Before use poly(2,6-diphenylphenylene oxide) should be thermally conditioned with a high purity gas at elevated temperatures to remove any residual components.

Therefore, control of blanks is essential and storage time of samples on poly(2,6-diphenylphenylene oxide) is less than a month.

Although the polymer has a low affinity for water, high humidity in air may lower the breakthrough volumes of substances.

Volatile substances in liquid or solid matrices can be made available by the purge and trap technique.

The polymer is of particularly used for concentration of high boiling compounds such as alcohols, polyethylene glycols, diols, phenols, monoamines and diamines, ethanolamines, amides, aldehydes, ketones and chlorinated aromatics.
