Description
Retention Mechanism: Normal-phase or adsorption. Sample Matrix Compatibility: Organic solutions. Dual layer SPE tube that contains Na2SO4 (upper layer) and Florisil (magnesium silicate; lower layer) separated and packed with PTFE frits (glass tubes) or PE frits (PP tubes). Florisil particle size - 60/100 mesh (150-200 μm); Na2SO4 Purity- 99.99+%, density- 2.68 g/mL. Excellent for removing/isolating polar compounds from organic matrices. Na2SO4 layer aids in removing aqueous sample residues that may hinder Florisil performance and/or subsequent GC analysis. Available in glass SPE hardware allowing users to reactivate Florisil through heating at 140°C, 16 hours . Use in conjunction with Visiprep Large Volume Sampler (Cat No. 57275) and Visiprep SPE Vacuum Manifolds for processing larger volume samples.Specifications
