Coal Standards

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).

Certified Reference Materials

A variety of coal samples, certified for use as reference samples, are available from Vanguard Solutions, Inc. Each sample consists of 50 grams pulverized coal with NIST traceability and with multiple laboratory determinations. Certified reference materials are exceptionally well-suited for routine quality control checks and instrument calibration. Custom reference materials can be produced using consumer-specified coal sources, where equipment calibration customized to a primary coal source is desired.

Bias Testing of Mechanical Equipment

MAVILYN has over twenty years experience in the design, performance and evaluation of mechanical coal sampling systems. More than 300 tests have been performed on all types of systems in a variety of situations. The innovative use of non-intrusive testing methods results in less strain on coal loading and unloading systems, less site time, lower costs and more rapid turnaround of results.
