檢測限和靈敏度zui高的植物乙烯測量系統(tǒng)

超高靈敏度測量，特別是連續(xù)監(jiān)測

主要功能

該系統(tǒng)主要用于植物研究的乙烯監(jiān)測，如生長發(fā)育、基因表達(dá)、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(jié)合激光技術(shù)與聲學(xué)照相技術(shù)，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(xiàn)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(tǒng)提供無烴干擾的樣品空氣。

應(yīng)用領(lǐng)域

用于環(huán)境、醫(yī)學(xué)、農(nóng)業(yè)、工業(yè)、生態(tài)、生物等監(jiān)測領(lǐng)域。特別適合植物生理、發(fā)育研究的超靈敏乙烯測量。

產(chǎn)品特點 ● 實時測量，連續(xù)無間斷監(jiān)測 ● 測量范圍：0-5ppmv，檢出限：0.3ppbv ● 靈敏、快速、穩(wěn)定性好，無干擾 ● 操作簡便，結(jié)實耐用，所需維護(hù)少 ● 友好的用戶操作軟件界面

系統(tǒng)組成

乙烯氣體檢測儀ETD-300

閥門控制箱VC-6

烴分解器CAT-1
