TOC (Purging Method) TNT, 0,3 - 20,0 mg/L C

Description

TNT (2760345) Total Organic Carbon (TOC) cuvette test from Hach.

Аpplication: For water, drinking water and wastewater.

Method: Direct.

Method description: The total organic carbon (TOC) concentration is determined by first sparging the sample under slightly acidic conditions to remove the inorganic carbon. In the outside vial, organic carbon in the sample is digested by persulfate and acid to form carbon dioxide. During digestion, the carbon dioxide diffuses into a pH indicator reagent in the inner ampule. The absorption of carbon dioxide into the indicator forms carbonic acid. Carbonic acid changes the pH and thus the color of the indicator solution. The amount of color change is related to the original amount of carbon present in the sample. The measurement wavelengths are 598 and 430 nm for spectrophotometers or 610 nm for colorimeters.

Platform: Test 'N Tube.

Special remarks: 16 mm TNT products can be evaluated on DR900 only.
