- The purpose of this work was to survey the effect of the third and fourth central moment from the chromatographic elution curves of two peptides according to different particle sizes (5, 15 μm), pore sizes (100, 300 A) and flow rates (0.5, 0.75, 1.0, 1.25, 1.5 mL/min). Also, the skewness and excess, as well as the asymmetry factor were determined according to particle and pore sizes.
대상 데이터
- In this experiment, the HPLC was performed using a Waters 600S solvent delivery system (Waters, Milford, MA, USA). A 2487 UV dual channel detector (Waters, Milford, MA, USA) was used. The data acquisition system was a Millenium52 (Waters) system installed in a HP Vectra 500 PC.
- The molecular weights of the two peptides, anigotensin II (C50H71N13O12 xH2O) and bradykinin (C50H73N15O11) were 1, 046 and 1, 240, respectively. The HPLC grade solvent, acetonitrile, was from Ducksan Pure Chemical (Kyungki-Do, Korea). Trifluoroacetic acid (TFA) was purchased from Sigma (St.
- A 2487 UV dual channel detector (Waters, Milford, MA, USA) was used. The data acquisition system was a Millenium52 (Waters) system installed in a HP Vectra 500 PC. The water was filtered by an ultra-pure water system (Milipore, Bedford, MA, USA).

이론/모형
- The chromatographic peaks were analyzed by the method of moments [5-8]. In general, in order to completely characterize an arbitrary probability distribution function, all moments are required.
