Alumina
DAI’s alumina for chromatography
(alumina, Dynamic Adsorbents' Aluminas - Analytical, Prep LC, Sample
Processing, Specialty Aluminas, Alumina Deactivation Protocols) has
contributed to the continued growing use of this material in a diverse
number of applications. Indeed, the major reason for this growth has
been our contribution to the standardization of the manufacturing
process. This has resulted in standardized grades of alumina that are
very well controlled and defined.
Alumina, by being amphoteric (acting
either as a base or an acid as well as being configured as neutral)
provides the chromatographer the ability to separate a multitude of
compounds over and above silica gels. Alumina can act as a weak ion
exchanger demonstrating anionic or cationic properties, while
additionally acting as an adsorbent.
Dynamic Adsorbents aluminas are unique
products; e.g., Super I, Std Act I, etc: High activity alumina can be
used for polar samples in nonpolar solvents, and for the purification of
solvents. Lower activities of alumina can readily be obtained by the
addition of polar media, especially water. Thus, each problem can be
resolved via the adjustment of the sorption system, as required for each
problem.
Super activity I aluminas are unique as
DAI's products; they demonstrate approximately twice the capacity as
compared to Standard activity l; Surface modifications available are "A"
(Acid), "B" (Basic), and "N" (Neutral). Super activity I aluminas
constitute the starting material for the Dynamic Adsorbents line of
aluminas. Therefore, it is easy to change between various modes of
chromatography. A special feature of Super activity I is absolutely
constant deactivation behavior which is valid for the deactivation
process as well as when in contact with the chromatographic solvent.
DAI produces a number of specialty
aluminas, (product details) including the following:
- Alumina C for PCB removal
- Alumina P for pyrogen removal
- Alumina R used for purifying,
separating, and product formulations in the radioactive field
- Alumina for solvent purification
- Alumina for pilot and process
- DrysphereTM (product details)

Silica Gel
Dynamic Adsorbents, Inc. silica gels
(product details) are carefully manufactured and quality assured to
provide the ideal laboratory and pilot process chromatographic material.
We control the manufacturing process from raw material to finished
product. We carefully control the physical characteristics of pore size,
surface area, particle size and surface chemistry to ensure reproducible
optimized chromatographic behavior for uniform capacity, reproducible
selectivity, improved resolution and excellent performance.
Only Dynamic Adsorbents provides a
detailed analysis to the customer with each lot of silica gel material,
assuring the customer of the quality of the received product.
Nylon Foil Tubing
This tube is used to hold silica gel
during the dry column chromatography process and is sold
folded and in rolls. It is easy to remove possible creases by blowing a
hot air stream through the tubing. Shaking the tubing in acetone prior
to the hot air treatment facilities “ironing” of the nylon tubing
Polyamide
Polyamide is based on
Nylon 6. Due to its activation process it exhibits a constant
selectivity toward flavones, chalkones, anthraquinones, aromatic nitro
compounds, DNP amino acids, phenols, carbonic acids, acid amides,
sulphonic acids and amides of sulphonic acids as well as towards amines
and quinones. Forces which contribute to the separation involve hydrogen
bonding between the nitro groups, the phenolic protons, the carboxyl
groups etc. of the sample and the free amino groups of the adsorbent.
Florisil PR
Florisil PR is a new
selective adsorbent, specially processed to give consistent results when
used for column cleanup and separation of chlorinated pesticide residue
prior to identification and measurement of the pesticide by gas, thin
layer or paper chromatography. This material is packed in Alumina
Bottles to ensure purity during storage, shipment and usage.
