Ammonia

  氨 (NH3) 是一种天然存在的化合物,由一个氮原子和三个氢原子构成,氮原子和三个氢原子之间由共价单键进行结合。氨通常为无色,是大气中最丰富的碱性气体。氨通过土壤固氮细菌和海洋藻类,以及植物、动物和动物粪污的分解作用自然产生。

  数千年来,生物体、土壤和大气之间的氮交换一直处于平衡状态。然而,人类从事的工业活动已经造成氨呈现显著增加趋势,而氨又是氮循环的重要组成部分。这种增加趋势主要来自是肥料中的氨,它是粪肥管理的副产物。氨含量增加可能会产生破坏性环境影响,例如在大气中,氨促成了颗粒物的形成。在地球表面,氨可以泾流形式进入水源,从而降低水质并损害生态系统(例如通过营养物富集)。因此,精确测量氨的含量可以帮助我们了解并缓解对氮循环的人为影响。

  Picarro 设计并生产的两款气体浓度分析仪,能够针对实验室研究应用和现场研究应用来实现氨含量的精确测定。

G2508 气体浓度分析仪

Picarro G2508 气体浓度分析仪可同步测量氧化亚氮 (N2O)、甲烷 (CH4)、二氧化碳 (CO2)、氨 (NH3) 和水汽 (H2O) ,灵敏度为十亿分率 (ppb),针对农业与土壤科学、生态学和量化排放应用所产生的漂移可忽略不计。

G2509 气体浓度分析仪

  Picarro G2509 气体浓度分析仪设计用于畜牧业、粪便处理和肥料研究领域。在这些充满挑战性的环境中,高浓度的环境甲烷和氨气动态变化快,导致难以精确测量氨气和温室气体。

SI2103 气体浓度分析仪

The Picarro SI2103 gas concentration analyzer delivers ultra-precise and stable measurements of ammonia (NH3) with a parts-per-trillion (ppt) lower limit of detection (LOD) and negligible drift. It is the ideal solution for urban and atmospheric air quality monitoring, studies of particulate matter formation, livestock emission quantification, vehicle emission quantification, indoor air quality and other applications.
