GSA series of On-Line gas stream analyzers are available for continuous and intermittent monitoring of modified atmosphere packaging (MAP) and other gas flushing operations. Six new models are available for the analysis of O₂, CO₂, and combination O₂/CO₂ concentration levels. An optional sampling device (patented) allows the new GSA units to directly sample the filling chamber in intermittent MAP packaging applications. The GSA units were specifically designed to ease the integration task for plant personnel, OEM's and value-added resellers by offering programmable logic controller (PLC), RS-232 and analog outputs. An optional feature on the GSA units allow for sampling of dual gas streams by one unit. These systems incorporate MOCON's exclusive FLO-SMART™ electronic flow sensing technology.

Typical applications for the GSA systems include: modified atmosphere and snack food packaging, bakery, meat and cheeses, coffee/juice/carbonated beverages, glove boxes and purge gas, controlled environment and gas blanket monitoring.
