Charged Aerosol Detectors

Corona Veo and Corona Veo RS

Page 6 Operating Instructions

• Always replace blown fuses with original spare part fuses authorized by Thermo Fisher

Scientific.

• Replace faulty communication cables.

• Replace faulty power cords. Never use a power cord other than the power cords provided

for the device.

• Use only the original spare parts and accessories authorized for the device by Thermo

Fisher Scientific.

• When operating the HPLC system, always set a lower pressure limit for the pump. This

prevents damage resulting from leakage or from running the pump dry.

• To prevent damage to the detector when lifting or moving, always lift the unit by the

bottom sides or sides. Do not lift the detector by the bottom front or front panel door.

This may damage the door.

• After operation, rinse out buffers and solutions that form peroxides.

• Before switching from buffer to organic solution, rinse the analytical system thoroughly

with deionized or HPLC grade water.

• When switching to another solvent, ensure that the new solvent is miscible with the one

contained in the HPLC system. If the solvents are not miscible, the system can be

damaged, for example, by flocculation.

• If a leak occurs, turn off the detector immediately, stop the pump flow, and remedy the

situation.

• Use only standard solvents (HPLC grade) and buffers that are compatible with all parts

that may be exposed to solvents.

• Before interrupting operation for several days or more or when preparing the detector for

transport, observe the precautions for shutting down the detector (→ page 74).

• Do not use the detector in ways other than those described in these Operating

Instructions.

• Keep the operating instructions near the device to be available for quick reference.
