Frequently Asked Questions
1. What is the difference between ashless and qualitative filter paper?
Ashless (quantitative) filter papers are washed with acid to remove impurities, leaving an ash content of less than 0.01%. They are used for precise gravimetric analysis. Qualitative papers are used for general clarification where the weight of the residue is not critical.
2. How do pH-Fix strips differ from standard litmus paper?
pH-Fix strips feature dye molecules that are chemically bonded to the cellulose fiber. This prevents the dye from "bleeding" into the sample, protecting the sample from contamination and ensuring a clear, accurate color comparison even in weakly buffered solutions.
3. Are CHROMAFIL® syringe filters compatible with all solvents?
Macherey-Nagel offers CHROMAFIL® filters in various materials. For aqueous solutions, PES or RC membranes are ideal, while PTFE or Nylon membranes are recommended for aggressive organic solvents used in HPLC and GC.
4. Can QUANTOFIX® test strips be used for professional water quality reporting?
QUANTOFIX® strips are designed for rapid semi-quantitative screening. While highly accurate for quick checks, they are typically used as a pre-test or for routine monitoring. For official regulatory reporting, MN photometers and liquid reagents are often preferred.
