Photonic measurement instrument using fiber optics

A photonic measurement system including

• a source module including one or more light sources;
• a sample module including at least two analysis chambers, wherein one or more of the analysis chambers contains a sample to be analyzed;
• a detection module including a detector that produces signals associated with each of the analysis chambers;
• a first set of fiber optic cables that guide light from the one or more light sources to each of the analysis chambers;
• a second set of fiber optic cables that guide light from each of the analysis chambers to the detector;
• a processing sub-system that processes the signals produced by the detector;
• and
• a system controller that controls the one or more light sources and the analysis chambers to operate a selected analysis chamber to perform a sample analysis and controls the processing sub-system to process the signals associated with the selected analysis chamber as measurement signals.

An atomic absorption spectrometer including

• one or more light sources, wherein the light sources are of first and second types;
• at least two analysis chambers, wherein at least one of the analysis chambers is a furnace atomizer and at least one of the analysis chambers is a flame atomizer;
• a first set of fiber optic cables that guide light produced by the one or more light sources to each of the analysis chambers, wherein the first set of optic cables includes a selector/mapper that maps optical fibers to guide light from each of the first and second types of light sources to respective analysis chambers;
• a second set of fiber optic cables that guide light from the respective analysis chambers to a detector;
• the detector configured to produce signals corresponding to intensities of light guided to the detector from respective cables of the second set of fiber optic cables;
• a processing sub-system that processes signals provided by the detector, wherein the signals associated with a non-selected analysis chamber are processed as reference signals;
• and
• a system controller that controls the one or more light sources and the analysis chambers to operate a selected analysis chamber to perform a sample analysis and controls the processing sub-system to process the signals associated with the selected analysis chamber as measurement signals.
