Reagent Tubing:
After acid digestion, the water sample is mixed with a conditioning agent. Under acidic conditions in the presence of a chromogenic agent (typically 1,5-diphenylcarbazide), hexavalent chromium [Cr(VI)] reacts to form a violet-red chelate complex (λ<sub>max</sub> = 540 nm). The spectrophotometric analyzer quantifies Cr(VI) concentration by measuring absorbance changes proportional to the Beer-Lambert law. The chromogenic complex concentration directly correlates with the original Cr(VI) content in the sample.
