Preferred Label : matrix effect;
IUPAC definition : surface analysis effects which cause changes in auger-electron, photoelectron, secondary
ion yield, or scattered ion intensity, the energy or shape of the signal of an element
in any environment as compared to these quantities in a pure element. (a) chemical
matrix effects: changes in the chemical composition of the solid which affect the
signals as described above. (b) physical matrix effects: topographical and/or crystalline
properties which affect the signal as described above.; analytical chemistry the combined effect of all components of the sample other than
the analyte on the measurement of the quantity. if a specific component can be identified
as causing an effect then this is referred to as interference.;
