THE APPLICATION OF GAS CHROMATOGRAPHY TO THE ANALYSIS OF COATING SOLVENTS

THE RAPID AND SIMPLE SEPARATION AND IDENTIFICATION OF THE VOLATILE FRACTIONS OF COATING COMPOSITIONS HAVE BEEN MADE POSSIBLE BY GAS CHROMATOGRAPHY. THIS PAPER IS CONCERNED WITH A NUMBER OF ASPECTS OF THE SUBJECT. A STUDY IS PRESENTED OF THE PRINCIPLES, APPARATUS, COST, OPERATING CONDITIONS AND SAMPLE PREPARATION FOR THE ANALYSIS OF COATING COMPOSITIONS. FOR QUALITATIVE IDENTIFICATION OF SOLVENTS, RELATIVE RETENTION TIME DATA ABSTRACTED FROM THE LITERATURE, TOGETHER WITH NEW DATA, ARE TABULATED FOR THREE COLUMNS: AN ESTER, A SILICON AND POLYALKALENE GLYCOL. DATA FOR 21 OTHER COLUMNS ARE ALSO GIVEN. ESSENTIALLY, ALL SOLVENTS USEFUL IN THE PROTECTIVE COATING INDUSTRY HAVE BEEN INCLUDED. THE USE OF CONFIRMATORY TECHNIQUES AND QUANTITATIVE APPLICATIONS ARE ALSO DISCUSSED. AN EXAMPLE ILLUSTRATES THE STEPS IN THE COMPLETE ANALYSIS. /AUTHOR/
