摘要： A sample handling apparatus/technique/method for a material analyzer, which provides active, variable concentration of a sample, using a measurement marker introduced into the sample, to measurably concentrate an analyte in a liquid (e.g., water) sample. Active, variable concentration allows otherwise lower level analytes to be concentrated in a measurable way. This enables measurements at higher (e.g., concentrated) levels, which can be extrapolated to obtain their lower, original levels based on the concentration level—measured using the introduced marker as a guide. The sample handling apparatus may be used in combination with an optic-enabled x-ray analyzer, the x-ray analyzer including an x-ray engine with an x-ray excitation path and an x-ray detection path, usable during both during the concentration and analyte measurement.
