1096 Results for: "HPLC Solvents"

Supplier: MilliporeSigma

Offering a high degree of UV transmittance, low particle count, low acidity and alkalinity, and low evaporation residue level, LiChrosolv® solvents are ideal for reproducible separations. They are produced from specially selected raw materials, and undergo a number of purification steps prior to final packaging. Since separations are normally carried out under gradient conditions in analytical HPLC, Merck Millipore offer solvents in ’gradient grade’ as well as ’isocratic grade’. This enables you to minimise the gradient effect of the solvent involved.

10-Acetyl-3,7-dihydroxyphenoxazine (ADHP), also called Amplex® Red and Ampliflu™ Red, is not only a sensitive and stable fluorogenic substrate for HRP but also an ultrasensitive probe for H2O2. In the presence of HRP and H2O2, ADHP generates highly fluorescent resorufin that has maximum absorption of 571 nm and maximum emission of 585 nm. Unlike other HRP substrates such as dihydrofluoresceins and dihydrorhodamines, the air-oxidation of ADHP is minimal. So far ADHP has been known as the most sensitive and stable fluorogenic probe for detecting HRP and H2O2. ADHP has been widely used to detect HRP in many immunoassays. On the other hand, Zhou, et al. have demonstrated that ADHP can be used to detect trace amount of H2O2. The ADHP-based H2O2 detection is at least one order of magnitude more sensitive than the commonly used scopoletin assay for H2O2. Because H2O2 is produced in many enzymatic redox reactions, ADHP can be used in coupled enzymatic reactions to detect the activity of many oxidases and/or related enzymes/substrates or cofactors such as glucose, acetylcholine and cholesterol, L-glutamate, amino acids, etc. We offer the best quality of ADHP with the most competitive price. The reagent can be purchased in a single 25 mg vial or can be custom-packaged to meet your special requirements.

It is known that phenol and p-cresol are promoters of skin tumors and also urinary excretion of phenol and p-cresol is increased by exposure to benzene, which has hemopoietic toxicity, and toluene, respectively. Therefore, the determination of phenol and p-cresol is important in clinical chemistry and toxicology. Because phenol and p-cresol are present in urine as sulfate or glucuronide conjugates, they are hydrolyzed enzymatically or with acid, followed by distillation or extraction with organic solvent prior to measurement by GC or HPLC. However, these GC and HPLC methods require relatively large sample volumes (more than 1 ml) because of their insufficient sensitivities for measuring small amounts of phenol and p-cresol. The application of fluorescent labeling techniques to HPLC result in a sensitive and selective method. Phthalimidylbenzenesulfonyl chlorides habe also been successfully used for high sensitivity labelling of amino acids prior to HPLC.

1,1,1,3,3,3-Hexafluoro-2-propanol is polar and exhibits strong hydrogen bonding properties enabling it to dissolve substances that serve as hydrogen-bond acceptors. 1,1,1,3,3,3-Hexafluoro-2-propanol is a polar solvent of high ionizing power and facilitates Friedel–Crafts-type reactions, using covalent reagents in the absence of a Lewis acid catalys. 1,1,1,3,3,3-Hexafluoro-2-propanol clusters catalyzes the epoxidation of cyclooctene and 1-octene with hydrogen peroxide.
It is a speciality solvent effective for solubilizing a wide range of polymers, including those that are not soluble in the most common organic solvents: such as polyamides, polyacrylonitriles, polyacetals, polyesters (e.g. polyglycolide), and polyketones. It has also found use in biochemistry to solubilize peptides and to monomerize β-sheet protein aggregates. It can be used as an acid in volatile buffers for ion pair HPLC - mass spectrometry of nucleic acids. 1,1,1,3,3,3-Hexafluoro-2-propanol was used for preparing hexafluoroalcohol-functionalized methacrylate polymers for lithographic/nanopatterning materials.
