WebUse the link in Reference 35 to obtain a copy of EPA Method 8315A. Outline the procedure necessary to quantify carbonyl compounds (other than formaldehyde) in aqueous samples. Next, determine how the MDL values for hexanal and decanal isolated from solid samples differs from that for liquid samples. Fluorescence Detection (FD). WebWhile gas chromatography (GC) methods have been developed for detecting these compounds, the HPLC-UV method is the most commonly used technique for the analysis of carbonyl-DNPH derivatives. U.S. EPA has published several methods for the determination of carbonyls in ambient air (EPA TO-11), ambient indoor air (EPA 8315A mmd モーション 配布 なつき
