Dioxin Analysis

Solvents for Dioxin Analysis

Analysis of dioxins including coplanar PCBs is not easy because target compounds have many isomers and concentrations are extremely low. We offer optimized solvents and sample cleanup agents that do not interfere with the target compound in dioxin analysis.

Solvents for Analysis of Dioxins “Guaranteed by x10,000 Concentrated Solvent”

Blank test of solvent “Guaranteed by x 10,000 Concentrated Solvent” is conducted. Blank test of each solvent “Guaranteed by x 10,000 Concentrated Solvent” by GC/MS(SIM) shows that 4-8 chlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) are below 10μg/L(10ppb).

Residual Solvent Analysis

Residual Solvent Analysis

In the residual solvent analysis, the amount of organic solvent present in pharmaceuticals is determined by gas chromatography and it is confirmed that the organic solvent does not exist in the drug beyond the limit value. Our residual solvent analyzing reagent reduces the content of low boiling point impurities such as methanol and guarantees the quality by suitability for residual solvent analysis.
