Interference may appear in an assay as partially or completely co-eluting peaks in the analyte or internal standard mass chromatograms. Interference may also be virtually invisible to technologists—a matrix effect. Labs should be able to mitigate interference by taking advantage of three elements of … Meer weergeven Analytical interference is the effect of a substance, identified or not, that causes the measured concentration of an analyte to differ from its true value (1). Method developers using LC-MS/MS need to consider … Meer weergeven While labs are able to minimize interference, they rarely are successful in eliminating it completely (the ugly part). Consequently, clinical lab professionals absolutely need to assess susceptibility to analytical … Meer weergeven To ensure that any newly developed LC-MS/MS method is robust and provides high-quality data, we strongly advocate investigating interference by performing the experiments outlined in this article during the … Meer weergeven WebMatrix interferences in inductively coupled plasma mass spectrometry (ICP-MS) were examined to extend the total interference level (TIL) concept from ICP-AES. The TIL model is based on measurements with different interferents to determine a set of interference coefficients. Interference is assumed to be linear with interferent concentration, since …
