Liner Regeneration and Surface Treatment of Glass
Liner Regeneration
Turn old into new!
What do you do with used liners at the end of their service life? New liners are very expensive, especially with more unusual geometries for special applications; the regular purchase of new liners can be a considerable cost factor. This is why we exclusively offer the regeneration of used liners. This saves costs and avoids unnecessary waste.
For regeneration, the used liners are first thoroughly cleaned, then deactivated and finally conditioned so that they are immediately ready for use again. If glass wool is introduced into the liner, this is done before deactivation to prevent the formation of active surfaces. Liners can be regenerated many times this way without any loss of performance, which results in considerable cost savings. Special requests, such as the insertion of glass wool at different positions in the liner and the insertion of packing materials, are also possible according to customer requirements.
The customer’s requirements are fully considered when deactivating the liners. This is why we offer a selection of different deactivation processes. In addition to the tried and tested Sil deactivation, which corresponds to the standard deactivation of new liners, the high-quality INNO-Sil process and PM-Sil deactivation, which is particularly suitable for polar analytes, are also available.

Surface Treatment of Glass
It’s the surface that counts!
Glass is an active material, to the surface of which a variety of analytes can bind. This can have a negative effect on analytical results, ranging from falsification of the sample composition to complete adsorption of sample components. The silanization of GC liners has long been essential to minimize this problem in the injector. However, it is often neglected during sample preparation and storage. This effect often leads to falsified analysis results, especially in the trace analysis of pesticides and sensitive substance classes such as amines, phenols, steroids, proteins, and others. The deactivation of the glass surface can provide significantly improved results here.
We offer a range of deactivation methods, each of which is optimized for specific applications. For example, standard, non-polar Sil deactivation is sufficient in most cases to prevent the interaction of analytes with silanol groups on the glass surface. Depending on the analyte, however, medium-polarity phenyl-methyl (PM) silanization may also be more suitable. For particularly high demands, for example in pesticide analysis, high-quality INNO-Sil deactivation is available, which ensures maximum inertness of the glass surface.
In the pharmaceutical industry, siliconization is a long-established process for creating a durable inert protective layer for glass surfaces.
We also offer HCl treatment of glass surfaces to remove metal ions and basic impurities to which some analytes could bind, e.g. through complexation, or which could contaminate the sample.
In principle, all glass surfaces can be treated with the surface treatment processes mentioned. In addition to glass bottles, GC liners and glass wool, we offer the treatment of almost any other glass parts; other deactivations are also possible. We would be happy to advise you on this and provide you with a customized offer.
