檢測限和靈敏度zui高的植物乙烯測量系統
超高靈敏度測量，特別是連續監測
主要功能
該系統主要用于植物研究的乙烯監測，如生長發育、基因表達、植物病原體的相互作用、與其他植物激素的相互作用、蔬果收貨后儲存、抗逆性研究（干旱、高溫、重金屬）等。其中檢測儀ETD-300結合激光技術與聲學照相技術，實時快速測量乙烯（C2H4）氣體濃度；閥門控制箱VC-6*自動化和電腦控制，接一個即可以使單個氣體檢測儀實現6個樣品的同時測量，單個乙烯檢測儀可以接一個或多個閥門控制箱；烴分解器CAT-1則利用鉑金顆粒催化烴氧化分解為水蒸氣和CO2，為系統提供無烴干擾的樣品空氣。
應用領域
用于環境、醫學、農業、工業、生態、生物等監測領域。特別適合植物生理、發育研究的超靈敏乙烯測量。
