INFRARED SENSING OF CONCENTRATION OF METHANOL'S AQUEOUS SOLUTION

摘要

Systems and methods for infrared sensing a compound's concentration in aqueous solution are provided. In various non-limiting embodiments, the invention provides infrared [303] sensing [404] of methanol's concentration in aqueous solution in connection with a fuel circulation process for a direct methanol fuel cell [206]. In some embodiments, flow-through infrared sensing technique are provided. In other embodiments, window type infrared sensing techniques are provided. As a result of the infrared sensing, an accurate real-time measurement of the concentration of a compound of interest in aqueous solution is affordably obtained.
