2. Vial quality and cleanliness (especially for MS applications). See attached white paper that disusses the influence/role of vial quality in LCMS applcations. If you would like a little guidance/help in choosing the correct sample vial, please use this simple vial selector tool. I hope this information helps you make an informed decision.
Im doing HPLC to identify and quantify polyphenols in my sample. My question is I prepare 2 ml of my sample in the glass vial ready for HPLC analysis and the injection volume is 20 ul (microlitre

Oct 01, 2010 · 4.2 Synthesis of [18 F]xenon difluoride in pyrex glass or polypropylene vials. Anhydrous [18 F]F −-K +-K 2.2.2 solution (2–10 mCi) in acetonitrile (~300 μL) was prepared from cyclotron-produced [18 F]fluoride ion, potassium carbonate (3.6 μmol) and K 2.2.2 (11 μmol) and added to a clear pyrex glass vial (2.0 mL, Waters) containing xenon

The organic layer is decanted and placed into a 2 mL GC/LC sample vial. Depending on the detection scheme used and the desired reporting limits, a 2-10X concentration/dilution of the extract may be required to achieve the necessary sensitivity. Step 10: Preservation & Analysis
The carrier gas (helium) was set at a constant flow rate of 1.2 mL/min. Mass spectrometry employed an Aijiren 240 ion trap detector in selective ion storage mode with electron ionisation (EI). The GC method gave good linearity in the range of 10–500 µg/kg.
Waters has developed process handling protocols and QC procedures to ensure Waters Certified Vials meet their specified dimensions, levels of cleanlines, and adsorption properties. These rigorous 2-, 3-, and 4-step certification processes provide clean vials for the demands brought on by sensitive chromatography systems.
Insect species composition is an important phenomenon playing a significant role in the ecosystem. Chemical control of insects and pests releases toxic materials to the environment. These chemicals are dangerous to human populations. In this situation, there is a dire need to develop strategies to overcome the haphazard use of chemicals. The present investigations were carried out to explore

Vials and closures listed in this section are designed, engineered and manufactured for optimum performance with HPLC and LC/MS applications.
A great deal of energy, money, and time can be spent on sample preparation. The last thing you need is for a sample vial to contribute to contamination resulting in complicated data interpretation or complete reanalysis. By using certified
