metadata.name: dc.description.abstract
metadata.value: A novel automatic stepwise injection headspace single-drop micro-extraction system is
  proposed as a versatile approach for automated determination of volatile compounds. The system
  application is demonstrated for ammonia determination in concrete samples. An ammonia gas
  was produced from ammonium ions and extracted on-line into 5 L 0.1 M H3PO4 to eliminate the
  interference effect of concrete species on the ammonia stepwise injection spectrophotometric
  determination. The linear range was 0.1 to 1 mg kg-1 with LOD 30 μg kg-1. The sample
  throughput was 4 h 1. This system has been successfully applied for the determination of
  ammonia in concretes.
