Microbiological and IVF laboratories use CO₂ incubators or triple gas incubators (CO₂ and O₂) and their internal atmospheres must be continuously monitored to maximise cell or culture viability.
XiltriX uses a unique and accurate method of CO₂ monitoring as it does not just measure inside the incubator but transports a sample of the incubator atmosphere to a centralized measuring station. Samples from up to 16 incubators can be analysed by a single CO₂ sensor inside a CO₂ substation. Each sample channel is measured every 20 minutes and excess humidity is automatically removed by moisture separators. The internal CO₂ sensor is automatically calibrated using outside air (zero) and a calibration gas supply. This way the CO₂ measurement is always accurate regardless of drift of the CO₂ sensor or changes in outside conditions
O₂ monitoring uses the identical system but with a different type of sensor.
The sampling system uses a vacuum pump and a specialized valve bank. After the sample has been measured the value is sent to the XiltriX main system where it is treated like any value measurement. It is possible to set daily or weekly evaluation programs in the software. These programs offer the flexibility to make it possible to work comfortably during the day and to tighten monitoring during the night.
“A search was started to find a system that could measure multiple physical parameters i.e. CO₂ , temperature, differentials pressures and relative humidity. Also because of the more stringent legislation and accreditation needs for the International Joint Commission (IJC) the system had to comply to a large number of requirements.”
