S108 Absolute O2 Analyzer is the most flexible, accurate and affordable oxygen analyzer on the market.  It uses a fuel cell sensor that operates at ambient temperature unlike power hungry zirconium sensors that require an on-board furnace.   The sensor incorporates  acid electrolyte and teflon diffusion membrane.  Measurements of pO2 are precise across the entire range from 0% to 100%. For animal and human respirometry, the S108 Absolute O2 Analyzer can be used with our S158 CO2 Analyzer to measure respiratory quotient. For respirometry in smaller or less active organisms, it may be configured in a stop flow or closed gas exchange system. Calibration is easy.  All you need is dry ambient air (use a N2 zero gas for most stringent measurements). Linearity is maintained across the entire dynamic range.  We recommend using S108  with our C950 Gas Exchange Software or other data acquisition software.

Features:

• 0.01% resolution on digital display ­ and much better in software (50ppm)
• Accuracy 0.21% full scale
• Switchable ranges of 0-25% and 0-100% O2

• response time (90%) 12 sec
• Integrated pressure sensor
• O2 output displayed in % or kPa Pressure pressure output displayed (kPa)
• Optional battery pack for field use
• Built in Temperature compensation
• Weatherproof case

The S108 Oxygen Analyzer is one of the least expensive oxygen analyzers on the market. The fuel cell sensor is easily replaced by the user when necessary (approx. every 2 to 3 years depending on use).

Qubit Systems’ Q-S102 O2 Analyzer is configured for measuring oxygen concentration in a flow through gas exchange systems in 0-25% or 0-100% range with 0.21% accuracy. The Q-S102 O2 Analyzer is ideal for determining O2 uptake in organisms with high metabolic rates in an open flow system configuration.  For organisms with low metabolic rate it can be used in a closed flow system where the rate of O2 uptake  can be calculated from the slope of O2 decline in the system.  Q-S102  has been developed from the S102 Flow Through O2 Sensor and is a key component of the New Q-Box Packages for both research and teaching.  The following packages include the Q-S102: Q-Box RP1LP Low Range Respiration Package, Q-Box RP2LP High Range Respiration Package, Q-Box NF1LP Nitrogen Fixation Package and Q-Box HR1LP Human Respirometry Package.

The Q-S102 O2 Analyzer has a galvanic cell (a lead-oxygen battery) consisting of a lead anode, an O2 cathode, and an acid electrolyte.  It also incorporates an O2-permeable Teflon FEP membrane with a gold electrode bonded to its surface.  Oxygen diffusing through this membrane is reduced electrochemically at the gold electrode. A resistor and thermistor (for temperature compensation) are connected between anode and cathode.  The output of the instrument is proportional to the current flowing through the resistor and thermistor and this is proportional to pO2 in contact with Teflon membrane.

Specifications:

Additional Features:

• Simple 2 point calibration
• Output linear over the entire calibration range
• 90% response in twelve seconds

This enables the user to follow changes in these variables as they occur during the various experimental procedures.  Exhaled air is sub-sampled from a mixing volume and pumped through the gas analysis system at a known flow rate. From the data tidal volume, VE, VO2, VCO2 and respiratory exchange ratio can be calculated.

 Q-Box HR1LP Human Respirometry Package can be used for measurements of:

• VO2 and VCO2 during rest and exercise
• Heart rate
• Tidal Volume
• Minute Volume
• Breathing Frequency

CO2 and O2 are monitored continuously in mixed expired air, so that changes in VO2 and VCO2 can be monitored with time and under changing conditions.

Example of experiments with Q-Box HR1LP Human respirometry Package:

• Effects of isotonic exercise on VE, VO2, VCO2 and respiratory exchange ratio
• Effects of hyperventilation and breath holding on respiration and heart rate
• Effects of re-breathing and increased dead space on respiration and heart rate
• Effects of diet, caffeine, etc. on metabolism

The Q-Box HR1LP package can be easily adapted for use as Q-Box RP2LP High Range Respiration Package by adding the G114 Animal Chamber.  As such it can be used for investigations of respirometry in mice and other small animals.

Example of data from Q-Box HR1LP experiment involving a subject at rest, on a stationary bike and at rest again.

Qubit’s new BBB1LP Breath by Breath Respirometry Package is designed to measure both steady-state and dynamic changes in human metabolic rate under a variety of test conditions.
