INSTRUMENTAL DEVELOPMENT OF ULTRA-HIGH PERFORMANCE NOx ANALYZER USING LASER INDUCED FLUORESCENCE TECHNIQUE

Ultra High Performance NOx Analyzer Using Laser Induced Fluorescence Technique Was Developed。DIODE LASER Pumped Nd的仪器套件：YAG LASER，激光通量的校正系统，生命细胞，生命收集选择，光子计数系统，真空系统，和系统控制和数据获取的个人计算机。“我们优化了这些组件，并为下降而制造了力量--调节了仪器。THE INSTRUMENT CAN MEASURE AS LOW AS3.8 PPTV OF NO-D22-D2 FOR 1 MIN. INTEGRATION。我们把这个仪器带到了冲绳原子能站，那里的空气是非常干净的，NOx水平是非常低的。“我们成功了测量干净的人类海洋氮氧化物概念。”与不同的原则的Intercomparison with Technique AND Got Quite良好的资源，我们将这个仪器结合在一起是实用的，安静的，足够可靠的计量远程清洁空气样品。

ULTRA HIGH PERFORMANCE NOx ANALYZER USING LASER INDUCED FLUORESCENCE TECHNIQUE WAS DEVELOPED. THIS INSTRUMENT COSISTS OF DIODE LASER PUMTPED Nd:YAG LASER, CORRECTION SYSTEM OF LASER FLUCTUATION, LIF CELL, COLLECTION OPTICS FOR LIF, PHOTON COUNTING SYSTEM, VACUUM SYSTEM, AND PERSONAL COMPUTER FOR SYSTEM CONTROL AND DATA ACQUSITION. WE OPTIMIZED THESE COMPONENTS AND MADE EFFORTS FOR DOWN-SIZING THE INSTRUMENT. THE INSTRUMENT CAN MEASURE AS LOW AS 3.8 PPTV OF NOィイD22ィエD2 FOR 1 MIN. INTEGRATION. WE BROUGHT THIS INSTRUMENT TO THE OKINAWA ATMOSPHERIC STATION WHERE AIR IS VERY CLEAN AND NOx LEVEL IS VERY LOW. WE SUCCEDED TO MEASURE CLEAN HUMID MARIN NOx CONCENTRATION. INTER-COMPARISON WITH DIFFERENT PRINCIPLE OF TECHNIQUE AND GOT QUITE GOOD RESULT AND WE CONCLUDED THIS INSTRUMENT IS PRACTICALLY QUITE USEFUL AND RELIABLE ENOUGH TO MEASURE REMOTE CLEAN AIR SAMPLE.
