Characteristics of Hawach Flash Columns

As a professional lab experiment solution provider, HAWACH is dedicated to making the experiment easier and more accurate by offering different kinds of consumables, which can be integrated with a great variety of optional which increases the performance of the experiment and can fulfill specific requests.

Hawach flash column has three series

HawachFlash series: There are only silica gel flash columns, which are divided into standard and advanced types. Advanced silica gel has higher purity and better quality.

Other Flash series: Corresponding to silica gel phase chromatography columns, C18 (spherical inlet and irregular domestic), C4, C8, NH2, CN, HILIC, alumina, etc. are all imported packings, applied to high-end markets.

DepuFlash series: Corresponding to silica gel phase column, C18 (spherical and irregular), C8, NH2, CN, Phenyl, SAX, SCX, Diol. All are domestically made fillers, corresponding to the low-end market and Empty Chromatography Columns.

Important technical parameters of the Flash column

1. Material: Medical PP column, medical sintered PE sieve plate, imported adsorbent packing
2. Stationary phase parameters: Matrix type (such as silica gel or polymer); Jianhe phase type (such as C18 or CN); particle size (such as 3 um, 5 um);

The specific surface area of the stationary phase (eg 130 m2 / g);
Uniformity (this can emphasize the quality of the adsorbent is OK, but the customer will not propose specific parameters when purchasing), the purity of the stationary phase (this can emphasize the quality is OK, and general customers will not ask for specific parameters when purchasing), the shape of the stationary phase particles (such as: irregular or circular, this point is not high, so customers may not write specific requirements when buying).

Highlights of Hawach flash column

Flash columns are a type of chromatography column designed for rapid and efficient separation of compounds. The characteristics of flash columns can vary depending on the manufacturer and specific product, but here are some common features associated with flash columns:

  1. Column Material:
    • Flash columns are typically made from materials such as glass or plastic, ensuring compatibility with a wide range of solvents commonly used in flash chromatography.
  2. Column Dimensions:
    • Flash columns come in various dimensions, including different lengths and diameters. The choice of column size depends on the scale of the separation and the amount of sample to be processed.
  3. Particle Size and Type:
    • Flash columns contain a stationary phase, usually composed of silica gel or other materials, with a specific particle size. The particle size influences the resolution and speed of the separation.
  4. Column Frits:
    • Flash columns have frits (porous filters) at both ends to support the stationary phase and allow the solvent to pass through while retaining the solid material.
  5. Compatibility with Flash Chromatography Systems:
    • Flash columns are designed to be compatible with flash chromatography systems, which typically involve the use of a pump to elute the sample through the column.
  6. Loading Capacity:
    • Flash columns have a specified loading capacity, indicating the maximum amount of sample that can be loaded onto the column without compromising separation efficiency.
  7. Compatibility with Various Solvents:
    • Flash columns are designed to be compatible with a broad range of solvents commonly used in chromatography, allowing flexibility in method development.
  8. Prepacked or Empty Columns:
    • Flash columns are available in prepacked formats, where the stationary phase is preloaded, or as empty columns, allowing users to pack their desired stationary phase.
  9. Applications:
    • Flash columns are versatile and can be used for a variety of applications, including the separation and purification of organic compounds in synthesis or natural product extraction.
  10. Ease of Use:
    • Flash columns are designed for ease of use, enabling quick and efficient separations. They are often used in laboratories for routine purification tasks.
  11. Compatibility with Detection Methods:
    • Flash columns are compatible with various detection methods, including UV detection, fluorescence detection, or other detectors commonly used in chromatography.
  12. Disposable or Reusable Options:
    • Flash columns may be available as disposable columns for convenience or as reusable columns for multiple applications.
  13. Column Markings:
    • Many flash columns have volume markings on the column body, aiding in the measurement of elution volumes during the chromatographic process.

It’s important to note that specific characteristics may vary among different brands and models of flash columns. Always refer to the manufacturer’s specifications and recommendations for optimal use and performance. Additionally, advancements in chromatography technology may lead to improvements and variations in flash column design over time.
