Karat and fineness
Determine gold content in jewellery, bullion and scrap without destroying the piece.

Precious metals
Assay, refining and hallmarking leave no room for a wide error bar. These are the instruments we specify for gold, silver and platinum-group work.
Where the decimal place is the margin
In precious-metals work the analytical result is the commercial result. A fineness figure decides what a bar is worth; a trace impurity decides whether a refining batch passes. The instrument has to be right, and it has to stay right between calibrations.
We help refiners, assay offices, jewellery manufacturers and recyclers across India match the technique to the decision being made — non-destructive screening where the piece must survive, dissolution and ICP where the last decimal place matters.
Trace impurities in refined metal
Quantify deleterious elements in high-purity gold and silver down to trace levels.
SPECTRO ARCOS →Incoming material verification
Screen consignments on arrival before they enter the refining process.
SPECTRO xSORT →Platinum-group elements
Separate and quantify PGE content in catalyst material and refining streams.
SPECTROGREEN MS →Not sure which technique fits?
Send us a description of your samples and the elements and ranges you need to report. We will come back with a recommendation, and where useful, run your material on a demonstration instrument.
