Abstract
An account is given of the collaborative work undertaken by brewing laboratories on behalf of the Analysis Committee of the Institute of Brewing and by National Coal Board laboratories with a view to obtaining a reliable method for the determination of arsenic in malting coal. The accuracy of the result is dependent not only on the method of analysis but also on obtaining a truly representative sample. An extensive survey has indicated that, in the sampling of large malting anthracite, an error of considerable magnitude can be introduced even when sampling is carried out by the British Standard procedure. This work has resulted in the development of a colorimetric method by the National Coal Board and of a paper-stain Gutzeit modification by the brewing industry. Both procedures have been accepted by the Committee of the British Standards Institution as accurate methods for the estimation of arsenic in malting coal, and will be included in the forthcoming revised edition of the British Standard 1016.
