glass GC-MS vials agent

1 ng/mL and lower MS/MS, Tof TruView LCMS Certified Vials Type 1, 33-Expansion Borosilicate Glass Analytical laboratories use type 1, 33-expansion glass, the most chemically-inert glass obtainable, in for high-quality test results. Composed primarily of silicone and oxygen, with trace amounts of boron and sodium, the expansion coefficient of this glass is approximately 33 × 10-7 ˚C. All of our clear glass vials are made using type 1, 33-expansion glass.

All batches of RSA-Pro X™ vials are tested for and have extremely low metal content, making them ideal for LCMS, LCMS/MS and GC/MS. Prevent spurious peaks from glass. The RSA-Pro X™ vial manufacturing process is conducted in an ultra-clean glass conversion facility without the use of any release agents, grease or glass additives.

HPLC Buffers. The selection of a buffer in terms of species, ionic strength and pH range is critical in reversed-phase chromatography.

Aug 01, 2007 · Five hundred nanograms of clotrimazole diluted in 200 μL acetone–ethyl acetate (1:1; v:v) was analysed via GC-MS using a glass vial and a plastic vial. 3. After 1 L of creek water had been spiked with 800 ng clotrimazole, the sample was allowed to equilibrate for 2 h and then filtered.

tolerances and UV and MS cleanliness tests required of the LC/GC and LCMS Certified Vials lines. The glass surface of TruView™ vials exhibits low polar analyte adsorption. TruView vials are manufactured under tightly controlled process conditions (patent pending) that limit the concentration of free ions on the surface of glass which

measured values obtained using the GC/MS method were lower than the target concentration as well as the values measured by FTIR. Figure 6 shows the agent concentrations measured by the RIR and GC/MS methods after the completion of the agent discharge in the fire tests. The GUMS results were lower than the FTIR values or the target concentrations.

Gas Chromatography Mass Spectrometry (GC/MS) Today's labs need and want more from their chromatography so many have turned to mass spectrometry for greater insights and precise data. We can help. Our mass spectrometry solutions are built around proven technology that is designed to meet your growing analytical lab requirements.
