The Function And Installation Of Neutral Alumina

Advantages of HAWACH Flash Column
1.Impurity dissolution rate: the materials are all medical-grade PP and PE, which have strong corrosion resistance and low impurity content. There is low probability of impurity dissolution.
2.Diversity of options: a large number of series/types, imported/domestic adsorbents. The features of diverse specifications is convenient for price-sensitive customers and quality-sensitive customers. Customers in different fields can have multiple choice.
3.Particle size distribution curve of adsorbent silica gel: for the parameters of adsorbent particle size of 3um and 5um, it does not mean that the diameter of all particles is this value, but a range. The result obtained by testing this range is the particle size distribution curve.
4.Report of silica gel partial adsorbent purity test; stability test report for StarFlash standard silica flash column.

Function of Neutral Alumina Flash Columns
Hawach neutral alumina flash columns can be used to extract aromatic amines, highly active porous alumina, whose surface electrons can form pi-pi interactions with aromatic rings with strong polarity retention and acid properties. Compared with unbonded silica gel, neutral alumina flash columns is more stable in a high pH environment and suitable for the extraction of aromatic amines.

Installation of Neutral Alumina Flash Columns
Hawach offers some guidance in properly installation of neutral alumina flash column. The first is to wash the column clean to prevent the adsorption of the pipe wall, if the use of dry loading column can wait for the post after drying the direct loading column, so that the filler precipitation is uniform, to elute, so that the column bed to maintain balance, and then can be sampled. If the column is wet, first use the eluent saturated filler, and then press the black button to press the neutral alumina column down. The whole process should be very slow, the sample drop by drop into the column, too fast adsorption, desorption effect is not ideal.
