Abstract:
1. A system for analyzing a chemical composition of a specimen, comprising: a plurality of pins closed to liquid flow and each having a tip for contacting a sample and retaining sample over the pin tip, the pins being spaced apart such that sample on one pin does not contact sample on any adjacent pin; a sampling device configured to contact a liquid with a specimen on the tip of at least one pin to form a testing solution; wherein said sampling device comprises a capillary tube defining an outer perimeter of a capillary in fluid communication with an external orifice of said sampling device, said external orifice for forming a meniscus with a liquid in said capillary tube; the tube having a first position where the orifice is distanced from the pin tip such that liquid does not contact the pin tip; and a mechanism for moving said at least one pin and said sampling device relative to one another to a second position such that sample on a single pin tip contacts the meniscus and sample on the pin tip is transferred into the liquid to create a testing solution.
