<p>An atomic absorption spectrophotometer, comprising a combined light source, a detection device, a flame atomization device, a hydride generation device and a graphite furnace atomization device. The axis of the flame atomizer (5) in the flame atomization device, the axis of the hydride atomizer (6) in the hydride generation device and the axis of the graphite furnace atomizer (8) in the graphite furnace atomization device are respectively positioned in line with the light axis (7) of the combined light source by an adjustment device. The atomic absorption spectrophotometer disclosed combines three types of atomizers, allowing for direct, fast and efficient detection of microelements, trace elements and such elements as mercury, arsenic, selenium and the like in one atomic absorption spectrophotometer with simple and easy operation.</p> |
