Claim:
1. A method for diluting a fluid sample comprising: drawing an aliquot of the fluid sample from a first fluid line past a mixing junction and into a second fluid line using a first syringe pump; supplying the aliquot back to the mixing junction through the second fluid line using the first syringe pump; supplying a second fluid, via a second syringe pump, through a third fluid line to the mixing junction to mix the aliquot and the second fluid at the mixing junction and generate a diluted sample, the mixing junction coupled to each of an end of the first fluid line, an end of the second fluid line, and an end of the third fluid line, the end of the third fluid line and the end of the second fluid line having a cross-flow orientation with respect to each other; and supplying the diluted sample from the mixing junction.
