Alumina(A/B/N)Alumina solid phase extraction column/SPE column

Alumina is a typical lewis acid, The aluminum atom center lacks two electrons. It has  strongly polar adsorbent, similar to that of silicone, There are three high activity levels of acidity, alkalinity and neutrality; Alumina also has a special effect on theπelectrons of aromatic hydrocarbons, It is better than silicone in high pH conditions. The main retention mechanisms are lewis acid/base action, polarity and ion exchange.

Acid alumina The lewis acid properties of alumina-A (pH=4.5) were enhanced, This kind of adsorbent has better retention for the rich electron compounds. In addition, when pretreatment with acidic solution, the adsorbent has weak cationic properties, the surface is more likely to retain neutral and negatively charged substances (such as  electroneutral  or acidic anions), Can’t keep a positive charge.The weak ion exchange property also makes it easier to retain the negative charge material.

Basic alumina The surface of the Alumina-B(pH=10) is favored to retain either positive or hydrogen – bonded materials. Aluminum oxide treated with alkaline solution has anionic properties and cationic exchange function. In addition, although the surface has the characteristics of lewis base, it can be retained for the electron sample, such as neutral amine compounds. The ability is much lower for neutral and acidic alumina. In addition, strong hydrogen bond can be found on the alumina-b, so the effect of the polar cationic sample is also obvious.

Neutral alumina Alumina-N(pH=7.5) is also a strongly polar adsorbent. Under the condition of high pH, alumina is more stable than that of the unbonded functional group. Finer particles ensure good extraction efficiency, so a small size cylindrical bed (50mg) is the most commonly used product. The adsorbent is electrically neutral and tends to retain rich electronic compounds such as aromatic and fatty amines. At the same time, there is also the ability to retain compounds containing electronegative groups such as oxygen-containing, phosphorous and sulfur atoms. Alumina-N can be used for extraction and separation of polar or non-polar substances in water-soluble and non-aqueous samples.
