Answer:The column measures 60 m × 0.32 mm internal diameter with a 1.00 µm film.
Answer:SPB-1 uses bonded poly(dimethylsiloxane), a nonpolar GC stationary phase.
Answer:For many analytes, retention is dominated by volatility and nonpolar interactions, with separation often tracking differences in boiling point.
Supelco SPB-1 is a nonpolar capillary GC column with a bonded poly(dimethylsiloxane) stationary phase. This configuration measures 60 m × 0.32 mm inner diameter and contains a 1.00 µm film. The long column bed can help resolve complex mixtures that need greater chromatographic separation length, while the thicker film increases retention of more volatile compounds compared with very thin-film alternatives. Nonpolar SPB-1 chemistry primarily separates many organic analytes by volatility, making it relevant to general-purpose GC methods and selected USP stationary-phase requirements. The phase is suitable for methods that specify comparable poly(dimethylsiloxane) selectivity, but any method transfer should account for its exact length, bore, film thickness and temperature limits. The product is a complete capillary column, not loose stationary-phase material.
