The Importance Of The Sample Vial During The Experiment

The material of the sample vial

The glass sample vials are most frequently seen. When talking about the material, we must first talk about the linear expansion coefficient, which means that the temperature changes every time the temperature changes. The coefficient of thermal expansion of glass depends essentially on glass’s chemical composition and also its thermal history.

The glass expansion coefficient determines the ability to resist quenching and heat. In short, it is the ability of glass to withstand severe temperature changes. The coefficient of linear expansion is inversely proportional to the temperature change that the glass can withstand.

The importance of the sample vial during the experiment

Although the sample vial does not seem to be insignificant compared to many sophisticated analytical instruments used in the laboratory, the incorrect use of the sample vial has a significant impact on the experiment, resulting in the reduction of experimental efficiency and repeatability.
Potential problems with the incorrect use of sample vials include:

• Loss of analyte due to volatilization
• Chromatographic peaks caused by solvent and septum
• Mechanical damage to the autosampler
• Sample degradation
• Poor repeatability of injection, etc.
