Replacing the Flow Cell
Prerequisite
Detector has been switched off.
Power plug has been pulled.
Capillaries are disconnected.
Replacing the Fiber Optic
UV light will cause the optical fiber to become blind with time
(solarization), making them no longer suitable for use.
Observe the following regarding the use of UV fiber optics:
Do not touch the ends of the fiber optics with your fingers, as
this could falsify the measurement.
Handle the fiber optics with care, avoid impacts or hard
actions.
Move the fiber optics carefully without using pressure or
bending it.
