Abstract
Method 106 - Determination of Vinyl Chloride from Stationary Sources was evaluated in a two-part collaborative test. Gaseous samples, prepared in cylinders and containing interferences in some cases, were analyzed by a group of 10 collaborators. The results showed that Chromosorb 102/SF-96 columns performed better when acetaldehyde interference was present, but Chromosorb 102 alone was better when isobutane interference was present. Collaborator biases averaged 0.18 ppm (0.47 mg/cu m) low with a standard deviation of 0.72 ppm (1.86 mg/cu m). Both peak height and area measurements yielded similar results and the bias found was due entirely to low results from using Chromosorb 102 and not from the Chromosorb 102/SF-96 column. A three collaborator field test was conducted on the vent of a carbon bed absorber at a vinyl chloride polymer facility. The group had a standard deviation of 0.39 ppm (1.01 mg/cu m) and 0.24 ppm (0.62 mg/cu m) for sampling and analysis, respectively. Analyst skill is a major factor in the use of Method 106.

Contents Notes
A two-part collaborative test was conducted for Method 106, "Determination of Vinyl Chloride from Stationary Sources." A group of 10 collaborators analyzed a set of synthetic samples, some of which contained interferences, for vinyl chloride. Analytical results were reported by peak height and by peak area. All samples were analyzed on both 2m Chromosorb 102 and 2m Chromosorb 102/2m SF-96 columns. Most of the collaborators correctly identified the vinyl chloride peaks. Chromosorb 102/SF-96 performed better in the presence of acetaldehyde and Chromosorb 102 alone was better for isobutane interferences. In all cases the chromatograms showed proper responses. The errors that were made were due to interpretation of the results. The skill of the analyst is a major factor in the use of Method 106. The collaborators obtained values which averaged 0.18 ppm (0.47 mg/mp3s) low with a standard deviation of 0.72 ppm (1.86 mg/mp3s). There was no overall superiority noted for peak height versus area. The bias found was entirely due to low results using only Chromosorb 102. Chromosorb 102/SF-96 gave a bias that was 0.01 ppm (0.03 mg/mp3s) low. A field test of the method was then conducted by three groups on the vent from a carbon bed adsorber. The group of collaborators had a standard deviation of 0.46 ppm (1.19 mg/mp3s) for sampling and analysis combined. The standard deviation for sampling from the same source was 0.39 ppm (1.01 mg/mp3s) and 0.24 ppm (0.62 mg/mp3s) for the analysis of the samples obtained. A brief comparison of a charcoal adsorption tube method gave results which were about 20% lower than results obtained using Method 106.
