Dynamic Adsorbents’ Alumina
Judged Best in Industry
News Release
Dynamic Adsorbents’ activated alumina and silica gel products
have been found by independent laboratory analysis
to be demonstrably superior due to a lower amount of
fines compared with major competitors and with the
least amount of trace metal impurities compared with
all other competitor’s products.
When announcing the results, DAI President Dr.
Mark Moskovitz said, “Our line of adsorbents
offer precisely what chromatographers have come
to expect from all DAI products – the best
alumina, the best silica and the best bonded
phase packing material available for academic or
industrial usage.”
A recent study by an independent research laboratory
found that DAI’s neutral and basic Alumina products
were the industry leaders in their categories,
surpassing competitors by almost every measure in
consistency, purity and performance.
Dr. Moskovitz elaborated further,
“What’s important in these test results is that
it shows that our Alumina has the greatest
surface area per gram of adsorbent and has the
lowest trace metal impurities in the industry.
All chromatographers are looking to achieve high
purity fractions and, to obtain these kind of
results, you need superior resolution in your
alumina or silica. Using the best materials
leads to higher compound recovery, saving
significant costs and time as fewer fractions
require purity analysis. Results depend on the
quality of the adsorbents and DAI makes the best
alumina and silica in the industry. We are very
proud of these results.”
DAI
bulk and DynaFLASHTM
cartridge alumina are manufactured to achieve high
resolution separations with injections of complex
mixtures.
-
DAI provides the
widest range of alumina and
silica products for the widest range of
uses.
-
DAI has the ability to customize
products
for unique applications and with 24 hour
delivery in most cases.
-
DAI’s alumina can be purchased in bulk
quantities or in the DynaFLASHTM
family of pre-packaged, disposable cartridges.
-
DynaFLASHTM
cartridges provide tight particle and pore size
distribution and a low level of fines. Each
cartridge is a pre-compressed, disposable flash
column containing either superior premium
grade alumina or premium grade silica.
-
DynaFLASH™ Cartridges are compatible with the Isco, Jones, or Biotage Flash Systems.
