Chromatography is an invaluable analytical technique used in numerous fields of science and industry for separating, identifying and quantifying components within mixtures. A key component of chromatographic systems is sample vials; within these vials are glass inserts which play an integral part in producing accurate and reliable results. In this article we'll explore why glass inserts are so integral in achieving accurate and reliable results using Chromatography.

Minimizing Sample Contamination:

Glass inserts can help minimize sample contamination risks in chromatography experiments. Because samples can be susceptible to reacting with vial materials, using glass inserts ensures that only an inert surface comes into contact with them and minimizes unwanted reactions or adsorption events.

Preserving Sample Integrity:

Glass' inert properties help preserve sample integrity. Glass inserts do not introduce impurities into the sample, ensuring that chromatographic analysis reflects its true composition without interference from vial itself.

Reducing Surface Activity:

Glass has low surface activity when compared to plastic materials, helping maintain consistent and reliable separation processes. Surface activity can cause the analytes in vials to adhere to vial walls, potentially altering accuracy and reproducibility of results; glass inserts help keep this from occurring by maintaining consistency in their approach to separation processes.

Enhancing Sample Recovery:

Glass inserts help increase sample recovery by limiting interactions between samples and vials, which is especially crucial in trace analysis where even minor losses of sample can significantly compromise sensitivity of analysis.

Compatibility with Varied Sample Types:

Glass inserts are adaptable and suitable for testing a wide variety of sample types, including volatile and nonvolatile compounds. Their adaptability enables them to perform consistently across many chromatographic applications for improved analytical outcomes.

Temperature Stability:

Glass boasts outstanding temperature stability, making it suitable for chromatographic applications requiring the manipulation of temperatures across a broad spectrum. This ensures reproducible separations using methods requiring temperature regulation.

Resistance to Chemical Attack:

Glass inserts offer excellent chemical protection from solvents and reagents commonly used for chromatography analysis, protecting vials from leaching or degradation that might compromise the quality of analysis. This feature ensures a long lifecycle of vials with glass inserts inside.

Easy Visual Inspection:

Glass inserts offer clear and transparent views of samples for easy visual inspection, enabling quick verification that they have been loaded properly and do not contain air bubbles that might affect separation processes. This feature ensures proper loading as well as verification that air bubbles or any other issues that could impede separation aren't present during processing.

Glass inserts have long been utilized in chromatography due to their precision, reliability and sample integrity benefits. As glass inserts serve a critical function in mitigating contamination risk while maintaining sample integrity while producing consistent and accurate results, their choice remains key for optimal performance and reliability of chromatographic analyses.
