一个独立的传感器系统与集成的子系统进行了演示。该系统是便携式的，并能够在原位试剂为基础的营养分析。该系统基于低成本的光学检测方法，以及能够检测亚硝酸盐的自动化微流体递送系统，检测限（LOD）为15 nM。传感器在南安普顿码头原位运行57 h（2010年12月），进行了375次测量。(C)2011 Elsevier B.V.保留所有权利。
A stand-alone sensor system with integrated sub-systems is demonstrated. The system is portable and capable of in situ reagent-based nutrient analysis. The system is based on a low cost optical detection method, together with an automated microfluidic delivery system that is able to detect nitrite with a limit of detection (LOD) of 15 nM. The sensor was operated in situ at Southampton Dockhead for 57 h (December 2010) and 375 measurements were taken. (C) 2011 Elsevier B.V. All rights reserved.
