ABSTRACT:
An improved fluorescence monitoring apparatus for measuring fluorescent emission from a sample in response to sample irradiation by an emission beam is disclosed. The apparatus employs a sample tube having surface roughness characteristics which substantially reduce background fluorescence emission due to contamination of the tube holder in the apparatus. Also disclosed is a method of reducing such background, by texturing of a sample tube to produce desired roughness characteristics.
