GEMINI, COLUMBUS speakers PHENOMENEX C18, C6-Phenyl, etc.

GEMINI speakers. The mechanically robust reverse-phase sorbent of the columns provides an extended service life under extreme pH conditions and excellent stability and reproducibility during separation with high efficiency. The sorbent of GEMINI columns is a combination of the best qualities of silica gel and polymers. The high degree of inoculation and the chemical inertia of the GEMINI sorbent make it ideal to use this product for preparative HPLC. A wide operating pH interval ensures a long period of operation of the column during the preparative purification of the main compounds using a high pH value. In addition, the highly developed surface of the sorbent makes it possible to dramatically increase the load on the column in preparative chromatography both in the case of low and high values of the hydrogen index.

Types: C18, C6-Phenyl.

• GEMINI speakers. Characteristics (eng).

Columbus speakers are designed to provide reliable and reproducible separation for traditional HPLC methods. The dense coating of the ends ensures the stability of the Columbus columns, since the silica surface is protected from unwanted silanol activity.
