Abstract
A sampling method, fluid collection system, and auxiliary sampling device to assist an autosampler in collecting samples from a fluid source. The sampling device includes a support frame and a motorized actuator, with a piston, attached to an end of the support frame. A sample arm has an upper end disposed at an end of the support frame opposite the motorized actuator and a lower end with an inlet to receive a fluid sample. A cable and pulley mechanism links the sample arm to the piston. A fluid conduit within the sample arm has a fluid intake end connected to the inlet and a fluid discharge end connected to an autosampler. The cable and pulley mechanism pivots the sample arm when the motorized actuator pushes or retracts the piston to position the inlet at desired positions within the fluid source so that the autosampler collects multiple samples at various depths.
