Gas Analysis Systems – CO2 and O2

The Gold Standard for Better Science and Greater Discovery

Real-time VO2 and RER

CO2 and O2 Gas Analysis System for MP, 5 L
Part #: GASSYS2-EA, GASSYS2-EB

Obtain real-time Oxygen Consumption (VO2) and Respiratory Exchange Ratio (RER) measurements using a BIOPAC data acquisition system with the Gas Analysis module and some air flow accessories.

Measure expired O2 and CO2 concentrations.

  • When the subject inspires, air will be drawn into the GASSYS2 through the SS11LA/B air flow transducer, which is placed on the inspiration side to eliminate any effects associated with expired air humidity.
  • When the subject expires, air will be directed to the GASSYS2 module, which is designed to work with saturated expired air.

Details

Compatibility


The non-rebreathing “T” valve directs only expired air to the GASSYS2. Because only expired air is directed to the module, the system acts to average respiratory outflows. This averaging effect causes the CO2 and O2 concentrations to vary in accordance to the mean values resident in a few expired breaths.

Options

Each chamber assembly includes the chamber casing and rod. The chambers work exactly the same way and are interchangeable on the module base. Use the 1.7 L chamber for small children/medium sized animals.

Ships with AFT7 smooth bore tubing, AFT11E flexible coupler, and AFT22 non-rebreathing T-valve. See AFT Series for other air flow and gas analysis accessories.

Chamber Options
Two chamber sizes are available for the GASSYS2. Each chamber assembly includes the chamber casing and rod. The chambers work exactly the same way and are interchangeable on the module base. Use the smaller chamber size for small children/medium sized animals.

  • 5-liter chamber: included in the GASSYS2-RA; Order the chamber only as RX-GASA
  • 1-liter chamber: included in the GASSYS2-RB ; Order the chamber only as RX-GASB
