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, everytime.
Simplified TKN (s-TKN™) is method accepted for compliance reporting in many states. Please check with local regulators for acceptance in your state.
Hach Method 10242 is compliant for EPA wastewater reporting and gives three results for each test – Total Nitrogen, combined nitrate and nitrite, as well as TKN. Unique vial reagent system digests the sample at 120 °C, increasing safety while eliminating ammonia contamination and the need to clean glassware. TNT880 has a range up to 16 mg/L TKN.
Benefits
Easy and safe handling
The innovative vial and reagent delivery makes tests easier to use than powder pillows or liquid reagents and significantly reduces spillage or contamination risk.
No reagent blank necessary
The high quality of TNTplus® vials, tight reagent production controls, instrument calibration verification, and high instrument stability all combine to eliminate the need to run reagent blanks—saving you time and money!
Lot after lot – Be Right
Truecal™ with each vial includes the calibration data for each individual lot, reducing variation in results. This allows you to meet reporting standards and to perform proficiency testing with higher confidence.
Automatic method detection
The bar-coded vials allow for automatic method detection and measurement by the spectrophotometer, considerably increasing the speed of analysis. Errors are reduced as instrument averages 10 readings and rejects outliers from scratched, flawed, or dirty glassware.
Documented shelf life and COA
New 2D barcode details batch number and expiry date of reagents, which are documented along with the measurement result. An automatic warning is issued if expiry date has passed. Lot specific information (COA) is available on RFID tag on the box.
