Biosolids / Sewage Sludge PT Standards

Phenova Biosolids


Biosolids are falling under more environmental regulation both internationally and domestically. The Phenova Whole-Volume Biosolids Studies allow your laboratory to work with the same sample type that you see daily. The analyte lists include anions, trace metals, and quantitative microbiological components. Our matrix preparation ensures that each standard is homogenous, both in terms of the matrix and the fortified analytes, so you aren’t left to wonder if it is a true biosolids sample.
