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.
The formation of a flash phenomenon
The boiling point of water is higher than 100℃ when the water is heated under a certain pressure. The higher pressure, the water has higher the boiling point, and the higher the caloric content. When the pressure reduces, some sensible heat is released, and this needless heat will be absorbed in the form of hidden heat, causing some water to “flash” into steam.
The differences between the SPE column, Flash column, HPLC column
In general, both the SPE column and the Flash column are used in the pre-processing of the sample being analyzed. After the pre-processing is completed, the sample is then sampled. The HPLC column was used to separate glucose, maltose, and sucrose from sugars in an HPLC (High-Performance Liquid Chromatograph) instrument.
It should be noted here that the properties of the salt and the sugar are very different, so they are well separated. However, the properties of glucose, maltose, and sucrose in sugars are very similar, and it is difficult to separate them. Therefore, the separation capacity of the HPLC column is much larger than that of the SPE column and Flash column.
Highlights of Hawach flash column
HAWACH flash column is packed with proprietary technology for automatic packing. The column bed is compact and uniform, has no “ditch flow effect”, with high resolution and good reproducibility.
Different particle sizes of normal phase and reversed-phase silica packing allow users to freely choose different fast separation columns in terms of resolution, sample loading, and flow rate according to different needs of cost and performance.
HAWACH flash column is made of medical-grade polypropylene (PP) material, which avoids the dissolution pollution of common PP materials on the separation sample. In addition, the transparent PP material cylinder can also allow users to visually observe the separation of samples. The column design makes the high-pressure column of the flash column up to 300psi which is safe and leak-free. All HAWACH flash columns have Luer-Lock standard fittings and can be used on a variety of fast liquid chromatography separation systems.
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).
