Abstract
Method and apparatus of spectroscopy or the like on extremely small samples in which a drop is held between two opposing surfaces by surface tension and one surface is controllably toward and away from the other. To provide and transmit exciting energy through the drop for measurement, optical fibers go through a surface and finish flush with the surface. One of the surfaces can be swung clear of the other for easy cleaning between tests. Means for determining wetted surface are provided.
