Proximate analysis tests conducted in SGS laboratories, along with applicable standards, include:
Ultimate analysis tests produce more comprehensive results than the proximate analyses. SGS uses the results from ultimate analysis tests to determine the elemental composition of the coal including moisture, ash, carbon, hydrogen, nitrogen, sulfur, and oxygen (by difference). We determine each element through chemical analysis and express it as a percentage of the total mass of the original coal or coke sample.
SGS is a global leader in chemical analysis for the coal and coke industries. Proximate and ultimate analyses done in our state-of-the-art laboratories deliver timely, accurate and independent results from your coal, coke and biofuel samples.
