Bis(4-acetylphenyl)methane
Supplier:
MilliporeSigma
Description:
Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol® solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS.

Description:
Clear and free from particulates. Suitable for use in organic synthesis and other anhydrous solvent applications.
Elbow adapter with septum cap (EM-692004-2) allows for the removal of solvent under nitrogen atmosphere. Replacement septum (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.

MilliporeSigma
Description:
SupraSolv® MS is dedicated for use in gas chromatography coupled with mass spectrometric detection. SupraSolv® solvents offer the largest specified retention time range, a clear baseline and a minimal signal-to-noise ratio leading to reliable and reproducible analysis results. This method is used e. g. for the analysis of dioxins and furans (PCDD/PCDF) in food and water samples or for the determination of PAH (polycyclic aromatic hydrocarbons) in food. Also commonly used in QuEChERS pesticide residue analysis.

MilliporeSigma
Description:
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.
