Description

Description générale

Retention Mechanism: Normal-phase or adsorption
Sample Matrix Compatibility: Organic solutions

• Dual layer glass SPE tube that contains Na₂SO₄ (upper layer) and Florisil (magnesium silicate; lower layer) separated and packed with PTFE frits
• Florisil particle size- 60/100 mesh (150-200μm); 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
• Suitable for the determination of the hydrocarbon oil index in water (surface, waste, and sewage treatment plants) by GC-FID analysis according to European Standard EN ISO 9377-2 : 2000
• Glass SPE hardware allows user 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
