Ma Yuping (Analysis and Testing Center of Xinjiang, Wulumuqi 830011)
Using a gold coated graphite tube, a sample insertion system for hydride generation graphite furnace atomic absorption spectrometer and a continuous flowing appliance of hydride generation in this labora tory. Trace mercury in grain, plant and water is directly determined. This method is simple and convenient! good precision and high accuracy with sensitivity of 1. Ing/L and detection limit of 0. 8 ng/L.
