There are a number of ways to assay material. At GBA, we understand that our customers have a variety of needs, and that is why we offer both the XRF and fire assay.

Our preferred method of settlement with customers is fire assay, as it is the most accurate. We do know, however, that not everyone has the time that fire assay requires, so the XRF is a great alternative.

We provide third-party assay services, so feel free to contact us for more information.
