英國Hiden公司生產(chǎn)的CATLAB催化劑表征系統(tǒng),由兩部分組成:催化微反應(yīng)器和氣體分析質(zhì)譜(Microreactor-Mass Spectrometers)。
CATLAB可以進(jìn)行催化反應(yīng),吸附劑在反應(yīng)器中,通過通入不同的反應(yīng)氣體(如氫氣、氦氣、氮氣等)得到不同的反應(yīng)結(jié)果。逸出氣體由質(zhì)譜(QGA)進(jìn)行檢測,以得出反應(yīng)情況。然后通過軟件分析得到實驗結(jié)果。氣體的流量通過軟件設(shè)置。
質(zhì)譜QGA,質(zhì)量數(shù)1~200amu,可以進(jìn)行大多數(shù)的氣體檢測。可以單獨使用,也可以與其他儀器連接,進(jìn)行逸出氣體分析。
·快速響應(yīng),低熱量損失爐子
·的可互換的催化劑套管系統(tǒng)
·底座熱電偶,直接測量催化劑溫度
·質(zhì)譜與反應(yīng)器連接緊密,無死體積,方便蒸氣分析
·操作軟件自動控制儀器,同步獲得、顯示質(zhì)譜數(shù)據(jù)
·抗腐蝕管路結(jié)構(gòu)(選配)
· 1~20 ℃/min 加熱速率,至1000℃
·每一通道,獨立的質(zhì)量流量控制為3~100 ml/min,500ml/min為選配
·質(zhì)量數(shù)1~200amu(300amu選配)
·進(jìn)樣響應(yīng)時間小于500ms
·定量數(shù)據(jù)輸出PPM, PPB 或 %單位
·快速掃描100amu/s,用于瞬時分析
·自動/手動操作4氣流管路(可選配至8路)
