Gas analysis O2 and CO2
Integration with fermenters
The Tandem gas analyzer can be integrated with almost all fermenters via RS232, 4-20mA or 0-20mV output signal.
Stand alone or multiplex
The Tandem gas analyzer series consists of 2 models, PRO which can measure on 1 fermenter and Multiplex which can measure on up to 12 fermenters.
Simple CO2 and O2 measurement
The equipment makes it possible to follow the O2 and the CO2 development in the fermentation online and thus continuously to adjust the control according to how the cells are growing.
H.E.L Group is a British company which manufactures the gas analyzer series Tandem. The instrument is designed to measure CO2 and O2 in the exhaust gas from fermenters. Aage Christensen has cooperated with H.E.L Group since 2008, and in this period we have integrated more than 60 gas analyzers to fermenters at different companies in Denmark.
Tandem gas analyzer
A Tandem gas analyzer gives real-time, online data, which helps customers understand and control their cell culture experiments.
The instrument is specifically designed for CO2 and O2 exhaust gas analysis from cell culture experiments and thus fits onto a wide range of systems from different manufacturers.
