Super I Activity |
Super activity I aluminas are
unique to Dynamic Adsorbents. They demonstrate
approximately twice the capacity when compared to
Standard activity l. Available surface modifications
consist of "A" (Acid), "B" (Basic), and
"N" (Neutral). Super I aluminas show an
approximate double capacity as compared to Activity
I. Super I does not have to be deactivated in steps.
By following the appropriate deactivation curves,
deactivation can be achieved in minute increments.
Deactivation behavior by the following procedures
makes it relatively easy to obtain the desired
activity.
Use high activity alumina (standard activity I, super activity l)
for the separation of polar samples in nonpolar
solvent systems and for the purification of
solvents. Use lower activity alumina for less polar
samples.
Deactivation Behavior
By following the procedures below, it is relatively
easy to obtain the desired activity.
Deactivation Behavior - Alumina
Activity Grade
Alumina Type Super I I II III IV V
Super I - A,B,N 0 1 4 7 10 19% Water Added
Std Act I - A,B,N 0 3 6 10 15% Water Added
A = Acid, B = Basic, N = Neutral
Deactivation Procedure(s)
The % water addition shown above are based upon
weight / weight relationships; these relationships
are critical and any deviation may result in
obtaining improper activity.
To reproducively obtain the desired activity, weigh
an appropriate amount of alumina into a stoppered
glass bottle. Add the appropriate weight of water to
the alumina and close the bottle. For example, 97 g
of alumina + 3 g H20 = 3% water addition.
Shake well until all lumps disappear. Wait until the
mixture has cooled to room temperature. Keep the
container closed so that equilibrium conditions
remain constant |
|
Standard Activity I
|
Alumina standard activity I is
available with various surface modifications to
facilitate the separation of a wide range of
compounds. In addition to pH, the activity on the
surface of alumina can mediate the separation.
|
|
Activity II, III Alumina
|
Economical adsorbents of medium
activity. Use this material for general purpose
scouting and for cases where the use of
carbon black is precluded due to its organic nature.
Also, use alumina II - III as a replacement for
organic/polymeric ion exchangers, especially when it
is necessary to overcome problems associated with
temperature and radiation cleavage. |
|
Dry Column Chromatography (DCC) Alumina
|
A versatile Prep
LC method bridging the gap between analytical
TLC and preparative column chromatography. (Request DCC Application Guide).
|
|
‘Flash” Alumina
|
Flash Chromatography is a rapid prep LC technique
that facilitates the separation of 0.1 - 10 g of
material via simple economical laboratory protocols.
