Notes

Submit as a separate sample (Particulate F- on MCEF, carbonyl fluoride on impregnated backup pad). The filter and filter spacer reside in one section while the impregnated backup pad is in another section of a 3-piece polystyrene cassette.

The filter and backup pad should not have physical contact with one another. When analysis of a compound is requested, an analysis is performed for fluoride (F-) and reported as the compound. Carbonyl fluoride gas is collected on a Na₂CO₃ impregnated backup pad.
