The Microchemistry Laboratory

Low cost methods of chemical analysis appears to be very useful for the study of alchemy experiments. Of course some scientists may argue that it exists today better tools of analytical chemistry to study complex mixtures, but, in my opinion, when doing chemical analysis one must consider the efficiency of the method and its cost. In the present case, it appears that microchemical technics are more efficient that very expensive methods of analysis because using appropriate methods of separation we may concentrate the interesting elements in order to get a very precise identification.
The Microchemistry Laboratory is divided in three sections :

- The Analytical section
- The chemicals section
- The mineralogy section
All sections are complementary : in order to reduce costs, most of the reagents are prepared, when necessary, from cheap materials. Five balances have been bought since 1991 : Three Mettler balances ( two with s = 0,1mg , one with s = 1 mg) , an old balance Prolabo s = 0,1mg , an electronic balance s = 1mg, and a set of calibration weights.
Other part of the Lab. is a mini lathe which has been used to make several ring-oven apparatus.
A very good base of chemistry data regarding microchemistry , organic and inorganic syntheses has been obtained after several years ; some are indicated below. (not includind e-books which represent several hundred of Go) :
