Determination of ammonia nitrogen in solid and liquid high-complex matrices using one-step gas-diffusion microextraction and fluorimetric detection

This paper introduces a new method for a one-step determination of ammonia nitrogen (NH3) in high complex solid and liquid samples from the agricultural and livestock sectors. To this end, we developed a simultaneous extraction and fluorimetric labeling of NH3, using gas diffusion microextraction (G...
