| Definitionskos:definition | Also known as SRM, these samples may range from International Standards and Certified Reference Materials (CRMs) to locally prepared standard samples for use as project reference standards. They are comprised of homogenous material prepared under strict guidelines, divided into numerous aliquots and sent to reputable laboratories to derive an assigned value. The values for Standard Reference Materials are generally well known published figures. SRMs with certified values are used to calibrate instruments or analytical techniques, to quantify analytical accuracy, and to verify new or improved analytical techniques. The material of the reference standard (eg, rock, mineral, water, etc) should be denoted in "material type". |
