821 Results for: "GC SOLVENTS"

Supplier: MilliporeSigma

Suitable for use in organic synthesis and other anhydrous solvent applications. Clear liquid is filtered through a 0.2µm filter, making it free from particulates. Flammable and toxic.
Elbow adapter with septum cap (EM-692004-2) allows for the removal of solvent under nitrogen atmosphere. Replacement septa (EM-692004S-2), for use with elbow adapter, minimizes air and moisture intrusion once the primary septum is punctured. Drying tube (EM-692010-2) filled with t.h.e.* desiccant indicating silica gel removes solvent under a dry-air atmosphere. Large plug (EM-692012-2) is a replacement plug for bottle top.

Building block for synthesis. Frequently used as precursors to di-tert-butylcyclopentadienyl (Cpt) ligand in many sandwich and half sandwich complexes. Di-tert-butylcyclopentadiene reacts with excess potassium tert-butoxide in the presence of elemental selenium to yield cyclopentadienes bridged by two or three selenium atoms through one or two diselenoketal functionalities. It reacts with excess potassium tert-butoxide in the presence of elemental sulfur to yield cyclopentadienes bridged by sulfur atoms via one or two dithioketal functionalities.

Hexane (C₆H₁₄) is a flammable colorless liquid; it has a faint odor and is highly volatile. It is a chief constituent of petroleum, petroleum ether and gasoline. It is used as a solvent for adhesives, vegetable oils and to extract oil and grease contaminants from water and soil for analysis. Hexanes are commonly used in chromatography as a non-polar solvent. Suitable for GC and Pesticide Residue Analysis.

EPA method 8330 is used to measure explosives residues in water and soil samples, using HPLC with UV detection. Target analytes are nitroaromatic and nitramine explosives and their degradation products. Obtaining pure, neat compounds for Method 8330 reference standards can be very difficult. To ensure the highest quality standards, Restek's Quality Control (QC) lab confirms the identity and purity of mixture components and solvents using one or more of the following techniques: GC-FID, HPLC, GC-ECD, GC-MS, LC-MS, refractive index, and melting point.
