Claim 0:
1. A system for obtaining saturate, aromatic, resin, and asphaltene (SARA) fractions of a hydrocarbon sample, comprising:
a microfluidic portion constructed to receive a hydrocarbon sample, separate and analyze asphaltenes from the hydrocarbon sample, and discharge a permeate containing maltenes; and
a chromatographic portion coupled to the microfluidic portion and constructed to receive the permeate therefrom and separate and analyze saturate, aromatic, and resin fractions in the permeate,
wherein the chromatographic portion includes a refractometer,
wherein the chromatographic portion further includes a selection valve coupled to at least one saturate reservoir, at least one aromatic reservoir, and at least one resin reservoir,
wherein the selection valve is configured to allow the separated saturate, aromatic, and resin fractions to flow to the at least one saturate reservoir, the at least one aromatic reservoir, and the at least one resin reservoir, respectively, and
wherein the refractometer is fluidly coupled between the selection valve and the at least one saturate reservoir.
