INTRODUCTION

This analytical procedure is designed to measure the content of the elements (arsenic, barium, cadmium, cobalt, manganese, copper, iron, nickel, lead, strontium, and zinc) in seawater samples. Determination of the dissolved forms of the elements in samples with salinity up to 50‰ (including water from oceans and estuaries) is performed using MGA-1000 Graphite Furnace AA Spectrometer. The measurement ranges of the procedure cover all the specified maximum allowable concentration levels and provide accurate determination of the elements at the concentration levels close to natural.

Due to the advanced Zeeman background correction system of MGA-1000 the procedure does not imply laborious sample preparation and provides a simplified calibration procedure.
