Abstract: There is provided a method and apparatus for sampling a viscous liquid by aspiration of such liquid from a container in an offtake tube of a probe insertable in the container. A reagent having the characteristic of a solvent is added to the sample to dilute it within the probe after a relatively short distance of travel of the sample within the probe. The reagent is fed into the probe at a first predetermined flow rate and the admixture is aspirated at a second predetermined flow rate which is faster so that the sample is aspirated at a rate determined by the difference between the first and second flow rates.

Abstract: There is provided a spectral flame burner of the preatomizer type having a sample tube the outlet of which is disposed within a carrier gas conduit terminating in a nozzle. The spacing between the outlet of the sample tube and the outlet of the nozzle is adjustable during the normal operation of the analyzer system, including the burner. Improved means is provided to withdraw the outlet of the sample tube to a position in which sufficient gas pressure is developed in the sample tube to blow out any obstruction in the latter, including a lead screw mechanism operatively associated with the sample tube. The burner has an improved cap construction and a control system is provided for the burner to safely shut down the burner when a defect is detected in the burner system.
