Abstract: A method and system for concentrating an analyte (A). Liquid droplets (D) of an extractant liquid (Le) are adhered to a wall (10w) of a container, e.g. capillary tube. A sample fluid (Fs) comprising the analyte (A) is provided in the container (10) to contact the liquid droplets (D). The analyte (A) has a higher solubility in the liquid droplets (D) than in the sample fluid (Fs). This causes the analyte (A) to be extracted from the sample fluid (Fs) and concentrated in the liquid droplets (D). After extraction, the liquid droplets (D) are collected, e.g. scraped, from the wall (10w) for obtaining the concentrated analyte (A). A concentrated liquid (La) can be formed by collecting the liquid droplets (D) from the wall (10w). The analyte (A) can be measured in the concentrated liquid (La) using any suitable measurement technique.
