METTLER TOLEDO Thornton 5000TOCi sensor with Intelligent Sensor Management™ (ISM) provides continuous, fast, and reliable monitoring of total organic carbon (TOC) levels in applications such as Water for Injection, reverse osmosis membranes, effectiveness of TOC destruct UV lamps, resin bed performance, organics shedding, and quality of final rinse water. The 5000TOCi sensor uses proven ultraviolet (UV) oxidation with differential conductivity to effectively determine TOC concentrations. The sensor meets pharmaceutical requirements USP <643>, <645> and EP 2.2.44 as well as for semiconductor ultrapure water monitoring.

The Thornton 5000TOCi sensor with M800 multi-parameter transmitter provides a user-friendly and economical analytical package. The M800 transmitter is available in two- or four-channel versions. The two-channel version can accept one or two TOC sensors, or TOC plus one other parameter. The four-channel version can accept up to three parameters in addition to TOC, including conductivity, pH, ORP, dissolved ozone or dissolved oxygen, plus two pulsed flow sensors.

The versatile usage of the 5000TOCi Sensor with ISM

In microelectronics pure and ultrapure waters

• The 5000TOCi Sensor and M800 multi-parameter transmitter provide measurements of all key parameters in a practical package.
• To alarm and enable correction of abnormal conditions, TOC can be monitored at all critical pure and ultrapure water treatment stages.
• To precisely follow pure water reclaim limits for TOC and resistivity, and provide the fastest possible response.
• Lowest detection level to meet sub-ppb measurement demands.

In pharmaceutical water monitoring

• Full compliance with USP <643> and EP 2.2.44 TOC and USP <645> conductivity requirements.
• Drastically reduces record keeping for release of water through simplified data collection with innovative Peak and Average TOC measurements
• Improves the quality and reliability of calibration and System Suitability Testing (SST) with a semi-automated process which ensures consistent results.
• Continuous measurement to monitor any system upsets in support of Process Analytical Technology (PAT) initiatives.
• The standard for global pharmaceutical requirements is assured by THORNTON instruments.

In power generation makeup water treatment

• To alarm and prevent organics from entering the steam cycle, the 5000TOCi with the M800 transmitter can provide continuous TOC monitoring, especially important where non-conductive organic halides could pass through the treatment system undetected by conductivity.
• The M800 multi-parameter transmitter is used for other parameters measured in both makeup and cycle chemistry, such as pH, ORP, dissolved oxygen, pH calculated from specific and cation conductivity and CO2 calculated from cation conductivity and degassed cation conductivity.
