Optical analysis and sampling systems

An optical analysis system comprising:

• an optical cell having an interior fluid chamber defined by an interior surface of a housing;
• a process inlet disposed in the housing and in fluid communication with the interior fluid chamber;
• a process outlet disposed in the housing and in fluid communication with the interior fluid chamber, wherein the process inlet and process outlet facilitate the flow of a fluid through the interior fluid chamber;
• a temperature sensor configured to measure a temperature within the interior fluid chamber and a temperature controller configured to control a temperature of the optical cell;
• an optical element configured to direct electromagnetic radiation through a portion of the fluid flowing through the interior fluid chamber;
• a sampling outlet disposed in the housing and in fluid communication with the interior fluid chamber;
• a first bi-directional pump in fluid communication with the sampling outlet and a first storage vessel, wherein the first bi-directional pump is configured to withdraw a first sample of the fluid flowing through the interior fluid chamber via the sampling outlet and to cause the first sample to flow into the first storage vessel;
• and
• an analyzer configured to process at least a portion of contents of the first storage vessel to provide a standard model, a calibration model, or one or more of spectral, chemical, and mechanical characteristics of the portion, or a combination thereof.
