An atomic absorption spectrometer is an instrument which is used to analyze the concentrations of metals in solution. Sixty eight elements can be determined directly over a wide range of concentrations from ppb to percent levels, with good precision–typically better than 1 % RSD. Sample preparation is generally simple and frequently involves little more than dissolution in an appropriate acid. The instrument is easy to tune and operate.详细>
