Catalog Number - 59050-15P

MicroBee Amino™ is a traditional aminopropyl HPLC stationary phase developed for laboratories requiring a proven alternative to legacy amino column methods. As part of the Cogent™ Similars product line, it has been widely used for many years in carbohydrate analysis, normal phase chromatography, and other applications where amino selectivity is desired. The stationary phase consists of a bonded amino functional group attached to high-purity Type-A silica, providing retention characteristics comparable to traditional amino columns used in established methods.

59050-15P is a 150 mm x 4.6 mm ID analytical column packed with 10 µm, 125Å MicroBee Amino particles. The 150 mm length offers a practical balance between resolution and run time, making it suitable for routine analytical testing and method transfer applications. The industry-standard 4.6 mm ID format typically operates optimally at approximately 1.0–2.0 mL/min on conventional HPLC systems.

This column is an excellent alternative for methods specifying USP L8 columns, including methods developed on Microbondapak™ Amino and similar stationary phases. Supplied in normal phase solvents, it is optimized for normal phase chromatography and related separations. The aminopropyl functionality provides selectivity useful for carbohydrate analysis, geometric isomer separations, and other applications where traditional amino phases are preferred.
