摘要： An elution apparatus and a detection apparatus are described. The elution apparatus includes: a sample trap for trapping a sample; and one or more pumps and/or valves to move a liquid eluent and a liquid eluate, wherein the eluate includes an extracted portion of the sample that is extracted by the eluent. The detection apparatus includes: a capillary having a low-voltage (LV) end portion to receive a sample; and a conductivity detector coupled to a high-voltage (HV) end portion of the capillary to generate signals based on conductivity of a monitored portion of the capillary in the HV end portion, wherein the conductivity detector is electrically isolated from the LV end portion.
