Small molecules are ions and compounds of molecular weight typically less than 900 daltons. These compounds can be effectively separated and analyzed by HPLC, UHPLC and LC-MS using mainly silica particles or monolithic stationary phases with a broad range of column chemistries (modifications).
小分子特指低分子量化合物（通常小于900道尔顿），分离小分子方法包括高效液相色谱(HPLC)、液相(LC)、气相(GC)、薄层色谱(TLC) 和毛细管电泳(CE)。此外，还可通过磁共振波谱法(NMR)或 质谱法(MS)等方法鉴定小分子。
