AIS has just developed a new portable electrochemical / HPLC system that can be deployed at full ocean depth.  The instrument can also be used on land to perform fracturing fluid analysis in real time.

To the left is a lander instrument for in-situ electrochemical research of the sediment on the sea floor.  The AIS ISEA™, AIS-INSEA™IV, in-situ electrochemical analyzers, allow researchers to collect valuable data on oxygen, sulfide, iron and manganese to name a few in extreme field applications.

Our patent pending ISEA, in-situ electrochemical analyzers allow the user to collect data simultaneously from a variety of sensors. Voltammetric, potentiometric, and amperometric data, along with other sensor data, can all be collected at the same time.  The user can access the instrument from multiple platforms over the internet facilitating easy data downloads and instrument control. 

This instrument has been used in field applications in areas such as marshes, salt or fresh water columns, ocean sediments, geysers in Yellowstone, Antarctic glaciers, and at deep-sea hydrothermal vents. Well monitoring and chemical synthesis monitoring in laboratory or industrial settings can also be easily performed with these systems.

This is a deployment of an electrochemical analyzer, the AIS ISEA II.  This instrument performs standard analytical electrochemical analysis in-situ.






This deployable instrument is the AIS ISEA LC,  The first electrochemical analyzer coupled to a complete HPLC analyzer for in-situ analysis.  The instrument can perform voltammetric analysis of sulfide, oxygen, iron, manganese and all the anions via ion chromatography. This instrument performs all its measurements autonomously once being programed on the surfure prior to deployment.  The instrument is powered by a 12 volt battery system seen in the background.  This lander is also equipped with a syringe water sampler, an AIS micro manipulator, and benthic chamber.
