Feature of High Temperature Analysis (3) (Fast Analysis)
ET-RP1 4D is polymer base column for high temperature analysis. Figure shows comparison chromatograms between 40°C and 80°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. Please refer to
Sample : 5μL, 10mg/L each 1. Caffeine 2. Pyridine 3. Phenol 4. Propyl paraben 5. Acetophenone 6. Benzene 7. Toluene (notes) * Eluent was introduced to column after preheating and introduced to detector after cooling. * Preheat eluent when high flow rate (more than 1mL/min) is applied.
