Please send all samples prepared for analysis (fine homogeneous powder); otherwise a preparation charge of 75$/hour will be applied.  All prices are in Canadian dollars.  

Please be aware that some samples require special preparatory work or repeat analyses, for which there may be an extra charge.  Please contact us to discuss the details of what is required for your project.
