Stibine and bismuthine trapping in quartz tube atomizers for atomic absorption spectrometry - Method optimization and analytical applications

The compact quartz trap-and-atomizer device was employed to find optimum trapping and volatilization conditions for Sb and Bi hydrides. The trap-and-atomizer device can be replaced by conventional atom...
