Comprehensive Chemical and Elemental Composition Analysis of Shilajit

Looking for an analytical laboratory to perform a comprehensive chemical and elemental composition analysis of Shilajit (Asphaltum punjabianum) supplied as a dry powder. The primary objective is to quantify humic acid content and identify the percentage composition of additional organic and inorganic constituents. The analysis should include both chemical profiling and elemental characterization. Our company is based in the UK; however, samples may be shipped to qualified laboratories in the US or internationally.
