Who would use RSA Vials?
Vials and inserts manufactured with RSA Glass™ have reduced surface activity due to the elimination of the layer of silica that results when vials are normally manufactured and many of the surface metals that contaminate analysis and have detrimental effects on your results.
When using ordinary borosilicate glass autosampler vials and inserts, sample diluents (such as water) can de-protonate the many hydroxyl groups on the wall of your vial which produces a negative charge on the glass. The “acidic” functionality of these silanols has been known to cause adsorption of basic compounds, change the pH of the sample solution and/or hydrolyze some susceptible compounds making them undetectable. The surface metal contaminants can cause precipitation, chelation or other changes in your samples while in the vial.
With RSA Glass™ vials and inserts there is virtually no “loss to the vial”, no “pH shifting” or other problems thus making your analysis more reliable, lot to lot, run to run and day to day. Avoid frustration of unreliable data.
RSA™ autosampler vials and glass inserts are manufactured without using any coating of any type making them an excellent choice for LC, LCMS, GC and GCMS compared to coated vials for many applications.
