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 ...

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

SIMS is a method for detecting ions (secondary ions) emitted from a solid surface by sputtering while continuously bombarding that surface with an energetic ...

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