I am trying to find an extraction method for my analyte using traditional solvent extraction but I didn't find .Then I waste lots of time developing method till reached the goal .
Ok . Now my question how you can say I searched the litreature but I could't find such things .Someone might ask did you search the whole universe to say that , I feel the question is logic but again to my best ability of search using ( google , web of knoweledge , scholar ) couldn't find such a thing .
Again how I can say confidently (( there is no published material on X while it is so difficult to search all the resources )) as an example look at this List of academic databases and search engines page :
http://en.wikipedia.org/wiki/List_of_ac ... ch_engines
I hope I could find one search engine can search in all of these so we can say surely all litreature published with their numbers .
I will be happy to read comments
