2Precautions
Handling Solvents Correctly
CAUTION
Organic and aqueous solvents can be hazardous if handled improperly. Always follow
the precautions listed below to protect both operator and instrument:
• Read the Material Safety Data Sheet (MSDS) for each solvent used.
• Prepare samples and transfer acids under a fume hood with adequate extraction.
• Wear gloves when handling acids or solvents.
• Wear safety glasses when handling any liquids.
• Cover volatile samples to minimize exposure to fumes and possible explosion
hazard.
• Clean any spillage immediately using the approved laboratory procedures.
• Store and prepare samples away from the instrument to prevent corrosion.
• Use peristaltic pump tubing that is compatible with the sample solvent being
pumped. For more information, refer to Chapter 6, “Technical Information”.
• Solvent spillage into instrument: please call the customer contact center.
Acid digestion at atmospheric or increased pressure require these additional
precautions:
• Apply heat slowly, watching for a possible reaction after each increase in
temperature.
• Drip a second acid or washing aid slowly into a hot sample while watching for signs
of a vigorous reaction.
• Cool the digested sample before you transfer it, or dilute it slowly with water.
• Never use perchloric acid in a pressure digestion.
