Manufactured from pure cellulose fibers, it is free from contaminants, making it ideal for sensitive applications where precision is critical. The paper?s robust structure prevents tearing during handling, while its compatibility with a wide range of solvents and staining techniques adds to its versatility. Whether used in thin-layer chromatography (TLC) or general filtration tasks, Whatman 31ET maintains integrity under varying conditions, providing researchers with a dependable medium for accurate data collection. Its neutral pH and low ash content further ensure minimal interference with sample composition, preserving the integrity of experimental outcomes. Designed for ease of use, this chromatography paper is available in multiple sizes to suit diverse lab requirements, from small-scale experiments to larger analytical workflows.
FAQs
1. What is the flow rate of Whatman Grade 31ET Chromatography Paper?
Whatman Grade 31ET is classified as a medium flow rate paper, offering balanced capillary action for efficient separation without excessive sample diffusion.
2. Can this paper be used with organic solvents?
Yes, it is compatible with most organic solvents commonly used in chromatography, though pre-testing is recommended for specific applications to ensure optimal performance.
3. How does the thickness of this paper compare to other Whatman grades?
Grade 31ET is slightly thicker than fast-flow grades like 1 Chr but thinner than high-retention grades, providing a balance between flow rate and sample capacity.
4. What storage conditions are recommended to maintain its quality?
Store in a cool, dry environment away from direct sunlight and chemical fumes. Keep the original packaging sealed until use to prevent moisture absorption.
5. Is this paper suitable for quantitative analysis?
While primarily designed for qualitative applications, it can support semi-quantitative work if calibrated properly, though dedicated quantitative grades may offer better precision.
