The lower reading range of the results for the purposes of this work: from LOQ of the method

* The recovery for the method was calculated according to the following formula:

Recovery[%]=Cw−CmCd⋅100%
where:

  • Cd - the concentration of the substance added to the sample,

  • Cm - the concentration of the substance in the sample where analyte has not been added,

  • Cw - the concentration of the substance measured in the spiked sample.
