BI-200SM Research Goniometer - MALS

  • Particle Size Analyzers

  • DLS/SLS

  • MALS

  • Molecular Weight Analyzers

 

규격

  • 측정모드:

    • 정적광산란(Static Light Scattering)

    • 동적광산란(Dynamic Light Scattering)

  • 산란각도:

    • 8° ~ 155° with 25 mm cells

    • 15°~ 155° with 12 mm cells

  • 각도조절 : 0.01°

 

  • 필터 횔:

    • 632.8 nm (HeNe)

    • 514.5/488.0 nm (Ar+)

    • 532 nm band-pass filter

    • Open Position

    • 2 X Shutter

 

특징

  • Laser Light Scattering 원리를 이용하여Sub-Micron대의 입도(particle size) 분포(distribution) 및 분자량을 분석 하는데 사용되는장비입니다.

  • 일반 입도분석기나 laser power가 고정된 입도분석기로 Nano입자를 측정하기 위해서는 어느 정도 농도가 있어야 하지만 이 장비는 아주 저 농도의 ample도 측정가능한 장비입니다.
