Abstract
A cooled liquid sample dispensing system comprises a pair of pins for holding a droplet of liquid therebetween and a cooling element. Each pin includes a tip spaced predetermined distance from the other pin to define a sample acquisition region. The pins acquire and hold a droplet of the liquid sample in the sample acquisition region formed in the space between the tips and apply the droplet to a selected sample handing system. The cooling element, when activated, cools the droplet of liquid to reduce evaporation.
