Aw� CPC CARS 2003 CertrMcation Tenting Pao*T 4.1.U. Qddes of Nilrogen Measurements CARE Method 100 was used to measure NOx concentrations at the required so=efs). in this method, exhaust gas Is extracted from the stack and passed through a gas CorMkg dng system. The dean and dried We gas sample Is then directed to a Chemilumirmcent NO/NOS monitor for and"IL The anaF zw selected for this parfonrsgrlca demonstration was the Coftmia Anolyticd Instruments(CAI).Model 400CLD, ChOmilurninescont NOINOx Monitor or*no= The CAI Model 400CLD operation is bated on the principle of the C1191111111LIM10109CWt reaction of nitric oxide (NO) and ozone. Light emission results when eloctrard oWy excited nitrogen dioxide fNO2)molecules revert to their ground atote. To measure NO concentrations, ft gas sample to be OrK yred is blended with ozone (o,) in the lnstrunent's reaction chamber. The resulting chemNumineseence is monitored through an optical tater by a highly sensitive phtotorrwftjor (PMT) positioned atone end of the reaction chamber. The fuer/PhetomLrltipAer aon�binbtion responds to light in a narrow wavelength bond unique to the chemiluminescent reaction (detailed below) and the optical filter assists in eliminating interferences in thio wavelength. 70 measure NOx concentrotlons (NO plus 1404 the sample gas flow Is diverted through a NOrto-NO converter that is passed to the reaction chamber. Tho chemiluminescent retpanse, measured by the photomutitpl er,is Hnearty PmPwf anal to the NOx concentration entering the converter. The system was + operated in the NOx mode during art phases of the program. 4.1.1.4. Carbon Monoxide Measurements CARE Method 100 was used for the measurement of CO levels from the BiOMax 50, In this method,dean and dried stack gas is passed to an Infrared CO monitor for analysis. A Thermal Bectron Inc, (M) Model 48C Infrared CO Monitor was used for these measurements. This instrument uses a technique based an the Infrared absorption characteristics of CO to measure concentration. A single beam of Infrared light Is Passed through a sample CON contalxlxg sample gas to be measured. In passing through the sample cell the beam is ottenuoted by the amount of energy absorbed by the gas(es)in the sample.Changes in CO concenfratign result In Proportional changes in beam intensity. The remaining energy in the beam is Passed serially through two cavities of an infrared detector and a moss-flow sensor filled with reference CO gas- Electronic pWOCOsstng and tinearidng of the imbalance signal are used to generate an elechicol output signal Ilnearly proportional to the concentration of the sample gas. 4.1.1.5. Volalite Organic Compound Measurements CARB Method was used for the measurement of VOC. In this procedure.a flame Ionization detector(FID) manitar Operates and measues total hydrocarbon concentrations on a continuous basis. The measurement system is an oven heated FID which has an key gas interface components (pump,SS Mier, sample nine) heated at or above one hundred and fifty (150) degrees centigrade (°C). By hoofing ani components that meet the sample delivered to the system,It eliminates the Potenttai for condensation or contamination of the gas. This also eliminates any bias that may come from variation in the hunidlty or temperature of the gas sample. In the Word application,a gas sample Is drown from the source through a heated sample One to a flame Ionization detector. lona formed in the combustion of a specific hydrogen-carbon compound In a H?02 , flame establish a current that is proportional to the mass flow rate of the hydrocarbons to the flame. This current (flame response) Is Compared with a calibration curve. The results are reported as equivalents of carbon or in temns of the Calibration standard. report TRC ENVIRONMENTM.CORPORATION 496j*0X0 O= C..NProieds\CAC 49614000o-OL1MDo=\CPC Womax so Report ver-240C n�
