Droplet Calibration Method
|
| |
Calibration is crucial. Use
multiple instruments, share data with collaborators, relate what you did
yesterday with what you plan for tomorrow, defend your claims in court
- the list is endless. The alternative is normalisation, but that wastes
information.
The AquaFlux is the only TEWL instrument to use the droplet
calibration method, which has been verified by an independent Standards
Laboratory (National Physical Laboratory, UK). Not only can the droplet
method be traced to fundamental measures, it has also been shown to bring
TEWL readings from different instruments closer into agreement.
No need to rely on proprietary calibration methods. No need to send your
instrument for re-calibration. You can check the calibration of an AquaFlux
yourself in about half an hour. We supply the micro-syringe and the software.
You supply 500nL of water. |

Use the micro-syringe supplied with your instrument to dispense a 500nL
water droplet into a closed calibration cap. Attach the
cap to the measurement chamber and press the red probe button. That's
it. The software displays the evaporated water quantity as a time-series
such as shown below. The calibration works by equating the evaporated
quantity with the quantity of water dispensed in the droplet.
