Restek's RT®-XLSulfur column is the second generation of packing material for the analysis of sulfur compounds. The first packing material, in the Rt®-Sulfur column, had intertness characteristics for low ppmv levels of sulfur compounds. Now, with the second generation, our innovative Rt®-XLSulfur column, it is possible to achieve low ppbv detection of sulfur compounds.

 

What is the RT®-XLSulfur column?

Rt®-XLSulfur packed and micropacked columns are designed for the ppb-level sulfur analysis. Every component of the sample pathway is treated to provide the highest degree of inertness for reactive, low-level sulfur compounds. The porous polymer phase features a unique surface modification, which results in excellent peak symmetry and thermal stability to 300°C.

 

What are the benefits to using Restek's RT®-XLSulfur column?

The Rt®XLSulfur column combines a packing material surface deactivation with Sulfinert® tubing and end-fittings to yield unsurpassed inertness and high thermal stability for highlt reactive sulfur compounds. The Rt®-XLSulfur column offers the most reliable, reproducible analyses for low ppc-level sulfur samples.

 

For which applications should I use an Rt®-XLSulfur column?

The high performance and reproducibility of the Rt®-XLSulfur column enables resolution and quantitation of COS, H2S, SO2, CH3SH, (CH3)2S2 at low ppb concentrations. These sulfur compounds typically are found in pulp mill byproducts, natural gas, and petroleum products.
