Sample preparation method and Laboratory sampling procedures involve either: Coning and Quartering; or Riffling Method. Coning and Quartering for sample preparation techniques/method The method which is used for sampling large quantities of material say 20kg, consists of pouring or forming the material into a conical heap upon a solid surface ( a steel plate) and relying on radial symmetry
The normal preparation procedure requires that each airdried coal sample pass through a jaw crusher; one subsample (split) of the crushed material (2 to 4 mm, or 5 to 10 mesh) is then taken for the ultimate and proximate analyses, and another split is reduced to approximately 150 m m (100 mesh) by a vertical grinder for chemical analysis.
Coal sampling and anaylsis standards, CCC/235 IEA Clean Coal provide guidelines for coal sampling procedures under different conditions, sample preparation and bias test other words, there is a requirement that reliable standard test methods be applied to coal analysis.

Indian Standard METHODS OF TEST FOR COAL AND COKE PART 1 PROXIMATE ANALYSIS ( Second Revision) e, FOREWORD This Indian Standard ( Part 1 ) Where airdrying has been adopted in the preparation of the samples, the percentage loss of moisture in
coal samples, such as brown coal, the sample preparation step becomes even more important in ensuring reproducible analysis results. The fineness of the sample can influence the standard deviation of the analysis results, as will be shown in this article using brown coal as an example. In general, using a sample divider to

The sampling system should be set to collect at least the sample mass specified in the standard during one hour test periods.
B. Preparation and analysis of coal samples. i. Modalities for storage and preparation of joint samples would be strictly as per guidelines given by Coal Controller office/Bureau of Indian Standards(BIS). Provisions of above modalities are already laid down in FSA. Ii. Preparation of coal samples collected by third party samplers shall be

The sampling system should be set to collect at least the sample mass specified in the standard during one hour test periods. All of the proper protocols for sample preparation and analysis must be used and documented, and the OLA data collection must be in accordance

The principal sample preparation methods used for metal determination in coal and coal products by spectroanalytical techniques, besides direct analysis, are dilution with organic solvents, dilution in threecomponent systems (emulsion or microemulsion), dry ashing and wet acid digestion. Direct analysis using little or no sample preparation is most suitable for ETAAS with a graphite tube furnace and XRF
