MPN (Most Probable Number)

Kumpulan Tabel MPN

Berikut beberapa tabel MPN untuk berbagai seri tabung yang dihimpun dari berbagai sumber metode baku.

Tabel 1. Berbagai kategori hasil nilai MPN pada tabel MPN 3 seri tabung beserta pengelompokan kategori kombinasi tabung dengan inokulum 1 g (mL), 0,1 g (mL) dan 0,01 g (mL), dengan derajat kepercayaan 95 %.
