1.5 Safety precautions and conditions for safe use
WARNING!
Before installing or performing any maintenance on the analyzer, read and understand the
safety information given in the preliminary information of this manual.
The analyzer described in this manual has been quality control tested and left the
manufacturer in pristine condition. To achieve the correct and safe operation of this
product, it must be transported, installed, operated, and maintained as described by the
manufacturer.
All lasers used within the instrument are Class 1. The emitted laser light is invisible (mid-
infrared) and the pulse duration so short that the unprotected eye will not be damaged.
The nature of the laser beam path and beam width further ensures that it should be
impossible to cause any eye damage. The instrument has warning labels at appropriate
positions in accordance with USA 21 CFR 1040.10.
