Proprietary Cleaning Treatment Suppresses Sample Adsorption by the Vials
Are your peaks sometimes unstable or smaller than expected? Depending on the vial, it is possible that the sample is being adsorbed by the inner surface of the glass, which can reduce the recovery ratio. Shim-vials H and S are made from medical grade borosilicate glass, certified as Type 1 glass in the U.S. Pharmacopoeia (USP), and sample adsorption is suppressed by the application of a proprietary cleaning treatment. An additional cleaning process is applied to the Shim-vial H glass to suppress adsorption to the utmost. Accordingly, these are the optimum vials for LC-MS when performing trace-quantity analysis. Using these revolutionary vials enables more accurate and stable analysis results.
