Plasma concentrations of sulindac and its metabolites, sulindac sulfide and sulindac sulfone
, were quantified by ultraperformance liquid chromatography tandem Photodiode Array (UPLC-PDA) .
The combination of features such as mechanically tough and rigid, transparent, resistance against hydrolysis and against acidic attacks and melt processing at temperatures of up to 400[degrees]C, coupled with ease of fabrication, has enabled sulfone
polymers to be used in a wide and increasingly diversified range of applications.
