ELEMENTAL ANALYSIS OF ORGANIC MATERIALS BY X-RAY SPECTROMETRY

Advantages and disadvantages of different methods for the elemental an alysis of organic materials (petroleum and petrochemical products, org anometallic and high-molecular compounds, medicines, etc.) are conside red on the basis of the data reported in the literature. The high effi ciency of X-ray spectrometry is demonstrated. The sources of random an d systematic errors in the analysis of the above materials by X-ray sp ectrometry are discussed, and techniques for their elimination are out lined. Particular attention is given to methods for sample preparation and to techniques for constructing calibration plots. The performance characteristics of X-ray spectrometric procedures (precision and accu racy of the results of analysis and detection limits) are presented.
