我们首次推出一种新的产品线，能够对许多水化学参数进行高精度的原位测量：即，淹没在环境中，包括深海（至6，000米）。该产品基于国家海洋学中心（NOC）和南安普顿大学的原位实验室芯片技术开发，并由Clearwater Sensors Ltd.许可生产，作为一家初创企业和工业合作伙伴，我们致力于将这项技术推向全球，并进一步开发其潜力。该技术已经由NOC及其全球合作伙伴部署了200多次，包括在浑浊的河口和河流中接近4，800米的深度，以及在北极季节性冰雪覆盖地区长达一年。该技术能够准确确定需要试剂并产生电、吸光度、荧光或发光信号的化学和生物参数。因此，它适用于广泛的环境测量。虽然该合作伙伴关系正在开发更多参数，但硝酸盐，亚硝酸盐，磷酸盐，硅酸盐，铁和pH传感器目前已上市。这些传感器使用微流体和光学器件结合在一个光电流芯片上，机电阀和泵安装在它上面，以混合水样与试剂和测量光学响应。本文概述了传感器及其基本组件和技术，并举例说明了与滑翔机、自主水下航行器和系泊装置等观测平台的部署和集成。
We introduce for the first time a new product line able to make high accuracy measurements of a number of water chemistry parameters in situ: i.e., submerged in the environment including in the deep sea (to 6,000 m). This product is based on the developments of in situ lab on chip technology at the National Oceanography Centre (NOC), and the University of Southampton and is produced under license by Clearwater Sensors Ltd., a start-up and industrial partner in bringing this technology to global availability and further developing its potential. The technology has already been deployed by the NOC, and with their partners worldwide over 200 times including to depths of similar to 4,800 m, in turbid estuaries and rivers, and for up to a year in seasonally ice-covered regions of the arctic. The technology is capable of making accurate determinations of chemical and biological parameters that require reagents and which produce an electrical, absorbance, fluorescence, or luminescence signal. As such it is suitable for a wide range of environmental measurements. Whilst further parameters are in development across this partnership, Nitrate, Nitrite, Phosphate, Silicate, Iron, and pH sensors are currently available commercially. Theses sensors use microfluidics and optics combined in an optofluidic chip with electromechanical valves and pumps mounted upon it to mix water samples with reagents and measure the optical response. An overview of the sensors and the underlying components and technologies is given together with examples of deployments and integrations with observing platforms such as gliders, autonomous underwater vehicles and moorings.
