The mass determined by the internal standard method. Offset = determined mass – spiked mass. Recovery yields calculated using the C30d62 ISRC. The ratio of recovery yield of the substance to the recovery yield of the internal standard (BaPd2 for the PAHs and C24d50 for the rest of the compounds). Not applicable.
