Breathing Air Analysis
Ensuring the air you breath is safe.
Our main aim is to provide you with the confidence and peace of mind, that the air you are breathing is safe.OEMA will carry out your analysis with precision and accuracy, ensuring a fast, reliable service.
We test in accordance with varying customer needs, ranging from British Standards to Defstan for the military. This particular aspect of our services takes us across the globe, supporting our Royal Naval defence fleet, where timing, accuracy and commitment are critical.
The analysis is carried out using FTIR. FT-IR stands for Fourier Transform InfraRed, the preferred method of infrared spectroscopy. In infrared spectroscopy, IR radiation is passed through a sample. Some of the infrared radiation is absorbed by the sample and some of it is passed through (transmitted). The resulting spectrum represents the molecular absorption and transmission, creating a molecular fingerprint of the sample. Like a fingerprint no two unique molecular structures produce the same infrared spectrum. This makes infrared spectroscopy useful for several types of analysis.
Advantages of FTIR Spectroscopy
Advantages of FTIR Spectroscopy for Breathing Air Analysis
- Uncertainty of measurement circa +/-2%.
- Calibration to National Standards checked daily.
- Known and calibrated analytes have concentrations determined by computer software. Unknown contaminants are analysed by highly qualified staff in laboratory conditions. Carried out by an independent laboratory.
- Full spectrum analysis. Over 300 contaminants can be monitored in a single pass.
- Fully compliant with BS-EN12021:2014.
- Meets COSHH obligations with ease.
- No initial cost.
- Permanent record. As the scan is computer generated it can be stored indefinitely, to be available for scrutiny. Therefore, provides genuine evidence to support litigation.
- Value for money. Very low cost for such a sophisticated method.
- No disposal requirements.
- No consumable costs.
