Moisture analysis

What are some good instrumental analysis methods for analyzing the water content in p-toluidine? Our company uses the KF method with automatic instruments for analysis, but the results are highly inconsistent: a small sample size yields low results, while a larger sample size gives higher results. Why does this phenomenon occur? I need expert advice! ! ! :o
The KF automatic instrument has strict requirements regarding the sample volume to be injected; please select an appropriate injection volume in accordance with the specified range for moisture content in the instrument’s operating procedures
