Description: A simple atomic emission spectrometer , which allows to perform express determination of sodium in the water. Uof spark atomization is novelty, allowing us to make the unit very compact compared to industrial designs. The selected scheme for calculating the spectrum showed its extreme simplicity and universality. The device was fabricated and investigated the composition of mineral waters. The results obtained correspond to reality. The possibility of its use for such a task category was shown.
