packed columns new header

Packed columns offer large sample capacity and can often require and separate compouns that cannot easily be analyzed by other techniques. 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 ccolumn bleed and short column lifetmes. In addition, the tubing used for packed columns can present challenges; column packed in glass tubing are inflexible and break easily, whereas columns made with untreated metal tubing typically are not intert, meaning active compounds cannot be analyzed accurately as they react with the metal tubing.

Restek® packed columns overcome these problems and are preferred over conventional packed columns because they are exceptionally rugged and inert. You can generate accurate data quickly and reliably with less downtie for column changes with Restek® packed columns since they combine high quality SilcoSmooth® tubing with stable bonses-phase technology. SilcoSmooth® tubing is rugged, ultra-smooth seamless 304 stainless steel tubing that is deactivated with innovative Siltek® treatment. This process results in packed columns that have both the inertness of deactiviated glass and the strength and flexibility of stainless steel. In addition, our bonded-phase technology features coated supports that are extremely stable and result in longer column lifetimes, lower bleed and excellent reproducibility.

Put the power of Restek® packed columns to work in your lab tday. Restek offer a broad range of common phases, as well as application-specific products developed for light hydrocarbon analysis, sulfurs, permanent gases and ASTM Method D3606.
