Rt-XLSulfur Columns (Packed and Micropacked)

Rt-XLSulfur packed and micropacked columns are designed for 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.

The high performance and reproducibility of the Rt-XLSulfur column enables resolution and quantitation of COS, H S, SO , CH SH,
2 3
(CH ) S at low ppb concentrations. These sulfur compounds typically are found in pulp mill byproducts, natural gas, and petroleum
3 2 2
products.
Features:
Optimized columns for low pbbv sulfur analyses.

Eliminate the need for PTFE tubing.
Column and end-fittings are Sulfinert® treated for maximum inertness.

Figure 1 The Rt-XLSulfur column analyzes 50 ppb levels of sulfur compounds, providing low bleed and good symmetry.
