Biopac GASSYS2 -RB (1L) or -RA (5L) CO2 and O2 Gas Analys

Obtain real-time Oxygen Consumption (VO2) and Respiratory Exchange Ratio (RER) measurements using a BIOPAC data acquisition system with the GasSys2 module and some air flow accessories.

  • 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.

The GasSys2 measures expired O2 and CO2 concentrations.

  • When the subject inspires, air will be drawn into the GasSys2 through the TSD117 air flow transducer. The TSD117 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. The GasSys2 is designed to work with saturated expired air.

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.

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.

Applications Include:

  • Exercise Physiology
  • Pulmonary Function

GASSYS2 Specifications:

O2 sensor: Warm-up: 10 minutes
Response time 10-90%: 30 sec.
Accuracy: 1% FSR (full scale range)
Zirconia solid electrolyte with a 0.1-25% sensing range and an estimated 5-year lifetime. It runs hot, which burns off humidity.
CO2 sensor: Warm-up: 2 minutes
Response time 10-90%: 45 sec.
Accuracy: 3% FSR (full scale range)
Uses a humidity-repellant (hydrophobic) membrane and has a sensing range of 0-5%. It uses non-dispersive infrared diffusion with single-beam IR and a self-calibrating algorithm. It also runs hot, which burns off humidity.
Calibration: Sensors are factory calibrated prior to shipping.
Power: 12 VDC @ 1 amp wall adapter.
Accessories: Ships with AFT7 smooth bore tubing, AFT11E flexible coupler, and AFT22 non-rebreathing T-valve; see AFT Series for additional accessories.
Chamber: GASSYS2-RA 5 litres
Chamber: GASSYS2-RB 1 litre
