SFC Chromatography Column, 250x4.6mm 5µm, 155291-GS-PYE4 (CAT#: STEM-C-2693-ZJF)

Many SFC separations use "older normal-phase HPLC-type" stationary phases (such as unmodified silica, diol, amino, and cyano). These stationary phases are often unsuitable for SFC, presenting several limitations, including low capacity, poor selectivity, and suboptimal peak shapes.
In contrast, our GreenSep™ stationary phases are specifically designed for SFC separations, with a keen focus on bonding coverage, density, and other factors that contribute to high-capacity stationary phases. GreenSep phases offer excellent selectivity and peak shape. Many GreenSep phases designed for basic and acidic compounds do not require mobile phase additives, whereas other brands often need mobile phase buffer salts. The GreenSep product line features a wide range of selectivities that complement each other, providing comprehensive solutions for various separations.
These phases are available in analytical, semi-preparative (10 mm), and preparative (20 mm, 30 mm, and 50 mm internal diameter) specifications, ensuring flexibility and scalability for diverse applications.

Stationary Phase: 4-Ethyl Pyridine II
Specification: 250x4.6mm 5µm

Specifically designed for high-performance SFC separations, offering better separation, selectivity, peak shape, and injection capacity compared to traditional normal phase HPLC fillers suitable for SFC.
High-efficiency chromatographic columns with excellent reproducibility produced through our stringent bonding procedures.
Enables direct scaling from analysis to preparative on the same medium, simplifying purification steps and maximizing operational efficiency.
Many stationary phases are chemically tailored, eliminating the need for mobile phase buffering salts (such as triethylamine).
