Krypton Low-Surface-Area Analyzer for Thin Films and Flat Substrates

薄膜与平整基底用氪气低比表面积分析仪

Coatings, wafers, ceramic pellets and low-area crystals have too little surface for nitrogen BET. Using krypton at 77 K with 1 and 10 torr transducers, this analyzer measures down to 0.05 m² total area and 0.001–20 m²/g. Repeatability is within 4% RSD at 0.1 m². Choose 1 or 2 analysis ports depending on throughput.

Product Description 产品描述

Coatings, wafers, ceramic pellets and low-area crystals have too little surface for nitrogen BET. Using krypton at 77 K with 1 and 10 torr transducers, this analyzer measures down to 0.05 m² total area and 0.001–20 m²/g. Repeatability is within 4% RSD at 0.1 m². Choose 1 or 2 analysis ports depending on throughput.

Highlights

  • Krypton adsorption for very low surface areas
  • Handles samples with only 0.05 m² of total area
  • Transducer accuracy ±0.15% of reading
  • One or two analysis ports

Applications

  • Thin film and coating surface area
  • Nuclear fuel pellet and ceramic analysis
  • Flat wafer and substrate characterization
  • Low-area pharmaceutical crystals
