THE DIRECT DETERMINATION OF CHEMICAL SOLVENTS IN COATING MATERIALS BY MEANS OF GAS CHROMATOGRAPHY
THE USE OF A PACKED COLUMN VAPOR PHASE CHROMATOGRAPH APPLIED TO THE PRELIMINARY IDENTIFICATION OF CHEMICAL SOLVENTS DIRECTLY IN PAINT IS DESCRIBED. USING A NEW TECHNIQUE A PIGMENTED PAINT WITHOUT PRELIMINARY TREATMENT IS DIRECTLY INTRODUCED INTO A GAS-LIQUID CHROMATOGRAPH AND THE EVOLVED SOLVENTS DIRECTLY PASSED THROUGH THE COLUMN WHERE SEPARATION AND ANALYSIS TAKES PLACE. RESULTS OF PRACTICAL UITLITY HAVE BEEN ACHIEVED. STANDARDIZATION OF THE INSTRUMENT IS DESCRIBED. DATA OBTAINED ON A NUMBER OF DIVERSE TYPES OF TEST PAINTS INDICATE RELIABILITY AND UTILITY OF THE TECHNIQUE. THE DATA ARE REPORTED AND THE AREAS OF UTILITY OF THE METHOD DISCUSSED. THE TECHNIQUE HAS BEEN USED TO RECTIFY CERTAIN PRODUCTION PROBLEMS AND TO EVALUATE SOLVENTS IN PAINTS OF UNKNOWN ORIGIN. THESE RESULTS ARE DISCUSSED. /JPT/
