Abstract

Systems and methods are described for indirect detection of a missed sample from an autosampler. A method embodiment includes, but is not limited to, drawing a fluid through operation of an autosampler; directing the fluid via a fluid line to a valve of a fluid handling system, the valve including or being adjacent to a sensor to detect a presence or absence of liquid sample; directing the fluid from the valve into a holding line coupled to the valve; determining whether a threshold amount of liquid sample is present in the fluid in the holding line; and when it is determined that liquid sample is present in the fluid in the holding line in an amount less than the threshold amount, transferring a carrier fluid having a marker component to an analytic detector, the marker component present in the carrier fluid in an amount indicative of a missed sample.
