The 18 components of C1-C5 hydrocarbons were well separated on a single, packed column operated ated around 40t within 20 mm. The chromatographic column is 25% sebaconitrile / chromosorb PAW (lOrn x O3cm, 60-80 mesh). The optimum flow rate was determined by making a simple Van Deemter plot of the number of theoretical plates VS. linear gas velocity. The most efficient flow-rate of N2 carrier gas was at 35mg / mm, and the mumber of theoretical plates was 5,000-10,000. The linearity of calibration curves were checked ranging ppm to % concentration of CR4 and C:1 11$. Peak through C5 hydrocarbons, and relative standard deviations of 10 measures were less than 2.1%.
고성능 액체크로마토그래피를 이용한 DNP-아미노산의 역상 이온쌍크로마토그래피적 분리

Some derivatized DNP-Amino acids can be separated by a reversed-phase ion pair chromatography, in which several quarternary ammonium ions are added to the mobile phase in a reversed phase column. The retention behavior of DNP-amino acids can be controlled by the separation conditions of the ion pair chromatography. The separation selectivity is enhanced by increase in the chain length of the alkyl group of quarternary ammonium ions. On the other hand, the separation efficiency decreases with the chain length of the groups.

The 18 components of C_1-C_5 hydrocarbons were well separated on a single, packed column operated around 40℃ within 20 min. The chromatographic column is 25% sebaconitrile/chromosorb P-AW(10m x 0.3㎝, 60-80 mesh). The optimum flow rate was determined by making a simple Van Deemter plot of the number of theoretical plates VS. Iinear gas velocity. The most efficient flow-rate of N_2 carrier gas was at 35㎖/min, and the mumber of theoretical plates was 5,000-10,000. The linearity of calibration curves were checked ranging ppm to % concentration of CH_4 and C_3 H_8. Peak area was used for quantitating the C_1 hydrocarbon through C_5 hydrocarbons, and relative standard deviations of 10 measures were less than 2.1%.
