Data Evaluation. This section discusses the methods and techniques used in evaluating the data used to determine effectiveness of the remedial system.
Data Evaluation. For the evaluation of the gaseous emissions, the chart reading of the last 30 seconds of each mode must be averaged, and the average concentrations (conc) of HC, CO and NOx during each mode must be determined from the average chart readings and the corresponding calibration data. A different type of recording can be used if it ensures an equivalent data acquisition. For the NOx check within the control area, the above requirements apply for NOx, only. The exhaust gas flow GEXHW or the diluted exhaust gas flow GTOTW, if used optionally, must be determined in accordance with annex 4, appendix 4, paragraph 2.3.

Data Evaluation. This section discusses the methods and techniques that are used in evaluating the effectiveness of the remedial system. Section 2.5 of the RAWP provides additional details regarding goals of the Northeast Plume monitoring program, the monitoring approach (i.e., hydraulic monitoring, chemical monitoring), and identification of MWs and PZs that will be included in each monitoring approach (DOE 2018a).
Data Evaluation. For the evaluation the equations for the double IDMS approach. To calculate the isotope ratios in bx and bz, the peak areas in the according chromatograms of the various isotopes are integrated using a proper software recommended by the manufacturer of the ICP-MS and the ratio is calculated according to: 𝑅bx = 𝐴yx 𝐴x ; 𝑅bz = 𝐴yz ; 𝐴z Rbx, Rbz, isotope ratio in the blends bx and bz, resp. Ayx, Ayz peak area of the spike isotope (m/z = 65) in the blends Ax, Az, peak area of the reference isotope (m/z = 63) in the blends Double IDMS is used because in this case the reference serves as a kind of back spike to characterise the isotopically enriched spike material and, therefore, it is not necessary to know the exact mass fraction of the protein in the spike. The concentration of SOD1 in the sample is calculated according to: 𝑚yx 𝑚z 𝑅y − 𝑅bx 𝑅bz − 𝑅z 𝑤x = 𝑤z ∗ 𝑚x ∗ 𝑚yz ∗ 𝑅bx − 𝑅x ∗ 𝑅y − 𝑅bz wx mass fraction of SOD1 in sample x wz mass fraction of SOD1 in reference z mz mass of reference z in the blend bz myz mass of spike y in the blend bz mx mass of sample x in the blend bx myx mass of spike y in the blend bx Rz isotope ratio of SOD1 in reference z Rbz isotope ratio of SOD1 in blend bz Rx isotope ratio of SOD1 in sample x Rbx isotope ratio of SOD1 in blend bx Ry isotope ratio of SOD1 in spike y To calculate the mass fraction of SOD1 in reference wz, the purity of the protein used as reference has to be determined using various methods such as amino acid analysis, ESI-MS as well as total metal quantification and post-column IDMS. For the isotope ratios Rx and Rz the isotope abundances listed in the IUPAC table can be used as the natural variation of Cu is too small to be detected by quadrupole ICP-MS. Ry has to be measured beforehand. A full uncertainty budget for wx has to be estimated according to the Guide of the Expression of Uncertainty in Measurement (GUM).
