Theory of Operation	Model 6750

The construction of the patented UV reactor in the Model 6750 affords superior oxidation by precisely controlling the sample temperature, adding a precise amount of ultra-pure persulfate reagent (P/N ST40000) and precisely controlling the carrier gas flow rate.

Pump (P-1) continuously meters a precise amount of carbonate-free sample from the sparger to the UV reactor. Pump (P-3) continuously meters a precise amount of persulfate reagent to the reactor. Mass Flow Controller (MFC-1) precisely controls the carrier flow rate. Refer to Figures 2-6 and 2-7.
