Method Total Hydrocarbon Analyzer with Flame Ionization Detector Table I COMPARISON OF FIXED MONITORING INSTRUMENTS Advantages of Method_____________________________________ Disadvantages of Method^ 1. Outstanding sensitivity (0-1 ppm full scale) 2. Linear response (2% full scale) 3. Good reproducibility (2% full scale) 4. Rapid response time (almost instantaneous) and cycle time 5* Easy to operate, low maintenance requirements 6. Moderate cost ($2000 w/o recorder) l. Not specific for VCM Gaa Chromatograph Infrared Spectrometer w/20m Gas Cell 1. Good sensitivity (low ppm) 2. Acceptable response; good reproducib11ity 3. Specific for VCM 1. Excellent sensitivity [0.7 ppm MDL^] 2. Acceptable response; good reproducibility 3. Specific for VCM 1. Longer cycle time (5-10 min.) 2. More complex equipment 3. More difficult to operate and maintain 4. More expensive 1. Longer cycle time (5-10 min.) 2. More complex equipment 3. More difficult to operate and maintain 4. More expensive UCC 094017 Combustion-Conductivity Method 1. Good sensitivity (low ppm) 2. Specific for halogens ^ as compared with the Total Hydrocarbon Analyzer Minimum Detection Limit 1. Not specific for VCM 2. Longer cycle time 3; Requires excessive operator attention and maintenance 4. Not commercially available Method Organic Vapor Analyzer (OVA) with flame ionization detector Table 11 COMPARISON OF PORTABLE SURVEY INSTRUMENTS Advantages of Method 1. Good sensitivity (low ppm) 2. linear response (1-1000 ppm) 3. Good reproducibility 4. Rapid response (almost instantaneous) 5. Light weight; easily portable 6. Easy to operate and maintain 7. Moderate cost (<$3,000) Disadvantages of Method^^ ,1. Not specific for VCM 2. Not approved for use in a Class 1 Group D work area^12^ Gas Chromatography Infrared Spectrometer w/20m Gas Cell 1. Good sensitivity (low ppm) 2. Acceptable response; good reproducibility 3. Specific for VCM 4. Excellent for multi-component mixtures 1. Excellent sensitivity [0.7 MDL^] 2. Linear response; good reproducibility 3. Specific for VCM 4. Good for multi-component mixtures Catalytic Oxidation 1. Easily portable 2. Explosion proof 3. Good response at high concentrations (1) as compared with the Organic Vapor Analyzer Requires Hot Work Permit Minimum Detection Limit i 1. Lacks instantaneous response for leak detection 2. Not as easily portable as OVA 1. Lacks instantaneous response for leak detection 2. Not easily portable 3. Not explosion proof; requires exclosure with N2 or air purge 1. Lacks sensitivity (not reliable below 50 ppm) 2. Bad zero level drift UCC 094018 PROPOSED VINYL ANALYZER SYSTEM Figure 1 UCC 094019 / UCC 094020 MlBY. DATE CHKD. BYDATE.
