An Overview Of HAWACH SPE Columns
The SPE column consists of a medical PP empty tube, medical PE sieve plate, fixed adsorbent (also called stationary phase), in which the adsorbent is imported raw material.
The quality of SPE columns provided by HAWACH is stable and reliable, suitable for different volume sample processing, and SPE columns can also be customized according to customer needs. With COA, it is the first direct proof of product quality.
The SPE column has strong corrosion resistance, low impurity content, high recovery rate, moderate flow rate, large adsorption capacity, good reproducibility, high-cost performance, and higher repeatability and consistency than similar products. It has excellent results in the extraction of environmental water pollutants, life sciences, food residues, and animal residues, and animal and plant extraction, etc.
The packings are usually chromatographic adsorbents and can be divided into three major categories: silica gel (eg C18, C8, etc.); high polymers, such as polystyrene – two Ethylene benzene, etc.; inorganic materials, such as Floris diatomaceous earth, alumina, graphitized carbon, and the like.
The capacity must be considered when selecting an SPE column. In solid-phase extraction, the adsorbent adsorbs the target compound and adsorbs impurities of the same nature. Therefore, the target compound plus the total amount of impurities that can be adsorbed cannot exceed the column capacity when choosing the column capacity. Otherwise, some of the target compounds may not be adsorbed during the loading process, resulting in a low recovery rate.
