When finding volatile liquids in open containers, what is the recommended method for collecting them?

The recommended method for collecting volatile liquids found in open containers is to pour a small amount into a clean glass vial with an airtight seal. This method is effective because it minimizes the exposure of the liquid to air, which helps to prevent evaporation and loss of the sample. The airtight seal ensures that the volatile compounds remain contained, preserving their integrity for later analysis. Using a clean glass vial is also crucial since contaminants from other materials could alter the chemical composition of the liquid, potentially compromising the evidence.

This method adheres to best practices in evidence collection, specifically for forensic purposes, ensuring that the sample can be effectively analyzed and used as evidence in investigations or court proceedings.
