Ethylene Oxide Residual Gas Chromatograph

The ethylene oxide residual gas chromatograph is a professional analytical instrument for detecting the residual amount of ethylene oxide in medical-related products.

Instrument composition

Gas source system: 

Provides stable carrier gas (such as nitrogen), fuel gas (such as hydrogen) and auxiliary gas (such as air) to ensure the normal operation of chromatographic separation and detection.

Injection system: 

Including injector and vaporization chamber, accurately inject and instantly vaporize the sample so that it can be brought into the chromatographic column by the carrier gas.

Chromatographic column system: 

The chromatographic column filled with stationary phase is the key component to achieve the separation of ethylene oxide and other components. Different types of chromatographic columns have an important influence on the separation effect.

Detection system: 

The commonly used hydrogen flame ionization detector has high sensitivity to carbon-containing organic compounds and can accurately detect ethylene oxide.

Data processing system:

Collect, process and analyze the signals generated by the detector, and present the residual amount of ethylene oxide results in the form of intuitive graphs and data.

Application fields

It is mainly used in the medical device industry, such as syringes, infusion sets, masks and other products sterilized with ethylene oxide. The residual amount needs to be detected to ensure that the products meet safety standards and protect the health of patients and medical staff; it is also used for quality control in related fields such as pharmaceutical packaging materials.

Ethylene oxide is a toxic carcinogen. Excessive residues will be released during use and cause harm to the human body. The instrument can accurately detect the residual amount, effectively control product quality, reduce medical risks, and ensure the safety and effectiveness of medical supplies.
