What is the difference between granded oven dried fish samples and ashed fish samples in processing fish samples for chemical analysis?
Mr. Bwala,
It is important to detail which MS methods you use to heavy metal analysis, because of if you use soft ionization MS methods, then the corresponding heavy metal ions stabilize different inorganic and metal-organic complexes in both the condensed phases. Furthermore, there can be observed a ligand exchange of inorganic ligands in solution. In such cases, there should be carried out a parallel speciation of solid-state samples and those in solution.
I would like to mention that currently exact speciation and quantification of analytes in both aforementioned condensed phases can be carried out only by our own-authored (mine and my co-author's according to the shown authorship) innovative stochastic dynamic mass spectrometric method and corresponding formulas. The method has been tested at analyte concentrations of pg-(mL)-1 and ng.(L)-1 levels, showing a linear correlation between theory and experiment /r/ = 0.99997-1.
Please, consider the following references dealing with application of our method to analysis of different phases and type of analytes.

@Bojidarka Ivanova,
Thanks for your answer.
Your response has helped greatly.
Thanks
from ashed samples you would not expect to get any reasonable data from GC-MS analysis as all compounds You can analyse by GC-MS would be burned or volatised.
