Compressed Breathing Air Analysis Kit
Impurities in breathing air can adversely affect human health. REFLEX Analytical has responded with a Compressed Breathing Air Analysis Kit to assure accurate measurements of the five common contaminants (Carbon Monoxide, Carbon Dioxide, Oil Mist, Water Vapor and Oxygen) before respiratory harm is caused. The Compressed Breathing Air Analysis Kit is critical for anyone involved with filling, purification, generation or usage of compressed breathing air. The kit is designed to easily measure contaminates within minutes from SCBA, SCUBA and other pressurized breathing air cylinders, as well as directly from the outlet of an air compressor or purifier. This is a development which complements REFLEX Analytical's series of gas cells used for spectroscopic analysis.

The order details below for the Compressed Breathing Air Analysis Kit includes one maximum 3000 psig cylinder inlet connection (specify CGA 346, CGA 590, 1/4" NPT male, SCUBA or Schrader), pressure regulator, flowmeter, flow bypass valve, timer, detector tube cutter, adjustable wrench, 50ml syringe with tubing for use with the Oxygen detector tube, hard shell carrying case and instructions. The detector tubes as referenced in the following grid are sold separately.

After connecting the Compressed Breathing Air Analysis Kit assembly to the compressed breathing air source to be analyzed, the breathing air is passed through each detector tube at a specific pressure, flow rate and time interval. Each detector tube is made with high purity reagents that absorb and react with the target component. The reaction causes a colorimetric stain whose length is proportional to the componentís concentration. The actual concentration is read directly from the measurement scale printed on the detector tube.

To appreciate the importance of breathing air quality CLICK HERE and read a detailed report from the Environmental Health Laboratory (EHL) at the University of Washington. In addition to the results from their testing, the EHL provides generalized guidance for breathing air quality assessment, avoidance of problems, and problem solving. Information on regulated contaminants is presented for a better understanding of breathing air quality regulations. A summary of contaminants and their affects are elaborated below.

Carbon Monoxide
Poisoning occurs after breathing in too much Carbon Monoxide. Symptoms of mild acute poisoning include lightheadedness, confusion, headache, feeling like the world is spinning, and flu-like effects. Larger exposures can lead to toxicity of the central nervous system and heart, and death. After acute poisoning, long-term problems may occur. Chronic exposure to low levels of carbon monoxide can lead to depression, confusion, and memory loss.
Carbon Dioxide
Low concentrations are not harmful. Higher concentrations can affect respiratory function and cause excitation followed by depression of the central nervous system. A high concentration can displace Oxygen in the air. If less Oxygen is available to breathe, symptoms such as rapid breathing, rapid heart rate, clumsiness, emotional upsets and fatigue can result. As less Oxygen becomes available, nausea and vomiting, collapse, convulsions, coma and death can occur. Symptoms occur more quickly with physical effort. Lack of Oxygen can cause permanent damage to organs including the brain and heart.
It may seem counterintuitive that Oxygen content in compressed breathing air even need be sampled because air intakes located outdoors should contain 20.9% oxygen since that is its concentration in ambient, atmospheric air. OSHA and NIOSH define an Oxygen-deficient atmosphere as any atmosphere containing Oxygen at a concentration below 19.5% at sea level, which includes a safety factor. At concentrations below 16%, decreased mental effectiveness, visual acuity, and muscular coordination occur. Below 10%, loss of consciousness may occur; below 6%, death results. Individuals exposed to low concentrations of Oxygen are often unaware of the growing danger, because only mild perceptional changes are initially experienced. Oxygen toxicity may result from exposure to elevated concentrations of oxygen (> 50%) at normal pressures; delayed symptoms begin with inflammation of the upper airways and can progress to acute respiratory distress syndrome. Hyperbaric Oxygen exposure can lead to central nervous system toxicity in divers; symptoms can include visual disturbance, ear problems, dizziness, confusion, nausea, and seizures. Safety procedures have been developed for divers using high percentages of Oxygen or hyperbaric Oxygen.
Water Vapor
While water vapor and liquid water are not directly harmful to users of breathing air, excessive amounts can cause hazards. Moisture can corrode breathing air systems and reduce the efficacy of gas purifiers. A greater hazard is ice blockage of regulators in cold temperature conditions, whether on land or during cold water diving. As gas expands from the breathing air tank, it cools. If the dew point is reached, moisture will condense and then freeze when the surrounding temperature is low, thus blocking the air supply.
Oil Mist
Exposure to oil mist for a prolonged period of time can cause a number of health issues leading to nose and throat irritation, bronchitis, bronchial asthma, chronic cough and other respiratory issues.
