Matrix spike sample definition

Matrix spike sample means a sample prepared by adding a known quantity of the target analyte to a field sample matrix or to a matrix that is as closely representative of the matrix under analysis as possible.

Matrix spike sample means a sample prepared by adding a known quantity of each of the target analyte to a sample matrix or to a matrix that is as closely representative of the matrix being analyzed as possible. The spiked concentration must be at a mid-range concentration of the calibration curve for the target analytes.

Matrix spike sample means second portion of actual sample used to prepare the MS that is spiked and processed in the same manner as the MS. The MS and MSD are used together to measure the precision of methodology. means a sample prepared by adding a known quantity of each of the target analyte to a sample matrix or to a matrix that is as closely representative of the matrix being analyzed as possible.
