dc.description.abstract | 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. | en_GB |
