Certified Reference Materials and Calibration Standards for Coal and Coke Laboratories
Vanguard Solutions, Inc. and its subsidiary, www.Coalstandards.com bring over 30 years experience in the manufacturing and certification of coal and coke standards.
We have a large catalog of in stock standards and the lowest prices.
Samples consist of material with NIST traceability and multiple laboratory determinations. Certified reference materials and calibration standards are exceptionally well-suited for routine quality control checks and instrument calibration.
Custom reference materials can be produced using consumer-specified sources, where equipment calibration customized to a specific source is desired (inquire about pricing).
