乙烯是植物界中分子最簡(jiǎn)單的激素，其主要的生理功能是促進(jìn)果蔬成熟、衰老(圖1-2)，被稱(chēng)為“成熟激素”。果蔬自身代謝就可以產(chǎn)生乙烯，當(dāng)貯藏庫(kù)中乙烯積累到一定水平時(shí)，就會(huì)啟動(dòng)果蔬后熟，加速衰老與腐爛，而且，這種作用是不可逆轉(zhuǎn)的。

Ethylene is the simplest hormone in the plant kingdom, and its main physiological function is to promote fruit and vegetable ripening and aging (Figure 1-2), known as the "ripening hormone". Fruits and vegetables can produce ethylene through their own metabolism. When ethylene accumulates to a certain level in the storage, it will initiate ripening, accelerate aging and decay, and this effect is irreversible.
This document specifies the gas chromatography method for determining the ethylene release rate during the storage of fruits and vegetables.
This document is applicable to the determination of ethylene release rate during the storage of fruits and vegetables.
Name: Capillary Chromatography Column
Fixed phase: 6% cyanopropyl phenyl+94% dimethyl polysiloxane
Sex: weak to moderate fixed phase
Equivalent to USP stationary phase G43
model: HH-624
Specification: 30m * 0.32mm * 1.8um
Application: Determination of Ethylene Release Rate during Fruit and Vegetable Storage by Gas Chromatography (GHT1405-2022)
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a capillary chromatography column for measuring ethylene release rate in fruit and vegetable storage. The column has high column efficiency and good separation, which meets the requirements for measuring ethylene release rate in fruit and vegetable storage. It has been installed and used on Agilent, Shimadzu, Thermo Fisher, Varian, Bruck, and PE with good results
