L. Broudiscou et Y. Papon, QUANTIFICATION OF AMMONIA IN RUMEN AND FE RMENTER FLUID SAMPLES BY A GAS-SENSING ELECTRODE, Reproduction, nutrition, development, 34(3), 1994, pp. 193-200
The use of an electrode for the determination of ammonia in rumen and
fermenter fluid samples has been evaluated The amount of interfering v
olatile bases was negligible in our samples. The memory effect was onl
y significant at the limits of the ammonia concentration range. The re
sults from the electrode method were linearly correlated with the valu
es from the standard colorimetric method (slope = 1.009; R = 0.998).
