Orochem Technologies has been producing columns for HPLC and UHPLC, flash, chiral and preparative chromatography and related accessories for over 20 years. The Reliasil line of high-efficiency HPLC columns is suitable for general use and is available in a wide variety of phases. The Orosil columns, on the other hand, are particularly suitable for difficult separations involving polar and semipolar compounds. The Orosil C18 column in particular is used worldwide for the analysis of azacitidine (specified in a USP method). Orochem's "Gazelle" brand comprises the UHPLC column series, while the "Epitomize" series summarizes the range of chiral columns. You may use the filters on the left to find the right Orochem column for your application. Feel free to contact us, if you have any questions.
