Following recent validation work on improved methods, we are now applying a change to the standard method we offer for Total Nitrogen analysis in water samples.

At present we measure Total Nitrogen by calculation from Kjeldahl and Oxidised Nitrogen measurements. Effective from Monday 29th June, for all water matrices, we will test for Total Nitrogen by TN Analyser. This will contribute to lower limits of detection, faster analysis of samples and turnaround times for your results.

The test is accredited by UKAS to ISO17025 standard on Potable Water, Surface Water, Groundwater and Industrial and Sewage Effluents.

Total Nitrogen Limits of Detection

If you require Total Kjeldahl Nitrogen or Total Oxidised Nitrogen results on your Certificate of Analysis or have any questions relating to your quotes please email sales@fitzsci.ie or phone 041 98 45440 to discuss.

This update is part of a number of exciting investments and improvements we will be making over the coming weeks. We look forward to our continued relationship as your trusted scientific partner.
