Demonstrated equivalency of SPC method & DNPH/acetonitrile impinger method. Refers in materials list to SPC Silica , but actually uses C18 cartridge. Incorrectly quotes manufacturer (Waters) as identifying body & filter material as polypropylene (actually crosslinked polyethylene). Some batches of C18 packing were shown to contain traces of formaldehyde.
