Le présent document spécifie une méthode de détermination de l'activité des enzymes déshydrogénases dans le sol à l'aide de chlorure de 2,3,5-triphényltétrazolium (CTT).

Le présent document spécifie une méthode de détermination de l'activité des déshydrogénases dans le sol à l'aide de chlorure de 2-(4-iodophényl)-3-(4-nitrophényl)-5-phényltétrazolium (INT).[1]-[5] Comme la réduction de l'INT est moins sensible à la présence d'O2, cette méthode est plus robuste que la méthode au CTT décrite dans l'ISO 23753‑1.

1.1 General This document is the base standard for a number of other standards dealing with water treatment equipment, water, dialysis water, concentrates, and dialysis fluid (ISO 23500 series) and provides dialysis practitioners with guidance on the preparation of dialysis fluid for haemodialysis and related therapies and substitution fluid for use in online therapies, such as…
