Calibration

Certified calibration gases, liquids and solids to assure instrument and analytical method performance.

Standards are categorised into Application and Analytical Technique.
dot-red® Certified Reference Materials (CRMs) are produced under an ISO 9001 quality management system by an ISO/IEC 17025 and ISO Guide 34 accredited reference material producer. Standards are traceable to SI unit Kg and measured against NIST / BAM-CRM. Standards are also supplied with a certificate of analysis wherein the certified value(s) and uncertainty(ies) are determined in accordance with ISO Guide 31 [1], ISO Guide 35[2], EA 4/02 and Eurachem / CITAC Guides. The expiry date of the solution and where applicable information about levels of trace impurities are stated.
CRMs are supplied in transpiration control bags as standard.
