New Version of Aulox System to Be Used in Chemical Processes during Next IMO Expedition

Friday, October 6, 2017

Specialists working at the Millennium Institute of Oceanography (IMO) participated in a two-week training program on the operation of the new version of the Aulox system. Engineer Victor Villagrán, director of Development and Technology Transfer at IMO, was in charge of this program.

“We wanted to communicate more details about the operation of this piece of equipment, with which we’ll be measuring dissolved oxygen during our next cruise, so the idea was that our team should be properly prepared to take on that challenge,” explained Villagrán. This is a significant challenge for IMO, since the expedition will be exploring the Atacama Trench, one of the deepest in the Southern Hemisphere.

Some of the course hours were spent on explaining the theory behind the functioning of Aulox, so that its mode of operation would be clear. The course also included chemical training, which is more directly related to the measurement of dissolved oxygen.

“Aulox is a machine that carries out tritrations automatically through an integrated detection unit, consisting of a UV light source and a photosensor,” explained Villagrán. Additionally, the machine has a processor that controls tritrations, its main characteristic being its high precision.

Aulox can automatically reach the oxygen measurement standard and can be used to study the ocean, but it was also designed to study any other body of water.

Eduardo Navarro, marine biologist and member of IMO, participated in the course and thinks that it was a great opportunity to increase support capacity among IMO members working together in the same team. “This idea has its origin in the need to operate this piece of equipment effectively, particularly as we are approaching a new expedition. Teamwork is extremely important, taking into account that other experts working in UdeC’s Department of Oceanography took part in the training because this is collaborative work,” he said.

It should be mentioned that Aulox was completely designed by Víctor Villagrán and his team and is now in the process of being patented.
