  • Statistical Corrections Microbial Monitoring in Grade C/D Cleanrooms

    Microbiologists rely on the Feller table to correct for undercounting of biological activity. The “Table of statistical corrections according to Feller” is based on the principle that as the number of viable particles — colony forming units (CFUs) — impact on an agar plate increases, the probability that viable particles will enter unoccupied space decreases. This table is ...
