Exhaled Breath Analysis Equipment Calibration

In recent years there has been an increase in the number of patients being referred and tested for breathing related illnesses. Various types of medical equipment are utilised to diagnose either the type of disorder or the severity of the disease itself.

We have developed a specific range of gas mixtures that can be used to calibrate or test equipment associated with exhaled breath. Typically these mixtures are used in spirometry (lung function), carbon monoxide, fractional exhaled nitric oxide and hydrogen breath testing.

We understand the critical importance of the accuracy of results given by the medical equipment, which is why users rely upon our gas mixtures for these exacting applications.

How many tests can be performed using each canister?

The instrument manufacturer normally states the gas flow rate required in their operating procedures. Air Products' largest canisters hold approximately 110 litres, so an instrument with a response time of 10 seconds using a fixed flow of gas of 1.0 lpm might be tested several hundred times using the 110L canister.
