Method blank definition
Method blank means an analyte-free matrix to which all reagents are added in the same volumes or proportions as are used in sample preparation.
Method blank means a sample of a matrix devoid of or having a consistent concentration or amount of the analytes of interest processed simultaneously with and under the same condi- tions, preparatory and analyses steps as the associated samples.
Method blank means an analyte free matrix to which all reagents are added in the same volumes or proportions as used in the sample preparation and is processed in exactly the same manner as the samples.
Examples of Method blank in a sentence

Method blank means a clean matrix containing only the internal standard. The method blank is used to assess background interference or contamination that exists in the analytical system that might lead to the reporting of elevated concentration levels or false positive data. Results from tests of the method blank should be below the limit of quantitation.
