全球檢測(cè)限和靈敏度最高的植物乙烯測(cè)量系統(tǒng)
最適合超高靈敏度測(cè)量，特別是連續(xù)監(jiān)測(cè)
?主要功能
該系統(tǒng)主要用于植物研究的乙烯監(jiān)測(cè)，如生長(zhǎng)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(chǔ)存、抗逆性研究(干旱、高溫、重金屬)等。其中檢測(cè)儀ETD-300結(jié)合激光技術(shù)與聲學(xué)照相技術(shù)，實(shí)時(shí)快速測(cè)量乙烯(C2H4)氣體絕對(duì)濃度；閥門控制箱VC-6完全自動(dòng)化和電腦控制，接一個(gè)即可以使單個(gè)氣體檢測(cè)儀實(shí)現(xiàn)6個(gè)樣品的同時(shí)測(cè)量，單個(gè)乙烯檢測(cè)儀可以接一個(gè)或多個(gè)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(cè)領(lǐng)域。特別適合植物生理、發(fā)育研究的超靈敏乙烯測(cè)量。
