Diverse Application and Application Field of Empty Flash Column

Customized Column for Different Purification

Hawach empty flash column is machined-packed with pure silica gel, which allows the user to add needed samples according to different applications. It has a narrow particle size distribution, and tightly controlled water content, and wide surface area. Innovative column design provides convenience and flexibility with leaking-free performance.

Solid load or direct liquid injection provides users with the desired reproducible result. The customized column meets the diverse needs of users for different purifications in the application. Standard Luer connection is easy to available flash systems and adapts to most of the organic samples.

Work Principle of Empty Flash Column

The work principle of a flash column involves chromatographic separation. Initially, a sample is loaded onto a column filled with a stationary phase (e.g., silica gel). A mobile phase (eluent) is introduced, carrying the sample through the column. Compounds in the sample interact differently with the stationary phase, leading to separation based on affinities. The eluting fractions are collected, representing distinct components. The separation is monitored and optimized through adjustments in parameters. Flash chromatography enables rapid and preparative-scale separation of chemical compounds for analytical or purification purposes.

Hawach flash column is packed with a solid stationary phase and the mobile phase is passed through it by some external pressure. The separated samples are monitored by the operator after passing through a flash column and collecting the remaining fraction. As the flash column becomes more popular in normal-phase separation, it is often used to separate and isolate different samples from a compound or mixture. There are many varied applications of the empty flash column such as used as a solid load cartridge. High flow rates and excellent column pressure are guaranteed by innovative design and high-quality materials.

Wide Application and Excellent Purification

Hawach is available in different varieties and types of flash columns, and each of them provides its own features. The empty flash column has a new design in wide application, and customers can add needed sorbet according to specific purifications and then reduce additional costs in equipment purchase.

Just like other flash columns, an empty flash column is equipped with standard Luer-lock end fittings, which are convenient for solid load and relative liquid injection. Additionally, excellent column pressure can withstand 200 psi operating pressure. Medical PP cartridge tubes can greatly enhance the flexibility, safety, and compatibility of the purification process.

Cleaning of Empty Flash Column

The choice of solvent is perhaps the most difficult in the whole-column chromatographic separation operation and the most critical to the success of the experiment. Solvents are usually screened by simple silica gel TLC. In most cases, cleaning the flash column is a complicated procedure, you have to pour out the remaining solvent, but this process is troublesome and extremely easy to cause environmental pollution.

By using the vacuum pump, the remaining solvent is decompressed, and a pumping device is installed between the flash column and the vacuum pump, which can effectively clean the remaining solvent in the flash column without polluting the environment.
