General description

Application: This popular column is designed for general purpose applications where a non-polar column is required. The low phenyl content provides thermal stability compared to 100% poly(dimethyl siloxane) columns.
USP Code: This column meets USP G27 and G36 requirements.
Phase:
  • Bonded
  • Poly(5% diphenyl/95% dimethyl siloxane)
Temp. Limits:
  • ≤0.32 mm I.D., <2 μm: -60 °C to 325 °C (isothermal) or 350 °C (programmed)
  • ≤0.32 mm I.D., ≥2 μm: -60 °C to 300 °C (isothermal or programmed)
  • ≥0.53 mm I.D., <2 μm: -60 °C to 300 °C (isothermal) or 320 °C (programmed)
  • ≥0.53 mm I.D., ≥2 μm: -60 °C to 260 °C (isothermal) or 280 °C (programmed)

Application

<ul>
<li><strong>Understanding the core-shell interactions in macrocapsules of organic phase change materials and polysaccharide shell: </strong>Investigates the thermal properties and structural integrity of phase change materials encapsulated in polysaccharide shells, utilizing barium chloride dihydrate for stability testing in energy storage applications (Reddy VJ et al., 2022).</li>
<li><strong>Synthesis of a novel monofilament bioabsorbable suture for biomedical applications: </strong>Focuses on the development of a bioabsorbable suture material enhanced with barium chloride dihydrate, which improves the mechanical properties and usability in surgical procedures, contributing to the advancement of medical materials (de la Harpe KM et al., 2022).</li>
