Abstract: An improved apparatus and method for making optical measurements of a sample is described. In one embodiment, the apparatus is a microvolume sampling mechanism comprised of two opposing optical measurement surfaces. A sample is held by surface tension between the two opposing optical measurement surfaces. Light is transmitted through the sample and received by optical fibers, which measure the absorbance of the sample. This absorbance can be used to determine the concentration of the sample.
