Linearity was in the range of 159-513 ng/zone for (1), 99-238 ng/zone for (2), 97-244 ng/zone for (3), 69-163 ng/zone for (4), 63-170 ng/zone for (5), 103-250 ng/zone for (6), 84-251 ng/zone for (7) and 94-260 ng/zone for (8). LOD and LOQ were 53 and 159 ng/zone for (1), 32 and 98 ng/zone for (2), 32 and 97 ng/zone for (3), 23 and 69 ng/zone for (4), 21 and 63 ng/zone for (5), 34 and 103 ng/zone for (6), 28 and 84 ng/zone for (7) and 31 and 94 ng/zone for (8), respectively. Selection of appropriate viscosity of the mobile phase may be important in obtaining optimal chromatographic separation.
