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 2 S, SO 2 , CH 3 SH, (CH 3 ) 2 S 2 at low ppb concentrations. These sulfur compounds typically are found in pulp mill byproducts, natural gas, and petroleum 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.
