Abstract:
A total nitrogen measurement apparatus comprising an ultraviolet lamp comprising: a light emission section and a holding section for holding the light emission section, the holding section being formed of a material not including iron; a reaction vessel having a space where the light emission section is to be inserted and a sample water is to be contained around the light emission section for converting nitrogen compounds in the sample water contained in the reaction vessel into nitrate ions by oxidative decomposition using ultraviolet rays from the light emission section; and a measurement section configured to perform absorbance measurement on the sample water including the nitrate ions.
