Question
Is it better to centrifuge or filter the sample in the Volatile Acids method 8196?
Summary
Volatile Acids.
Answer
The volatile acids method is very susceptible to loss of volatile acids through evaporation so the quicker the sample is prepped and the quicker the sample is run, the better the analysis. Because of that, the centrifugation will be faster than filtering and there would be less chance (time) for evaporation (loss) of the analyte. The sample should not be suction filtered because it would suck the volatile acids right out of the sample.
