Volume 39, Number 3 (June 1985) Page 470-472
Pandey, H.D.; Prasad, M.S.
This paper describes a simple graphical calibration procedure for rapid determination of ash content in coal samples. The results obtained with this procedure are compared with those obtained earlier with the use of a regression equation. The two results are found to be in agreement.
