Flow chamber for online fluorometer

A flow chamber comprising:

• a housing that defines a cavity configured to receive a sensor head and to position the sensor head in a flow of fluid for analysis, the sensor head including at least one light source configured to emit light into the flow of fluid, at least one detector configured to detect fluorescence emissions from the flow of fluid, and a temperature sensor configured to sense a temperature of the flow of fluid;
• an inlet port extending through the housing and configured to communicate the flow of fluid from outside of the cavity to an interior of the cavity;
• and
• an outlet port extending through the housing and configured to communicate the flow of fluid from the interior of the cavity to back outside of the cavity,
• wherein the housing is configured such that, when the sensor head is inserted into the housing and the flow of fluid enters the housing via the inlet port, the flow of fluid divides into at least a major stream passing through a first physical channel adjacent the light source and the detector and a minor stream passing through a second physical channel adjacent the temperature sensor, the first physical channel being different than the second physical channel.

A fluorescence analysis system comprising:

• means for detecting fluorescent emissions from a flow of fluid;
• means for sensing a temperature of the flow of fluid;
• and
• means for receiving and housing the means for detecting fluorescent emissions and the means for sensing the temperature,
• wherein the means for receiving and housing defines a plurality of fluid channels that include at least a major physical fluid channel configured to direct fluid adjacent the means for detecting fluorescent emissions and a minor physical fluid channel configured to direct fluid adjacent the means for sensing the temperature, the major physical fluid channel being different than the minor physical fluid channel.
