2-Propanol ≥99.9%, CHROMASOLV™ for LC-MS, Riedel-de Haën™

Supplier: Honeywell Research Chemicals

2-Propanol (Isopropyl alcohol, Isopropanol, IPA) is a colorless solvent and is the simplest example of a secondary alcohol. It is moderately polar and has a boiling point of 82 °C. 2-Propanol dissolves a wide range of non-polar compounds and it evaporates quickly. Thus, it is used widely as a cleaning fluid, especially for dissolving oils. Suitable for LC-MS and cleaning LC-MS systems.

Acetone ≥99.8%, SupraSolv® for GC-MS, distilled, Supelco®

Supplier: MilliporeSigma

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.

2-Propanol ≥99.9%, CHROMASOLV™ Plus for HPLC, Riedel-de Haën™

Supplier: Honeywell Research Chemicals

2-Propanol (Isopropyl alcohol, Isopropanol, IPA) is a colorless solvent and is the simplest example of a secondary alcohol. It is moderately polar and has a boiling point of 82 °C. 2-Propanol dissolves a wide range of non-polar compounds and evaporates quickly. Thus, it is used widely as a cleaning fluid, especially for dissolving oils. Suitable for HPLC , spectrophotometry, GC and residue analysis.

Ethyl acetate ≥99.9%, CHROMASOLV™ for pesticide residue analysis, Riedel-de Haën™

Supplier: Honeywell Research Chemicals

Ethyl Acetate is an organic solvent with the structure CH₃-COO-CH₂-CH₃ (C₄H₈O₂). This colorless liquid has a characteristic sweet odor. In the laboratory, mixtures containing ethyl acetate are used in column chromatography and extractions. Ethyl acetate does not work well as a reaction solvent because it is prone to hydrolysis and transesterification. Ethyl acetate is volatile at room temperature and has a boiling point of 77 °C. Suitable for GC and Pesticide Residue Analysis.

Acetone ≥99.9% (dried basis), GC2™ for gas chromatography, for pesticide residue analysis, Burdick & Jackson™

Supplier: Honeywell Research Chemicals

B&J GC2 Solvents are developed for trace analysis at or below the part-per-billion level, using capillary gas chromatography. Each lot is performance tested to meet demanding GC specifications.

Samples of every B&J GC2 solvent are concentrated 1000-fold and tested by temperature-programmed capillary GC-FID. This analysis detects both low-boiling and high-boiling molecules, anything eluting from toluene through diesel fuel and other semi-volatile compounds of environmental interest.

Features:
Less than 1 ppb trace contamination for semi-volatiles with a molecular weight greater than toluene (92).
Ideal for EPA protocols
Actual lot chromatograms available upon request

Electron capture GC: No residue peaks greater than two ng/L as lindane.

Flame ionization GC: No peaks greater than one ng/mL, having a retention time of greater than diacetone alcohol, on a crossbonded 5% diphenyl/95% dimethyl polysiloxane capillary column for a splitless injection of a 1000-fold sample concentrate after exchange into hexane.

Methanol ≥99.90%, CHROMASOLV™ for LC-MS, Riedel-de Haën™

Supplier: Honeywell Research Chemicals

Methanol (CH₃OH) is also known as Methyl Alcohol or wood alcohol. It is a clear, colorless, volatile and flammable liquid. Methanol is a common laboratory solvent and is especially useful for HPLC, UV/VIS spectroscopy, due to its low UV cutoff. Methanol is toxic if ingested and can result in blindness, coma and death. Suitable for LC-MS applications and spectrophotometry.

Ethanol ≥99.9% (by GC), LiChrosolv®, gradient grade for liquid chromatography, Supelco®

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.
