Analysis of Vinyl Chloride Personal Monitor Samples The analyses of the carbon tube personal monitor samples which arrived on June 18, 1974 have been completed. Department 8506 has analyzed these 13 carbon tube samples for adsorbed vinyl chloride. The following table gives the results of the analyses. These samples have been given a log number of 32. Please state that number in any inquiry about them. Sample Number Sampling Building Job Class Sampling Time (min) Vinyl Chloride Concentration mg PPm 19 Mass Dead Tech.
