mobile phase and therefore backpressure提高温度可以降低流动相粘度及其反压 Higher linear velocities are achievable with reduced backpressure and therefore faster analysis times随着反压的降低，可以实现更高的线速度，因而分析时间可以更短 Selectivity can vary with Temperature allowing temperature to bemanipulated to achieve better separations选择性随温度变化，使得温度可以成为实现更好分离的选择性调节手段 Using post column cooling drastically reduces the UV detector noise seen when a hot mobile phase cools in the flow cell使用柱后冷却功能可以使热流动相在检测池中冷却，显著降低紫外检测器的噪音 LC/MS sensitivity can be increased by using elevated temperatures into the MSLC/MS灵敏度可以因液相色谱使用较高的温度而提高Page
