7.9

Cleaning the optical plasma interface (OPI) (Multiview EOP
only)

Caution! Damage to instrument!



The load coil is very sensitive.



Make sure not to hit the load coil when removing the OPI.

Proceed as follows to clean the OPI:

Removing the OPI

, see page 55.

Cleaning the sampler

, see page 57.

Cleaning the lens

, see page 58.

Installing the lens and the OPI

, see page 59.

7.9.1

Removing the OPI

Warning! Hot surface!

The plasma torch, plasma interface, and load coil may be very hot.



Let the components cool for 10 to 15 minutes before commencing work on
them.



When working on the plasma torch, plasma interface, and induction coil,
wearing protective gloves and safety goggles is mandatory.

Warning! Risk of injury

Glass parts may break when handled incorrectly and cause cutting injuries.



When working on the sample introduction system, wearing protective gloves
and safety goggles is mandatory.



If glass is broken, a suitable container (bucket) must be used to collect the
larger pieces first. In order to remove small parts and glass fragments, a
suitable vacuum must be used
