Continuous quantitative analysis of low concentrations of tributyl phosphate (TBP) vapors in flowing air streams.

A quantitative analytical technique is described for measuring low concentrations of airborne tributyl phosphate (TBP) vapors. This technique used a modified Meloy PA460 continuous phosphorus gas analyzer. Concentrations of TBP as low as 0.12 mg/m3 were detected. A procedure for calibration of this instrument using TBP vapor is also detailed.
