■Report creation tool, capable of outputting items required by EU regulations
Reports of the analysis of dioxins in foods must contain the results of complicated calculations. A report creation tool is included in this product. It can
automatically create reports showing items required by EU regulations. Additionally, it is capable of combining reports on DXNs and PCBs, changing the Point
items displayed, and showing the Limit of Quanti cation (LOQ) calculation method, providing support to varied customer analyses. 2
