PFA Microcolumn 15ml Geochemical Laboratory Ware Low Blank Value

Description

This PFA (Perfluoroalkoxy) Microcolumn is a high-performance chromatography vessel specifically designed for ultra-trace metal analysis and isotope geochemistry. Its 15ml capacity and superior material purity make it essential for labs requiring “low blank” values and high chemical resistance.

Technical Specifications

• Material: High-purity PFA (Perfluoroalkoxy) resin.

• Volume Capacity: 15ml.

• Thermal Range: Stable from -200°C to +260°C.

• Chemical Stability: Universal resistance to strong acids (HF,HCl,HNO3​,H2​SO4​) and organic solvents.

• Surface Property: Hydrophobic and ultra-smooth to prevent sample “hang-up” or memory effects.

Key Features

• Ultra-Low Blank Values: Manufactured in clean-room environments to ensure minimal background contamination, crucial for ppb/ppt level detection.

• Translucent Design: Allows for clear visual monitoring of resin beds and liquid levels during elution.

• Tapered Geometry: Optimized for precise flow control and efficient separation of geological samples.

• Durability: Unlike traditional glass or cheaper plastics, PFA is virtually unbreakable and resistant to environmental stress cracking.

Geochemical Applications

• Isotope Separation: Ideal for Sr, Nd, Pb, and Hf column chromatography.

• Trace Element Analysis: Used in ICP-MS sample preparation to avoid leaching from vessel walls.

• Acid Digestion: Safe for use with concentrated Hydrofluoric acid (HF) which would dissolve standard quartz or glass ware.

Cleaning & Maintenance

• Pre-Cleaning: Recommended to soak in reagent-grade HNO3​ (nitric acid) before first use to ensure a “blank-free” starting point.

• Reusability: Fully autoclavable and easy to clean due to the non-stick nature of the fluoropolymer surface.
