The retentions of 11 explosives on two commercially RP‐18 and Si 100 stationary phases and one prepared 3‐[9′‐(10′‐methylanthryl)]‐ propylsilane stationary phase (MAPS‐phase) were examined by modified mobile phases. The evaluation of these three stationary phases results as follows: (1) Most explosives were effectively separated on a column of MAPS‐phase not only with methanol/water (75/25‐85/15) as mobile phase but also with n‐hexane/dichloromethane (75/25) as mobile phase. (2) Few explosives were effectively separated on a column of RP‐18 with methanol/water (75/25‐85/15) as mobile phase. (3) The separation of most explosives on Si 100 was achieved only under normal phase condition such as n‐hexane/dichloromethane (75/25) as mobile phase.
