\rGC-7800PDD<\/span>氦離子化氣相色譜儀<\/span>
\rGC-7800PDD<\/span>氦離子化氣相色譜儀適用于高純氣體、超高純氣體及電子工業(yè)用氣體中痕量雜質(zhì)的檢測。該產(chǎn)品以<\/span>GC-7800<\/span>氣相色譜儀為載體，配備<\/span>VALCO<\/span>公司生產(chǎn)的氦離子化（<\/span>PDHID<\/span>）檢測器；采用普瑞公司擁有專業(yè)技術(shù)的四閥五柱的中心切割與反吹技術(shù)，其中的所有進樣和切換閥均為<\/span>VALCO<\/span>公司生產(chǎn)的帶吹掃保護氣路的六通或十通閥；上述部分與<\/span>VALCO<\/span>公司原裝的氦氣純化器、無死體積取樣閥等部件一起組成一套完整的高純氣體分析整體及解決方案。<\/span>
\r<\/span>高純氣體的分析是一個復雜的過程，不僅需要高靈敏的檢測器，還要考慮樣品本身的特性及其背景，如吸附、取樣及分析過程中是否有空氣混入、系統(tǒng)的密閉性、系統(tǒng)的死體積等環(huán)節(jié)，普瑞色譜公司總結(jié)了高純氣體分析過程中的技術(shù)難點，并給出了所有難點的解決措施，使<\/span>GC-7800PDD<\/span>氦離子化氣相色譜儀成為**專業(yè)的高純氣體分析系統(tǒng)，很好的完成了氣體中微量雜質(zhì)，特別是<\/span>ppb<\/span>級的雜質(zhì)的分析。<\/span> <\/span>\r<\/p>\r
