Fisher Scientific offers a broad range of high quality deuterated products from the Acros Organics and Alfa Aesar brands for all your routine synthesis and structural analysis needs. These solvents contain high chemical purity and maximum isotopic enrichment. Deuterated solvents are manufactured for use with NMR instruments
Mar 19, 2015 · Additionally, size-exclusion high-performance liquid chromatography is completed prior to GC/MS analysis for further sample cleanup. Lastly, the GC/MS method is almost an hour long for each sample . All of these steps result in a low-throughput method.
Mar 29, 2014 · After exposure, we stored STs individually in screw‐cap 1.5 ml glass vials, prior to analysis by TD–GC–QMS; clear vials were used in the glasshouse and laboratory, and amber‐colored vials were used in the field to protect samples from high UV light intensity.

Gas Chromatography Solvents Spectrum carries a large variety of gas chromatography solvents which are high purity solvents specifically controlled for GLC techniques. These include methyl alcohol, also known as wood alcohol and methanol; hexane, used as non-polar solvent due to its relatively safe nature, and more.
screw-cap vials were used to contain the 6 g anhydrous MgSO 4 + 1.5 g NaCl for the method. Standard 1.8 mL dark glass auto sampler vials were used to contain the final extr acts. Reagent s (a) MeCN, methanol (MeOH), and water.—The organic solvents were of sufficient quality for pesticide residue analysis and were obtained from Labscan (Dublin
Fisher Scientific offers the vials you need for all of your laboratory requirements and applications. Whether your needs include chromatography, sample storage, cryo-preservation or scintillation, we have options for you.
Attached caps help maintain cleanliness. Wheaton™ Clear Glass Sample Vials in Lab File With Caps Attached come in partitioned trays to provide an easy way to store empty vials or to inventory samples.
Using the QuEChERS method, food/agricultural samples are first extracted with an aqueous miscible solvent (e.g., acetonitrile) in the presence of high amounts of salts (e.g., sodium chloride and magnesium sulfate) and/or buffering agents (e.g. citrate) to induce liquid phase separation and stabilize acid and base labile pesticides, respectively.
Glass and Plastic Vials Individuals that have never stepped foot in a laboratory can imagine what it’s like in a lab. Those individuals probably imagine work stations with test tubes and glass vials.
