Whatman quantitative papers come in a variety of particle retentions. Also, see hardened ashless grades for work with strong acids or bases.
Ashless paper for gravimetric and instrumental analysis
Whatman Grade 42 quantitative papers from GE Healthcares Life Sciences business are designed for retention of extremely small particles. A common example is the use of Grade 42 as a calcium carbonate filter for analysis in the cement industry.
Other typical precipitates for gravimetric analysis include barium sulfate and metastannic acid for use in glazes, coatings, and pigments. The high purity of GEs Grade 42 filters also makes them suitable for processes that require ashing.
Looking for a filter paper, membrane filter, or syringe filter? Let GE help you find the optimal filter for your needs to ensure reliable analysis.
