BIO-42 quantitative papers are designed for retention of extremely small particles. A common example is use of BIO-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  BIO-42 filters also makes them suitable for processes that require ashing.
