Methyl Alcohol, Purge and Trap, is the perfect solvent to use in the purge-and-trap procedure for determination of volatile organic compounds (VOCs). The procedure involves purging a sample with an inert gas, such as nitrogen or helium at ambient temperature (water) or slightly elevated temperatures (soil). This liberates the VOCs, which are efficiently transferred from the aqueous (or solid) phase to the vapor phase. During this purge step, the inert gas is swept to an analytical trap containing a solvent sorbent which retains the VOCs. The trap is then desorbed and the VOCs are transferred to the GC for analysis.
