Commission CRM’s

Make CRM’s for your mine

  • AMIS is an ISO 9001:2008 certified matrix matched Certified Reference Material producer.
  • CRM’s are used as control samples.
  • Control samples are needed for every type of sample sent to the lab.
  • Control samples should be as close as possible to the matrix and grade of the samples you are testing. This gives the assayer a fair test, will reduce the frequency of reject batches and will save you money.
  • CRM’s will check assay bias as well as precision and are the best assay control samples.
  • If CRM’s are not available for your specific grades and ores, have them made. It doesn’t cost much.
  • Fill out the request and we will send you a detailed proposal.
