I conducted an assessment studies on wastewater for the presence of pharmaceuticals and all values after working back to original sample of 1L were below the limit of quantification of the method of analysis used
How should the data be reported in a manuscript?
Ps: I used SPE in concentrating the 1L to 2ml for the HPLC reading and afterwards the obtained values were converted to back to the concentration in 1L
Thanks in advance for your answers
If you are publishing the results, the journal you are submitting to probably has a standard format for tables etc.
Otherwise, if it is a report or thesis, "
Mrs/Miss Ekhosuehi,
Looking at your objects of analysis a reliable determination at the instrumental limit of detection can be carried out only by mass spectrometry; furthermore, only by means of our own-authored (to me and my co-author's innovation according to the authorship shown in the references) innovative stochastic dynamic theory and model formulas.
Thus, if you operate at these concentration ranges, then you could publish the results as we have carried out our quantification in reference [1] mentioned in discussion [A] (below), citing work [1] itself.
[A] [https://www.researchgate.net/post/Lipidomics_with_a_very_low_detection_What_to_do]
Please, keep in mind that our method (reference [1] in [A]) is the only available, currently, worldwide method for exact quantification.
The application of any other method is higly disputable and the corresponding results are very doubtful from the perspective of reliability in chemometric terms.
Generally speaking, as the LOQ allude to the limits related to 95% probability of getting a conventional result,
You can report as BQL(Below Quantification Limit) and specify the Linearity, Range, LOD(Limit of detection) and LOQ(Limit of quantification) in separate table.
