cient.
Only wipe the housing with a soft, clean cloth which may be wetted with a commercially
available neutral cleaning agent if necessary.
8.1.2 Cleaning the sample block
WARNING
Risk of eye injury!
Wear safety goggles when blasting the sample block with compressed air.
Dust or reagent residue in the sample block can cause an increase in the background sig-
nal.
¡ Use compressed air to blow out the recesses in the sample block.

or ethanol. Let the liquid act for approx. 1min before sucking it out again. Repeat
the process until the background signal is in the normal range.
