Sample bottles made of PP are ideally suited for the analysis of PFAS. The adsorption effects are low with plastic bottles and the signal strengths of the analytes are high. Polypropylene bottles are therefore better suited for PFAS analysis than glass bottles or silanized glass bottles.

Here, we propose the use of amino- and fluoro-silanized autosampler vials to reduce hepcidin interaction to laboratory glassware surfaces after testing several types of vials for the preparation of stock solutions and serum samples for isotope dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS).

Silanized Chromatography Vials. Because the surface of laboratory glassware is slightly acidic, it can adsorb some analytes — particularly amines. In low level analyses, such losses can be significant. To prevent sample loss through adsorption, glassware used in low level analyses usually is silanized. Silanization masks the polar Si-OH groups on the glass surface by chemically binding a nonadsorptive silicone layer to the surface, in effect “derivatizing” the glass.

Apr 12, 2011 · In our case, it's to avoid adsorption of cannabinoids to the glass container during extraction. A procedure of silanization : Prepare a solution of diméthyldichlorosilane (Sigma D-3879) at 5% in toluene. Introduce this solution in the glass container and shake 10 min. Rince with toluene.

Feb 24, 2022 · Case 3 encountered the adsorption of a basic analyte on non-silanized glass vials. A hydrophilic interaction chromatography (HILIC) LC-MS method was developed to monitor a piperazine impurity that was potentially present in benzoyl piperazine hydrochloride, a regulatory starting material (RSM) for the synthesis of Compound 3, at a reporting limit of 0.01 wt%.
