Rxi-5HT GC Columns

5% Diphenyl, 95% Dimethyl Polysiloxane

Engineered for demanding high-temperature GC applications, the Rxi-5HT combines the selectivity of a 5% diphenyl phase with the durability of specially processed fused silica tubing. Its optimized construction provides exceptional thermal stability, low bleed, and long-term reproducibility, making it an excellent choice for laboratories routinely analyzing high-boiling or thermally demanding samples.

Specially processed fused silica tubing delivers approximately 40% longer column lifetime compared to conventional fused silica columns.
Optimized for high-temperature GC applications where thermal stability, reliability, and long service life are essential.
Low stationary phase bleed supports cleaner baselines and improved detector performance during elevated temperature analyses.
Maintains excellent chromatographic performance throughout aggressive temperature programs, helping preserve reproducibility over extended use.
Particularly well suited for high-boiling compounds, including mineral oil and other thermally demanding applications.
Equivalent to USP G27 and G36 phases.
