The methods used for laboratory control analyses in the operation of a unit for the separation of boron isotopes by the fractionation of dimethyl ether--boron trifluoride complex are described and evaluated. Procedures developed at the S.A.M. Laboratories of Columbia University for the determination of boron, fluorine, and dimethyl ether in this complex have been applied with only minor modifications. Procedures for the determination of impurities in the complex have been developed. Hydroxyl and alkoxyl groups are determined by methods employing the Karl Fischer reagent. Metals are determined by the conventional methods of colorimetric, volumetric, and gravimetric analysis. Conductivity measurements are also used in analytical control. Consideration has been given to other impurities which might be expected to appear in the complex. Data have been presented to show the precision and accuracy of the methods. Consideration has been given to the chemical information obtainable from the analyses. Most of the methods are capable of further improvement. A great deal of further information is required before the chemical reactions of the impurities in dimethyl ether--boron trifluoride complex are completely understood. Some suggestions have been made as to the directions which further investigations might take.
