Product Number: TNT880
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.
Hach Method 10242 Revision 2 (Simplified Spectrometric Measurement of Total Kjeldahl Nitrogen in Water and Water) is a USEPA Equivalent Method under 40 CFR 136.6 (Method Modifications and Analytical Requirements) that is compliant for the purposes of NPDES regulatory monitoring and reporting under the Clean Water Act. Please check with your local regulator for use under NPDES discharge permit.
The innovative vial and reagent delivery makes tests easier to use than powder pillows or liquid reagents and significantly reduces spillage or contamination risk.
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!
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.
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.
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.
