Agilent Polaris Si-A HPLC columns have a non-bonded silica stationary phase designed for normal phase (non-aqueous) applications. Based on 180 Å silica with high surface area, the Polaris Si-A columns provide excellent peak shape and retention for polar samples. Manufactured with fully porous particles in 3 µm, 5 µm, and 10 µm sizes for use with HPLC instruments.
Features
- Polaris Si-A chemistry is designed for separation in normal phase mode
- Ultra-pure silica provides superior peak shape and retention with highly polar samples
- Meets USP L3 classification
- Fully porous columns available with 3 µm, 5 µm, and 10 µm particle sizes
