1 Interlaboratory comparison NP02
1.1 Participants and time schedule
Number of registrations: 12
Number of submitted data records: 11
Dispatch of samples: 24th February 2015
Closing date for submission of data: 24th March 2015
To anonymise results, each laboratory was given a laboratory code on a random
basis.
1.2 Sampling, sample material and distribution
One wastewater and one surface water were selected as sample material. The
sampling was carried out on 23rd February 2015. The samples were stored at < 4 °C
until further processing. The groundwater was partly spiked with specific substances.
The samples were filled into bottles with continuous stirring. The homogeneous
mixtures were dispatched on 24th February 2015. Each participant received:
2 samples, filled in 1000 ml aluminium bottles.
1.3 Check analysis
While filling the bottles, aliquots of each sample were collected at random moments
for check analysis. Testing was performed 8 days after sample dispatch.
In the parameter-oriented evaluation, the results of the check testing are listed in the
form of arithmetic means of the detected concentrations as check value ± U The
uncertainties of the check value were calculated as extended uncertainties (k=2).

2 Evaluation
The analytical results had to be made available to the organiser not later than 24th March 2015. Any values received at a later date were not considered. A statistical evaluation of interlaboratory comparison data was only carried out if at least 6 valid results per parameter were available.
To evaluate the data, outliers were detected first by using the outlier test method according to Hampel. Values identified as conspicuous by this test method are marked specifically in the parameter-oriented evaluation. Further evaluation was performed in accordance with DIN ISO 5725-2. The adjusted average value (after removal of outliers) for all submitted results was used as a basis for the calculation of recovery rates.
z-Score
z-Scores were calculated on the basis of the following formula:
Xxscorez i
In this context,
ix is the measurement value of the participating laboratory.
X is the adjusted average value (i.e. after removal of outliers) of the participants‘ results.
σ is the reproducibility standard deviation, calculated from the participants‘ results (after removal of outliers) in the relevant test round.
Interpretation of z-Scores in the parameter-oriented evaluation:
|z| < 2: result: good
2 < |z| < 3 result: questionable
|z| > 3 result: not satisfactory
3 Representation and interpretation of measurement results
The parameter-oriented evaluation shows the measurement values including
uncertainty, recovery rate, calculated z-Score and the outliers in tabular form. The
results listed in the table are also illustrated in graphical form (see 5 Explanatory
notes on the parameter oriented report)

Possible remarks in the column comments:
H Outliner according to Hampel-Test
FN False negative – For a result < LOQ (level of quantification): The absolute value of the
LOD/LOQ fulfils the condition of an outliner according to the Hampel test.
FP False positive – For parameters where no target value is available because of a too low
analyte content (n < 6): Result that exceeds the median of the absolute values of the
transmitted LOD/LOQs by more than 100 %.
