Feature of High Temperature Analysis (3) (Fast Analysis)

ET-RP1 4D is polymer base column for high temperature analysis. Figure shows comparison chromatograms between 40deg-C and 80deg-C. Mobile phase viscosity decreased at high temperature analysis, higher flow rate can be applied. And suitable flow rate range is shifted to higher at high temperature. ET-RP1 4D is good column for fast analysis with high temperature analysis.
