Description

Porapak R (100-120 Mesh ASTM) for GC is a high-performance porous polymer bead packing material specifically designed for gas chromatography (GC). Its unique composition provides excellent separation capabilities for a wide range of polar and non-polar compounds, ensuring reliable and reproducible analytical results. This product is essential for analytical laboratories, quality control facilities, and R&D departments in the chemical, petrochemical, pharmaceutical, and environmental monitoring industries.

Application

• Gas Chromatography (GC) Separation: Primary use as a stationary phase packing material in packed GC columns for the analysis of complex mixtures.
• Volatile Organic Compound (VOC) Analysis: Effective for separating and quantifying VOCs in environmental air and water samples.
• Petrochemical Analysis: Used in the separation of light hydrocarbons, fixed gases, and sulfur compounds in refinery process streams and natural gas.
• Pharmaceutical Impurity Profiling: Employed in the separation of residual solvents and volatile impurities in active pharmaceutical ingredients (APIs) and drug products.
• Food and Flavor Analysis: Suitable for the analysis of aroma compounds, alcohols, and esters in food, beverage, and fragrance applications.
• Industrial Hygiene Monitoring: Packed in sampling tubes for the collection and subsequent GC analysis of workplace air contaminants.
