Phosphorus in wine may be determined directly or indirectly by atomic absorption spectrometry. The direct method uses the carbon rod atomizer as the excitation source and a phosphorus hollow cathode lamp. In the indirect determination, one measures the amount of molybdenum that will complex with phosphorus in the wine. Both nitrous oxide-acetylene and air-acetylene flames are suitable as atomization sources in this indirect method. The resultant data have been compared with those from the AOAC colorimetric method (11.032-11.034). A 2-sample comparison test showed the results to be insignificantly different at the 95% confidence limits.
葡萄酒中的磷可以通过原子吸收光谱法直接或间接测定。直接法使用碳棒原子化器作为激发源和磷空心阴极灯。在间接测定中，人们测量与葡萄酒中的磷络合的钼的量。氧化亚氮-乙炔火焰和空气-乙炔火焰都适合作为这种间接法中的原子化源。所得数据已与美国官方分析化学师协会（AOAC）比色法（11.032 - 11.034）的数据进行了比较。双样本比较试验表明，在95%置信限下结果差异不显著。
