WebSep 8, 2024 · A Spiking Solution is a standard that is chosen for preparing a matrix spike; the concentration of the analyte in the spiking solution is usually 50 -100 times higher than the concentration found in the unspiked sample. This simplifies the calculations and avoids introducing unknown effects from dilution of the matrix.

WebBoth the spiked and diluted unspiked samples are assayed. Percent total recovery is determined by dividing the total HCP measured (from endogenous and spike) by the sum of the spike level + the endogenous contribution of HCP. We suggest acceptable recovery should be within 80% to 120% of the spiked HCP. WebWhat is the Energy Concentration?
