Inorganic standardsSingle and multi-element inorganic standard solutions for atomic absorption, ICP, XRF, and other techniques. Ion chromatography and flame photometry standards are included.
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 , ISO Guide 35, 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 and other materials are supplied in transpiration control bags as standard where appropriate.
Atomic absorption standards, single element at 1g/L (1,000 ppm) concentrationSingle element inorganic solutions suitable for calibrating all makes of atomic absorption spectrometers at 1000ppm /1g/L and 10,000ppm / 10g/L levels.
See ICP and AAS, multi-element for multi-element calibration materials.
Atomic absorption and ICP instrument performanceCRM/calibration standards for checking and verification of atomic absorption (AAS) and Inductively-Coupled Plasma (ICP) instrumentation. Includes ionisation buffer solutions, matrix modifiers, blanks/dilution solutions and others.
