光譜分析儀基本優點

發布日期:2022-10-09 點擊率:80

  光譜分析儀是一種用于測量發光體的輻射光譜,即發光體本身的指標參數的儀器。

  光譜儀可以分為兩大類:經典光譜儀和新型光譜儀。經典光譜儀器是建立在空間色散原理上的儀器:新型光譜儀器是建立在調制原理上的儀器.經典光譜儀器都是狹縫光譜儀器。調制光譜儀是非空間分光的,它采用圓孔進光根據色散組件的分光原理。

  光譜分析儀基本優點:

  1.采樣方式靈活,對于稀有和貴重金屬的檢測和分析可以節約取樣帶來的損耗。

  2.測試速率高,可設定多通道瞬間多點采集,并通過計算器實時輸出。

  3.對于一些機械零件可以做到無損檢測,而不破壞樣品,便于進行無損檢測。

  4.分析速度較快,比較適用做爐前分析或現場分析,從而達到快速檢測。

  5.分析結果的準確性是建立在化學分析標樣的基礎上。光譜分析儀
