Analyzing dioxins, including coplanar PCBs, is a complex process due to the presence of multiple isomers and their extremely low concentrations in environmental samples. To support accurate and reliable results, KANTO offers high-purity solvents and specialized sample cleanup agents that are carefully optimized not to interfere with the target compounds in dioxin analysis.
Our “Guaranteed by x10,000 Concentrated Solvent” series undergoes rigorous blank testing to ensure minimal contamination. These solvents are tested using GC/MS (SIM mode), confirming that levels of 4-8 chlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) are maintained below 10 µg/L (10 ppb) in concentrated form. This translates to less than 1 ng/L (1 ppt) in the original product, ensuring extremely low background levels suitable for trace dioxin analysis.
These high-performance solvents are ideal for laboratories conducting high-sensitivity dioxin analysis in environmental monitoring, food safety testing, and regulatory compliance.

In pharmaceutical testing, residual solvent analysis is essential to ensure that organic solvents used during manufacturing are within acceptable limits. This analysis is typically performed using gas chromatography (GC) to detect and quantify any remaining solvents in the final product.
Our residual solvent analysis reagents are specifically formulated to support this process by minimizing low-boiling-point impurities such as methanol. Each reagent is quality-assured for suitability in residual solvent testing, ensuring precise, reliable results and compliance with regulatory standards.
