In the process of preparative chromatography separation, fast liquid chromatography columns with high efficiency and stability play an extremely important role in establishing reliable separation and purification technology. A fast column with high separation performance ensures maximum separation of target compounds from impurities. WelFlash cartridge is a new generation of Flash cartridge produced by Welch Materials through rigorous quality measurement. The narrow size distribution of the packing materials ensures that the column pressure is kept low during use. The shell of the column tube is made of polypropylene material, which also ensures compatibility with various solvents. The product has the advantages of high pressure resistance, good column efficiency and corrosion resistance. The performance parameters of each batch of WelFlash cartridges are carefully controlled and rigorously tested to ensure a high recovery rate and good reproducibility from batch to batch.
WelFlash Packing Materials
The packing materials for WelFlash cartridges are divided into three types: amorphous silica matrix, spherical silica matrix and non-silica inorganic adsorbents. Amorphous silica gel packing materials include silica gel and C18, while spherical silica gel has a wide variety of packing materials, including silica gel, C18, phenyl, cyano, amino, ion exchange, Hilic, etc, providing you with a variety of sample selection. lnorganic adsorbents packing materials include acidic, neutral and alkaline alumina packing materials. The fast chromatographic column packing materials consisted of particles ranging from 20 to 75μm, and the particle size distribution was optimized. All WelFlash cartridges packing materials undergo rigorous quality testing, and parameters such as particle size distrilbution and pore size ar carefully screened to ensure reproducibility from batch to batch.
WelFlash Cartridge Specifications
The easiest way to shorten separation time is to use short column and high flow rate. But since short columnlength leads to decreased column efficiency, we recommend column length between 10-75 mm, which is the best proportion after optimization to ensure largest sample loading and best separation efficiency.
WelFlash cartridges are available in the following specifications: 4g, 12g, 25g, 40g, 80g, 120g, 220g, 330g, 800g and 1600g.
WelFlash Cartridge Compatibility
- Luer-lok import and Luer export, good compatibility with most systems, such as lsco, Biotage, and Armen.
- PP column tube and adapter can tolerate the pressure of regular systems.
