Fisher Scientific Optima grade solvents meet extremely high purity (ppm) levels. They are manufactured for use when contaminant-free performance is essential, as in HPLC, GC, plasma/ICP, spectrophotometry, environmental testing, and other analytical applications.

Fisher Chemical Optima LC-MS solvents lead the industry with an unprecedented LC-UV gradient suitability specification. Each lot is screened for UV-absorbing contaminants at every wavelength in the 200–400 nm range to afford smooth baselines, reduced interferences, and increased confidence in your analyses.

UNICHROM products are specially made for high performance liquid chromatography. Our high purity solvents are tested to meet strict UV absorbance specifications as well as ion pairing reagents.

Fisher Scientific GC-Headspace solvents are performance tested to ensure the absence of trace level International Conference of Harmonization (ICH) residual solvents for accurate and repeatable determination of trace levels of Class 1, Class 2, and Class 3 residual solvents in pharmaceuticals.

To simplify your workflow, Thermo Scientific Dionex has developed all the reagents and standards you need, including anion and cation standards, eluent concentrates, and AutoRegen concentrates. Thermo Scientific Dionex offers high-purity chemicals and standards for transition metal analysis, including ultrapure chelation chromatography reagents for trace and ultratrace transition and lanthanide metal analysis.
