contamination

In trace analysis, this is the unintentional introduction of analyte(s) or other species which are not present in the original sample and which may cause an error in the determination. It can occur at any stage in the analysis. Quality assurance procedures, such as analyses of blanks or of reference
materials, are used to check for contamination problems.
