1. A system for measuring component concentration in a sample, the system comprising:
a container for containing the sample;
a first light source positioned to emit light through the sample in the container;
a first light sensor positioned to receive light from the first light source that has passed through the sample in the container;
a second light source positioned to emit light through the sample in the container;
a second light sensor positioned to receive light from the second light source that has passed through the sample in the container; and
a control circuitry in communication with the first light sensor and the second light source light sensor, the control circuitry configured to:
receive a light intensity measurement from the first light sensor;
cause the second light source to emit light based on the received light intensity;
receive a light intensity from the second light sensor;
determine an adsorption level based on a difference in intensity from the light emitted from the first light source and the light received at the second light sensor; and
calculate a component concentration in the sample based on the adsorption level and a total optical length of light passed between the first light source and sensor and the second light source and sensor.
