HPLC solvents
HPLC solvents are controlled to meet high quality requirements of successful HPLC separations:Low UV-absorbance, assuring optimum sensitivity, Low content of non-volatile components like water, free acid and free alkali, Low particulates, pre-filtration is not necessary.

Solvents for GC residue analysis
Solvents for GC residue analysis were developed especially for the application in residue analysis of pesticides and other low-volatile, environmentally relevant substances by means of GC/ECD or GC/PND, organochlorinated pesticides, dioxin, furan, PCBs and so on.
General products: Acetonitrile, Methanol, Acetone, tert-Butyl Methyl ether, Cyclohexane, Dichloromethane, N,N-Dimethylformamide, Ethyl acetate, n-Heptane, n-Hexane 95%, iso-Octane, n-Pentane, 2-Propanol, Petroleum Ether 40-60°C, Toluene, Trichloromethane.
GR grade reagents
GR grade reagents are generally used for analytical laboratory work. Moreover, these reagents are also usually used in the productive field. The quality of these reagents is strictly controlled, with high major components, and low impurities. Each reagent has its own certificate of analysis (COA) and individual expiration date.
General products: Acetic acid glacial, Carbon disulfide, Diethyl ether, Formic acid, Hydrochloric acid, Nitric acid, Sulfuric acid. |
