PACKED/MICROPACKED COLUMNS
Packed Columns Overview
Put the power of Restek® packed columns to work for you.
• SilcoSmooth® tubing provides the inertness of glass and the durability of stainless steel, so you get accurate results for a wide range
of active compounds.
• Stable bonded stationary phases mean short conditioning times, low bleed, and long column lifetimes.
• Excellent retention time reproducibility delivers reliable, consistent results.
Packed columns offer large sample capacity and often can retain and separate compounds that cannot be analyzed by other tech-
niques. While these advantages have resulted in their use in a wide range of GC applications, traditional packed columns are limited
by unstable phases that break down easily, producing high column bleed and short column lifetimes. In addition, the tubing used
for packed columns can present challenges; columns packed in glass tubing are inflexible and break easily, whereas columns made
with metal tubing typically are not inert, meaning active compounds cannot be analyzed accurately as they react with metal tubing.
Restek® packed columns overcome these problems and are preferred over conventional packed columns, because they are excep-
tionally rugged and inert. You can generate accurate data quickly and reliably with less downtime for column changes with Restek®
packed columns since they combine high-quality SilcoSmooth® tubing with stable bonded phase technology. SilcoSmooth® tubing
is rugged, ultra-smooth seamless 304 stainless steel tubing that is deactivated with an innovative Siltek® treatment. This process
results in packed columns that have both the inertness of glass and the strength and flexibility of stainless steel. In addition, our
bonded phase technology features a coated support that is extremely stable and results in longer column lifetimes, lower bleed, and
excellent reproducibility.
