiation dispersed by the dispersing structure to the radiation sensor. Source selector structure is disposed in the analysis beam for selecting radiation from one of the radiation sources along the analysis beam path, second transducer structure is coupled to the source selector structure for directing radiation from a particular radiation source along the analysis beam path, and control structure coordinately operates the two transducer structures to apply a particular dispersed wavelength of radiation from the selected radiation source to the radiation sensor.

摘要： A sample processing system for use with analysis apparatus includes tubular structure that defines a continuous elongated flow chamber. The tubular structure has an inlet port at one end, an outlet port at the other end, and a sample inlet port in communication with the continuous elongated flow chamber between the inlet and outlet ports. A first pump flows diluent at a first rate through the inlet port for flow through the continuous elongated flow chamber, and a second pump flows a liquid mixture from the continuous elongated flow chamber through the outlet port at a rate greater than the first rate. With the sample inlet port submerged in a sample to be analyzed, the sample is aspirated through the sample inlet port into the flowing diluent stream in the continuous elongated flow chamber for dilution and application of the diluted sample mixture to sample analysis apparatus for analysis.
