CO2 and O2 Gas Analysis System
Part #: GASSYS3

New! Gas Analysis System—paired with an MP36 unit, airflow transducer, and accessories—provides a lower-cost, compact, simpler, solution suitable for both education and research physiology applications. Obtain quality metabolic data, such as Volume of Oxygen Consumed (V̇O2), Volume of Carbon Dioxide eliminated (V̇CO2), Respiratory Exchange Ratio (RER), Energy Expenditure (EE, REE) and Resting Metabolic Rate (RMR) from Subjects at rest or during exercise.

GASSYS3 solves a myriad of challenges traditional methods of obtaining metabolic data often present, including high cost, extensive, complex and costly calibration requirements, and difficult operation.

Details

Compatibility


The BIOPAC GASSYS3 provides detailed insights on human subjects’ responses in a variety of research applications, such as exercise physiology, sports science, biomedical engineering, psychophysiology, and many product development and consumer neuroscience applications.

GASSYS3 Benefits

  • CO2 sensor range extended from 5% to 10%, important for VO2 Max measurements.
  • Integrated heater lowers the relative humidity to prevent condensation from forming in and around the sensors.
  • Integrated environmental sensors for both ambient and chamber air. These sensors are read in serially by the MP36 (under software control) and are used to adjust measurements based on changes in temperature, relative humidity, and barometric pressure.
  • Small blower inside chamber, which helps mix the air, improves CO2 sensor response time and helps prevent condensation inside the CO2 sensor.
  • Sealed Chamber prevents ambient air from corrupting the chamber air between expired air cycles.
  • New design results in less air restriction.
  • Auto-voltage calibration and memory circuitry added to the O2 and CO2 circuits to improve accuracy.

Measure expired O2 and CO2 concentrations

  • The non-rebreathing “T” valve directs only expired air through the GASSYS3, which is designed to work with saturated expired air. The mixing chamber portion of the GASSYS3 acts to average respiratory outflows. This averaging effect causes the CO2 and O2 concentrations to vary in accordance with the mean values resident in multiple expired breaths.
    • For resting measurements, the airflow transducer can be placed on the output port of the GASSYS3.
    • For exercise measurements, the airflow transducer is placed on the inspired side of the T-valve to reduce the chance of condensation affecting airflow accuracy.

Compatibility

GASSYS3 works with MP36 with BSL 4.1.3 or above OR MP36R with AcqKnowledge 5.0.3 or above; not compatible with MP45.
