#nitrogen measurement
- Azotometer — A laboratory apparatus used for the quantitative determination of the volume of nitrogen released from a chemical reaction, or for measuring the concentration of nitrogenous compounds within a complex substance (such as soil or fertilizers); it typically operates on eudiometric or volumetric principles.
- Azotometer — A laboratory apparatus or precision instrument used for the quantitative determination of the volume of nitrogen released during a chemical reaction or organic decomposition process. This structural device, typically made of borosilicate glass and equipped with a graduated scale, is essential in volumetric elemental analyses for measuring the purity of gaseous compounds.
