2.4. Optical Sensors
Hyperion Fluorometers are configured and correlated with a specific fluorophore. This is identified
by the letter after the 5-digit serial number and is clearly engraved on the instrument housing
An optical sensor must be kept clean to operate correctly. Ensure that the SWiFT is power down
before cleaning the sensor.
Use warm soapy water with a soft bristled brush to remove any light fouling
For heavy fouling use a solvent (e.g Isopropyl alcohol) and a soft bristled brush
Always rinse thoroughly after every use.
2.4.1. Safety Statement
The fluorometer installed in the fastCTD is classified as Risk Group 1 under standard EN62471. As
the type is classified as Risk Group 1 solely due to radiation in the visible band a hazard label is not
required. However,
·
the LED used is in excess of the Exempt Group and that the viewer-related risk is dependent
upon how the user installs and operates the equipment.
·
the exposure hazard value (EHV) for a Valeport Fluorometer in terms of distance is 320mm
Never look directly into the aperture of the Fluorometer
