Method 5038

Triphenyl phosphate by GC/FPD

This method is for the determination of triphenyl phosphate. The sample is collected on 37-mm cellulose ester membrane filters (0.8-µm pore size) with cellulose backup pads and extracted with 10mL anhydrous ether. The sample is then analyzed by Gas chromatography equipped with a flame photometric detector and phosphorus filter. The working range is 0.3 to 20 mg/m³ for a 100-L air sample. This method may be adapted to other phosphates of relatively low volatility with appropriate changes in chromatographic conditions. A non-polar capillary column may be used for better resolution and sensitivity. Note: This method revises S210.
