22、esses that occur or may occur. This is also true for the interpretation of GC-MS analysis. As stated, a component is identified if 3 identification points are obtained. If only 1 or 2 diagnostic ions are present, additional identification points are necessary. In this International Standard, gatheri
23、ng additional identification points using analytical procedures is part of Step 2. Using information about the sample, and interpretation of this information, takes place in Step 3. An extra identification point is obtained if one or more of the following criteria is fulfilled. NOTE Strictly taken,
24、an identification point obtained in Step 3 is of another order than the identification points obtained in Step 1 and Step 2. They are obtained by interpretation of additional non-analytical information. In this International Standard, the term “identification point“ (3.7) is used for the points obta
25、ined in all three steps. Step 2: Gathering identification points using analytical procedures. No other ions are visible in full scan mode and this is in agreement with the mass spectrum of the pure component (for instance, PAH). Identification is in agreement with the chromatographic pattern normall
26、y present or present on that site (for instance, PCB or PAH). For volatile compounds, the specificity of the mass fragments in combination with their retention time will generally be sufficient. Their volatility corresponds to a low molecular mass, limiting the number of possible false positive resu
27、lts: there are no low molecular mass compounds with the same retention time on a GC column and also having similar mass spectra. Step 3: Gathering additional identification points using knowledge and interpretation of this knowledge about the sample or sampling site. If identification points are obt
28、ained using Step 3, this shall be reported. The component is identified in earlier samples from the same site (for instance, if the sample under investigation has a low concentration and one or two diagnostic ions have S/N 3 bOnly allowed if the missing ion has the smallest intensity and S/N 3) 1 id

31、n the sample if: Step 1 The criteria given in 6.3.1 Step 1 are met. Step 2 and Step 3 Only one or two identification points are obtained. At least one must be based on the GC-MS data. 6.3.3 Absence of the target compound ( detection limit) The target compound is absent in the sample (not identified
32、and no indication for its presence), if: Step 1 The criteria given in 6.3.1 Step 1 are not met. Step 2 The criteria given in 6.3.1 Step 1 are met and no identification points are obtained with MS, providing the proper GC-MS conditions have been used. 7 Test report The test report in addition to the
