Total Nitrogen Reagent Set, LR, TNT - Hach
Capped 16-mm vials provide a self-contained package for mixing and measurement. All necessary reagents and vials are contained in the package. Perform digestions and photometric measurements in the same vial. Save time, space and effort.
Digestion is required for total nitrogen determinations. The vials must be mixed carefully for accurate results. Start each vial inversion with the vial in the vertical position, with the cap on the top. Turn the vial upside-down and wait for all of the solution to flow down to the cap.
Hach Lange™ Total Nitrogen Reagent Set, LR, TNT - Fisher Sci
For determination of Total Nitrogen by the Persulfate Digestion Test 'N TubeTM method: Hach Method 10071. Brand: Hach Lange™ 2672245
Simplified TKN (s-TKN) TNTplus Vial Test (0-16 mg/L N), 25 Tests - Hach
Expert Total Kjeldahl Nitrogen test made simple. Total Kjeldahl Nitrogen TNTplus ® chemistry and your Hach spectrophotometer are engineered to simplify water analysis for accurate results.
Scope and application: For water and wastewater. Table 1 shows all of the instruments that have the program for this test. The table also shows the adapter and light shield requirements for the applicable instruments that can use TNTplus vials.
The determination of the total nitrogen, nitrate and nitrite concentration is based on three methods, combined in one analyzer. The total nitrogen concentration is determined in the ‘TN’ method. The nitrate concentration is determined in the ‘NO3-N’ method. The nitrite concentration is determined in the ‘NO2’ method.
Scope and Application: For water and wastewater. Digestion is required for determining total nitrogen. The digestion procedure is included in the method. COD Reactor. Heat to 103-106 °C (optimal temperature is 105 °C). Place the plastic shield in front of the reactor.
The determination of total nitrogen and total phosphorus is based on two methods, combined in one analyser. The total nitrogen concentration is determined in the ‘TN’ method.

LCK238 LATON - Hach
Inorganically and organically bonded nitrogen is oxidized to nitrate by digestion with peroxo-disulphate. The nitrate ions react with 2.6-dimethylphenol in a solution of sulphuric
Organically bound nitrogen is digested by hot fuming sulphuric acid in the presence of catalysts and converted to ammonium, which, after steam distillation, can be determined as so-called ”Total Kjeldahl Nitrogen“ (TKN) together with the ammonium-nitrogen which was originally present; the cuvette test LCK 303 ammonium is used for this purpose.
