摘要：
The application of electrothermal atomization techniques for atomic absorption spectroscopy has increased many fold in recent years. Along with this widespread application, matrix interferences in pulse-type electrothermal atomizers have been observed. Until recently, very few interference studies have involved constant temperature electrothermal atomizers. In this paper a comparison is made of interferences in pulse-type vs constant temperature atomizers for various metal chlorides on the Mn atomic absorption signal. The results show no interferences in the constant temperature system while significant matrix interferences are observed in the pulse type unit.
