Abstract: Sample preparation systems and methods for inline autodilution of fluid samples are described. A system embodiment includes, but is not limited to, a filter probe including a probe tube, a probe fluid line, and a filter having an array of through-holes to block particulates present in a fluid sample to provide a filtered sample; a probe valve; a nebulizer valve; a plurality of fluid lines including (i) a sample line and (ii) a dilution line; a pump system; and a controller configured to access sample information associated with the fluid sample to determine a dilution factor for the fluid sample, the controller configured to change the configuration of the probe valve or the nebulizer valve based on the dilution factor to direct, via action of the pump system, the filtered sample into the dilution line prior to the sample line for fluid samples having a dilution factor greater than one.
