摘要：

A unique micro-distillation unit has been developed as a module for continuous flow analyzers. It is compact and constructed entirely of stainless steel. Ammonium and nitrate nitrogen can be determined in a variety of digests or extracts without matrix effects. The unit has a good flow-through of 30 samples h-1 and in being a true distillation procedure, ammonia is determined interference free.
