Gas Standards for Medical Diagnostic and Leak Detection Monitors
Standard gas mixtures are an accurate and cost-effective method for calibrating medical diagnostic monitors for blood gas, lung diffusion and leak detection monitors. They are stable and provide a repeatable reference concentration that can be used for regular calibration of monitors.
Each standard contains accurately-weighed components.
Mixtures are available for calibrations of monitors with the following components:
|
Medical Diagnostic / Leak Detection |
||
|
Gaseous Species |
Matrix |
Amount Fraction Range (mol/mol) |
| Carbon dioxide | Oxygen | 50×10-2 – 500×10-6 |
| Carbon monoxide / Oxygen / Helium | Nitrogen / Air | 50×10-2 – 500×10-6 |
| Sulphur hexafluoride | Nitrogen | 50×10-4 – 500×10-9 |
| Helium | Nitrogen | 50×10-3 – 500×10-6 |
NPL's gas standards are certified for a period up to five years depending on the stability of the mixture. NPL offers a cost-effective re-certification service after the initial certification period has expired, ensuring temporal consistency of gas traceability.
