However, by using sizeexclusion chromatography columns, easy and high sensitiveanalysis of additives was achieved without any pretreatmentsteps. The target additives are separated from the polymer andthis allows introducing only the low molecular fraction (whichcontains the additives) into MS.UV(210nm)m/z 1176(Negative)5 6 7 8 9 10 11 12 13 14 15 16min5 6 7 8 9 10 11 12 13 14 15 16minColumn : <strong>Shodex</strong> GPC KF-402HQ x 2Eluent : THFFlow rate : 0.3mL/minDetector : UV(210nm), APCI-MS(SIM)Column temp. : 40˚Cnot detectedIRGANOX ® 1010Columns for Polymer-based Hydrophilic Interaction Chromatography (HILIC) Aqueous/Organic SEC Columns Organic SEC (GPC) Columns[Columns for LC/MS Analysis] Columns for Polymer-based Reversed Phase Chromatography61
