However, our SECcolumns can separate the additives from the polymer and introduce only the low-molecular-weight fractioncontaining the additives into MS, thus enabling easy and highly sensitive analysis without any pretreatment step.UV(210nm)Sample : Cup of instant noodles (styrene foam) 1000mg/L, 5μLm/z=1176(Negative)IRGANOX 1010Column : Shodex GPC KF-606M x 2Eluent : 10mM LiBr in DMFFlow rate : 0.5mL/minDetector : RI(small cell volume)Column temp. : 40˚CReducing the analysis time to less than half of that for the standardcolumn (KF-802.5) requires KF-602.5 which enables high-speed analysis.On the other hand, KF-402.5HQ has a number of theoretical plates 1.5times larger than that of the standard column, thereby improvingresolution especially in the analysis of molecules that have a small tomedium molecular weight. Both columns spend solvent amounting toonly about one third of the quantity spent by the standard column and areeco-friendly.Column : Shodex GPC KF-802.5 x 2Shodex GPC KF-402.5HQ x 2Shodex GPC KF-602.5 x 2Eluent : THFFlow rate : (KF-802.5) 1.0mL/min(KF-402.5HQ) 0.3mL/min(KF-602.5) 0.6mL/minDetector : (KF-802.5) RI(conventional type)(KF-402.5HQ, KF-602.5) RI(small cell volume)Column temp. : 40˚CPhthalatesSample : 10μL1.
