AB  - In this work, a portable and reliable optical emission spectrometric (OES) 
      instrument based on solid acid hydride generation (HG) and subsequent in situ 
      dielectric barrier discharge (DBD) preconcentration was first developed for 
      simultaneous and field analysis of ultratrace As and Sb in environmental water. 
      In situ DBD fulfilled both gas phase enrichment (GPE) and excitation; effective 
      enrichment made it possible to use a low-cost charge coupled device (CCD) as 
      detector. To simplify field protocol, solid tablet made from sulfamic acid was 
      first used to replace hydrochloric acid for co-generation of As and Sb hydrides. 
      Moisture interference was eliminated by carrier gas sweeping without any 
      desiccant. After calculating peak volume for emission data handling, detection 
      limits (LODs) were 0.5 mug L(-1) for As and 0.2 mug L(-1) for Sb, respectively, 
      with <3% relative standard deviations (RSDs) at 10 mug L(-1); linear dynamic 
      ranges (R(2)>0.995) were 2-200 mug L(-1) for As and 1-200 mug L(-1) for Sb, 
      respectively. The results agreed with certified values of CRMs and recoveries 
      were 87-97% vs. inductively coupled plasma mass spectrometry. The running costs 
      can be controlled within one dollar per use. This HG-in situ DBD trap-OES scheme, 
      with demonstrated advantages in sensitivity, low-cost, power (<60 W), size 
      (0.6 m x 0.5 m x 0.3 m), weight (15 kg), gas consumption (300 measurements per 
      4 L tank), and multi-element capability, was implemented in a miniature 
      spectrometer for field analysis.
