Chromatography papers are available in different grades to meet specific requirements for aspiration speed, thickness, sample loading and separation performance.
Available Grades:
- Grade CH01 – Fine, Medium Aspiration: Suitable for general chromatography, detection of malic acid in wine, and high school and university practical work.
- Grade CH02 – Fine, Medium Aspiration: Designed for general chromatography and determination of components by elution.
- Grade CH03 – Medium, Medium Aspiration: Suitable for separation of organic compounds, electrophoresis, chromatography with high solute loading, and separation/identification of food additives.
- Grade CH17 – Thick, Medium Aspiration: Suitable for electrophoresis involving high molecular weight compounds and protein analysis in serums.
- Grade CH20 – Very Thick, Quick Aspiration: Designed for electrophoresis involving high molecular weight compounds.
Primary Applications: Chromatography, electrophoresis, analytical separation, sample identification, and laboratory testing.
