Shimadzu TOC-LCPH: a high-precision, versatile TOC analyser for demanding applications
The Shimadzu TOC-LCPH is a Total Organic Carbon analyser specially designed to meet the growing demands of water quality control, cleaning validation in the pharmaceutical industry and environmental analysis. Its main advantage lies in its 680°C catalytic oxidation method combined with NDIR (Non-Dispersive InfraRed) detection, ensuring high reliability even with the most stubborn organic compounds. This PC-controlled model is particularly suitable for intensive use thanks to its advanced software integration.
The TOC-LCPH configuration allows extremely accurate measurements over a wide range of concentrations from 4 µg/L to 30,000 mg/L. This makes it equally suitable for analysing ultrapure water and heavily loaded industrial effluents. It is capable of measuring TC (total carbon), IC (inorganic carbon), TOC (total organic carbon) via TC-IC subtraction, NPOC (non-purgeable organic carbon), and, optionally, TN (total nitrogen) and POC (volatile organic carbon).
The system is fully automated with syringe pump sampling, automatic acidification and degassing, automatic sample dilution up to a factor of 50, and intelligent out-of-range peak management. It offers excellent reproducibility, with a coefficient of variation (CV) of less than 1.5% for TOC and a detection limit of only 4 µg/L.
In addition, the TOC-LCPH can be combined with various optional modules such as the TNM-L for total nitrogen measurement or the SSM-5000A for direct analysis of solid samples. The ASI-L module allows automatic sampling of up to 93 vials, while the OCT-L offers simplified sampling of 8 to 16 samples without transfer.
Software integration via LabSolutions TOC provides a secure, 21 CFR Part 11-compliant environment with user management, data traceability and automatic report generation. Compatibility with text files (CSV), USB devices, standard printers and LAN networks completes the system's connectivity.
The TOC-LCPH features a compact design (20% narrower than previous models) and is energy efficient (up to 43% less power consumption), making it ideal for laboratories with limited space or concerned about their environmental footprint.
