摘要：

A comparison of five kinds of hydride generator/gas-liquid phase separator systems used in the hydride generation in AAS is made. These systems are also compared with a newly designed type of separator. Optimum working conditions were tested and basic characteristics were measured for all the types of systems. The basic criteria for comparison of the systems were the measuring sensitivity, reproducibility and detection limit for the given system. Additional comparison criteria were the analysis frequency achieved, applicability of the given separator for flow-injection measurements and economic criteria.
