ABSTRACT:
Techniques for measuring light absorption of liquid samples are described herein. According to one embodiment, an apparatus includes an upper arm having a first measuring surface and a lower arm having a second measuring surface coupled to the lower arm via a hinge. The upper arm is capable of swinging via the hinge. One of the measuring surfaces is coupled to a light source while the other is coupled to a detector. The apparatus further includes an actuator configured to position the upper arm into a first measuring position. The first measuring surface of the upper arm and the second measuring surface of the lower arm are spaced approximately to contact and sandwich a liquid sample in between to form an optical path, such that light generated from the light source is received and detected through the light path by the detector for measuring light absorption by the liquid sample. Other methods and apparatuses are also described.
