Matrixeffect

2023年3月16日 — The process involves adding a series of small increments of the analyte to the sample and measuring the signal. The assumption is that the ...

由 P Panuwet 著作 · 2016 · 被引用 330 次 — In HPLC coupled with either MS or MS/MS, the most commonly observed matrix effect is ion suppression, a loss of ion intensity of the target analyte.

The use of immunoassays for the quantification of analytes in biological samples such as, plasma, serum, tissue homogenates, etc. can be challenging.

The matrix effect is the effect on an analytical assay caused by all other sample components except the specific compound (analyte) to be analyzed.

The matrix can have a considerable effect on the way the analysis is conducted and the quality of the results are obtained; such effects are called matrix ...

基质常常对分析物的分析过程有显著的干扰，并影响分析结果的准确性。例如，溶液的离子强度会对分析物活度系数有影响，这些影响和干扰被称为基质效应（matrix effect）。

由 陳家揚 著作 · 2007 · 被引用 4 次 — Matrix components in the extract may influence the ionization efficiency of an analyte, and in most cases, suppress the formation of ions. This will deteriorate ...
