　　SIPROCESSUV600
　　
　　SIEMENS德國于2012年10月1日在大陸推出新款紫外在線分析儀SIPROCESSUV600.其特點顯著，測量精度比紅外在線分析儀的精度更高、更準確。
　　
　　ContinuousgasanalysisforUV-activegases
　　
　　Individualorsimultaneousmeasurementofuptothreecomponents:
　　
　　NO,NO2,SO2andH2S
　　
　　Applications
　　
　　•Emissionmeasurement
　　
　　-MeasurementoflowNOconcentrationsinpowerstationsandgasturbines
　　
　　-MonitoringofNOxindenitrificationplantsbydirectmeasurementofNOandNO2aswellasacombinedNOxvalue
　　
　　-Efficientmeasurementindenitrificationplants
　　
　　-RegisteringoflowestSO2andNOconcentrations
　　
　　-Emissionmeasurementinthepulpandpaperindustry
　　
　　•Processcontrol
　　
　　-Measurementofsulfurcompoundsinprocessgasinthepaperandpetrochemicalindustry
　　
　　-NOandNO2measurementinapplicationsinnitricacidproduction
　　
　　-OptimizationofNOxemissionsintheexhaustgasoftheautomotiveindustry
　　
　　-H2SandSO2measurementinresidualgaspurificationofsulfurrecoveryunits（SRU）
　　
　　-MeasurementofsulfurcomponentsinClausplants
　　
　　-HighH2Sconcentrationsinreactiveorsourgases
　　
　　Benefits
　　
　　•SimultaneousmeasurementofNOandNO2withsubsequentcompilation.NO2convertersorCLD
　　
　　analyzersarethusnotrequired.Therefore:
　　
　　-Lowermaintenanceeffort（noconverterfunctioncheck）
　　
　　-Reducedoperatingcostsbecausenoadditionalequipmentrequired,e.g.ozonegenerator,etc.
　　
　　•MeasurementintheUVrange
　　
　　-MeasurementnotaffectedbyH2OandCO2
　　
　　-VerylowSO2andNOmeasuringrangespossible
　　
　　•UVResonanceAbsorptionSpectrometry（UVRAS）
　　
　　-MeasurementofverylowNOconcentrations:Measuringrange10ppm
　　
　　-Verylowcross-sensitivitytoothergases
　　
　　•VerylongservicelifeofUVlamp（typically2years）
　　
　　•Lowdriftsandhighstabilityby
　　
　　-four-channelmeasuringmethodanddoublequotientcalculation
　　
　　•Truereferencemeasurementfordrift-free,stablemeasurement
　　
　　•Allmodules“temperaturecontrolled”;therebyindependentofambienttemperaturefluctuations
　　
　　•Optionaladjustmentdevice

　　此款紫外在線分析儀的缺點：
　　
　　1.不可以防爆，
　　
　　2.只能單獨測一種氣體，
