    Immunoassay interference caused by reagents (additives, excipients) incorporated in the blood sampling systems is undetectable by the conventional methods for intralaboratory quality control, by using reference substances. A large number of manufacturers and a great physicochemical variety of additives in the current vacuum and non-vacuum systems require that additional measures be made to monitor systemic errors in immunochemical studies. The review considers the mechanisms of this type of interference and the problems of its monitoring and prevention.

    Atomic Absorption Spectroscopy: Interference

    Interference leads to systematic error in atomic absorption (AA) measurements by enhancing or diminishing the analytical signal or the background. These interferences can be grouped into three main categories: spectral interference, chemical interference, and physical interference.
    Spectral interference occurs when signals from other elements or molecules overlap with the analyte signal, falsely elevating or masking the analyte's absorbance. This interference can be corrected using Zeeman,...

    Inductively Coupled Plasma-Mass Spectrometry (ICP-MS): Interferences

    Inductively coupled plasma–mass spectrometry (ICP–MS) is a highly selective and sensitive technique for accurate elemental analysis. Though the analysis of ICP–MS mass spectra is comparatively straightforward, it is affected by spectroscopic and non-spectroscopic interferences. Spectroscopic interferences arise when the plasma contains ionic species with an m/z value the same as the analyte ion. Spectroscopic interference can be categorized as isobaric, polyatomic ions, and refractory oxide ion...
