TOC-L Series TOC-L Series has a The TOC-L series of TOC analyzers adopts the 680°C combustion catalytic oxidation method, which was advanced by Shimadzu and is now utilized worldwide. ?While providing an ultra wide range of 4 ?g/L to 30,000 mg/L, these analyzers boast a detection limit of 4 ?g/L through coordination with NDIR. Important Functions: - This is the highest level of detection sensitivity available with the combustion catalytic oxidation method. - Combustion catalytic oxidation method makes it possible to efficiently oxidize not only simplify-decomposed, low-molecular-weight organic compounds, but also hard-to-decompose insoluble and macromolecular organic compounds. - Extremely wide measurement range from 4 ?g/L to 30,000 mg/L, applicable to many things from ultrapure water to highly contaminated water ?TOC-LCSH/CPH? Capable of TC, IC, TOC , and NPOC measurement; options enable POC , TOC via POC + NPOC, and even TN measurements The blank check function evaluates system blanks by measuring ultrapure water processed.
