Apparatus for determining amino acids

摘要

Apparatus for measuring fluorescence comprises a metal block having a first recess for a sample mount and a second recess for a beam divider. A receiving bore connects both recesses and extends axially from the metal block. A radiation source and an optical focusing device are provided to introduce radiation into the receiving bore. Two exit bores extend from the recesses at an angle, and reflected or fluorescent radiation emitted by the sample and the beam divider pass through the exit bores. Detectors are at the exit bores to measure the radiation.
