Carboxen GC PLOT Capillary Columns
Supelco PLOT Columns
Supelco PLOT columns are an ideal choice for many permanent gases
and light hydrocarbon analyses in the petrochemical industry.
Supelco PLOT columns are prepared using a proprietary patented
adhesive technology that firmly bonds the adsorbent particles to the
wall of the capillary column. The adhesive also bonds the particles to
each other, eliminating particle loss during routine analysis or rapid
temperature programming. A significant feature of the adhesive is its
high temperature limit, greater than 360 °C, which makes the
operating temperature of the column a function of the particles
used, not the adhesive.
Supelco PLOT columns are individually tested for efficiency, inert-
ness, and retention. Each column is shipped with a chromatogram
demonstrating column performance that can be expected.
Carboxen Capillary PLOT Columns
Carboxen™ PLOT columns are the appropriate choice for permanent
gas mixtures that include permanent gases and C1 to C3 hydrocar-
bons. Carboxen PLOT column chemistry is based on synthetic,
spherical carbon molecular sieves that are synthesized in-house
under carefully controlled conditions. Each Carboxen has a unique
combination of pore size, pore structure, and surface area. These two
features permit analyte separations not possible with other PLOT
columns.
Carboxen-1010
A larger pore structure (7 Å ) and increased number of pores make
Carboxen-1010 PLOT columns the preferred choice over zeolite Mol
Sieve 5A PLOT columns for effectively separating oxygen, nitrogen,
and larger analytes up to C3. Because the Carboxen surface is
hydrophobic, samples containing water do not cause retention time
shifts, eliminating the need for thermal conditioning as necessary
with Mol Sieve 5A PLOT columns.
Carboxen-1006
Carboxen-1006 has a multiporous pore structure. The presence of
large macropores and mesopores allow for effective access of the
7 Å micropores for fast kinetic applications. This unique pore
structure makes Carboxen 1006 suitable for permanent gases and
light hydrocarbons. The inert surface chemistry makes it an excellent
choice for formalin analyses.
