7.3 Validation Precautions
7.3.1 Environment
Instrument performance may be affected by abrupt changes in ambient temperature such as
drafts from heating and air conditioning vents.
The equipment should be installed in a room with minimal (< 2 °C) temperature fluctuation
and away from sources of drafts and air currents.
7.3.2 Installation Site
The installation site is very important for ensuring correct validation. The site should satisfy
the following conditions:
WARNING
• Provide ample ventilation with no fire sources in vicinity
When flammable or toxic solvents are used as the mobile phase, the room must be
properly ventilated. When flammable solvents are used, open flame or other fire
sources must be strictly prohibited.
• Precautions for use of the low-pressure Hg (Mercury) lamp
Install the low-pressure Hg (Mercury) lamp before turning on the power of the lamp.
