HayeSep® Porous polymers
from Hayes Separations, Inc.
NEW!
ValcoPLOT capillary columns
with HayeSep polymers
HayeSep porous polymers are thoroughly cleaned and preconditioned for twelve
hours under oxygen-free nitrogen before packaging. Our handling techniques
produce polymers which are consistently the same, with no shrinkage and minimum bleed.
Columns packed with HayeSep require minimum conditioning.

HayeSep A
|
|
|
Separates permanent gases (hydrogen, nitrogen, oxygen,
argon, carbon monoxide, and nitric oxide) at ambient
temperatures. Also exhibits good separation
characteristics for the C2's, hydrogen sulphide, and
water at higher temperatures.
|
HayeSep B
|
|
|
Separates C1 and C2 amines as well as trace levels of
ammonia and water. Eliminates the need for caustic washing
of material prior to packing.
|
HayeSep C
|
|
|
Separates polar hydrocarbons such as hydrogen cyanide, ammonia, hydrogen sulphide, and water.
Separation characteristics are similar to Chromosorb® 104.
|
HayeSep D
|
|
|
High purity divinylbenzene, unavailable anywhere else.
Superior separation characteristics for light gases,
including the separation of CO and CO2 from room air at
ambient temperatures and the separation of acetylene
prior to other C2's. Particularly useful in the
separation and analysis of water and hydrogen sulphide.
Available in four formulations.
|
HayeSep N, P, Q, R, S, and T
|
|
|
These polymers are interchangeable with the Porapak®
series for separations of low molecular weight materials
containing halogens, sulphurs, water, alcohols, glycols,
free fatty acids, esters, ketones, and aldehydes.
