Continuous, Real-time Measurement for Full Visibility of Total Organic Carbon (TOC) in Pure and Ultra-Pure Water Systems

At-line batch method of monitoring total organic carbon (TOC), which takes measurements at set intervals, is the equivalent of taking snapshots of information. The gaps between measurement intervals could easily miss a critical event, whereas on-line, continuous TOC monitoring done by the Mettler Toledo 6000TOCi total organic carbon analyzer captures any-and-all excursions in real-time.

Monitoring total organic carbon levels is critical to meeting internal water quality specifications and global pharmacopeia regulatory requirements. Missing an increase in TOC levels can put you at risk of contaminating your water system, which in turn could affect production and potentially lead to an out-of-spec event or product recall.

Most TOC analyzers on the market offer at-line batch or non-continuous methods of total organic carbon measurement, which limits TOC data collection to every 6-12 minutes. But much can happen in six minutes.  When you are subject to an audit or have a quality problem, how are you sure that you did not experience a problematic TOC excursion between batch samples?

The 6000TOCi analyzer’s true continuous measurement along with its comprehensive record keeping and advanced diagnostics provide audit-ready TOC compliance and complete control of your water system.

Validating Water Cycle pH Requirements Using Conductivity and Calculated pH


In thermal power plants, pH measurement and control in the water steam cycle are critical to minimizing corrosion. Cycle chemistry guidelines specifically target narrow pH ranges.

However, in high purity water and steam, there are not enough ions in the water to generate a pH response, causing the pH reading to be unstable. Fortunately, conductivity has a direct relationship with pH when the sample contains only pure water with the typical alkaline treatments, such as ammonia and amines. In fact, cycle chemistry in many plants relies primarily on the related specific conductivity values. However, correction for minor contaminants by measuring the cation conductivity of the sample is needed to provide accurate results. The specific and the cation conductivity values are used in an industry accepted calculation that provides the highest accurate conversion to pH. Under normal operating conditions, this calculation provides more accurate and reliable results than pH electrodes can provide, for two reasons:
  1. Conductivity is linear, with concentration which provides much higher resolution than pH sensors all of which give nonlinear response to concentration.
  2. Conductivity sensors can be directly calibrated with minimal introduction of error. 
All pH reference electrodes have a variable junction or diaphragm potential that can change between buffer calibration and process measurement, introducing some uncertainty to subsequent measurements.

This makes calculated pH based on conductivity significantly more accurate. However, with major contamination, such as when a condensate exchange polisher's resin is exhausted, and an acid leak occurs, the pH would drop below 7, which is outside the ideal range for using calculated pH and would generate errors. Thus, to avoid contamination, it is recommended that both traditional pH measurement, and calculated pH based on conductivity, be used for optimal pH control.

METTLER TOLEDO Thornton's M800 multi-parameter transmitter can provide traditional pH measurement, calculated pH, as well as specific and cation conductivity to ensure accurate and reliable pH control. The M800 even has a built-in alarm to alert you if the pH measurement deviates from the calculated pH measurement for extra security and peace of mind.

The Mettler Toledo GPro® 500 Series of Tunable Diode Lasers

Tunable Diode Lasers


Tunable Diode Lasers (TDLs) use a measurement technology called absorption spectroscopy: they output a beam of laser light at the same frequency that the gas to be measured absorbs light. The TDL analyzes the light after it has passed through the gas stream and calculates the quantity of the target gas in the stream. The use of TDL sensors is becoming more and more common in industrial processes.

Mettler Toledo manufactures the GPro® 500 TDL Series of Tunable Diode Laser designed for the toughest gas measurements. These analyzers are known to handle some of the most demanding process applications, particularly where accuracy and fast response is crucial.

Using a modular design, the GPro® 500 tunable diode laser gas analyzer allows you to select the process adaption that fits your application, and match it with the parameter that you need to measure. We offer sensors that measure  a variety of gases including Carbon Dioxide (CO₂), Carbon Monoxide (CO), Hydrogen Chloride (HCl), Hydrogen Sulfide (H₂S), Moisture, Ammonia (NH₃), Methane (CH₄) and Oxygen (O₂).

GPro® 500 Tunable Diode Laser - Eliminate Alignment

Most TDLs are comprised of two parts: the laser source unit and a receiving/analyzing unit. These parts must be installed directly opposite each other, which is not always easy and misaligned can often occur. METTLER TOLEDO's GPro® 500 Series solves this by combining both parts in a single unit. A probe attached to the GPro® sensor protrudes into the gas stream. A three-sided mirror at the end of the probe directs the beam back through the probe to the receiver, so alignment is always perfect.

GPro® 500 Tunable Diode Laser - Minimal Maintenance

GPro® 500The GPro® does not require "maintenance intensive" extractive and conditioning systems. This means that you receive consistent performance from your tunable diode laser gas analyzer without the downtime and cost associated with these traditional systems. You achieve reliable uptime, critical in safety applications, at a reduced cost of ownership.

Inline Dissolved Oxygen Sensor Designed for Breweries

InPro6970i for brewing
InPro6970i for brewing
Oxygen in beer bottles or cans is bad. It affects the flavor and shortens shelf life, so breweries do their best to prevent oxygen getting into beer  at the filling line.  The Mettler Toledo Process Analytics InPro6970i is an inline dissolved oxygen sensor designed specifically for the needs of the brewery industry. It can measure oxygen in beer at levels of only a few parts per billion.

The sensor is inserted in the pipe at the start of the filling line, and provides real-time measurements on the oxygen content of the beer.  If the oxygen level is too high, the flow of beer is stopped to prevent the out of specification product continuing down the line.

Unlike most dissolved oxygen sensors available, the InPro6970i uses a clever optical technique for measuring oxygen. At the tip of the sensor there's a layer of molecules that absorb and emit light. These molecules are sensitive to oxygen which alters how the molecules behave. The greater the quantity of oxygen, the greater the changes in their behavior. The sensor very accurately measures these changes and sends the signal to the transmitter.  This technique is extremely fast and accurate at measuring changes in beer oxygen level, which is why it is favored by breweries. But that is not the only requirement breweries demand.  Sensors must be rugged, easy to use, and simple to maintain.The InPro6970i scores highly in all these areas. The sensor's stainless steel body is extremely robust, the unit is easily and quickly installed, and the only maintenance required is the periodic exchange of the oxygen sensitive element, the OptoCap. Intelligent Sensor Management, or ISM, is a feature of the InPro6970i that offers significant benefits to breweries. The sensor can be calibrated in a convenient location such as a lab. Upon connection to the transmitter, the system is ready to measure in only a few seconds, so measurement point down time is very short. The dynamic lifetime indicator uses sophisticated algorithms to calculate the remaining life of the sensor, breweries therefore have confidence that the sensor won't fail unexpectedly.

A Better Way to Measure Dissolved Oxygen in Power Plant Pure Water Systems

measuring dissolved oxygen
In power plants, approximately half of unscheduled shutdowns can be traced to water cycle chemistry issues which involve costly repairs and lost operating revenue that can never be recovered. One of the most important parameters to measure to improve power plant water system efficiency is dissolved oxygen, DO. DO causes corrosion of components that contain iron and copper. Transport and deposits of these particles can also accelerate corrosion and damage critical plant equipment.

DO is measured at several locations in a water system. Traditionally, DO is measured with polarographic sensors, which use a gas permeable membrane to separate the sample from the electrochemical cell inside. Depending on the operating environment, polarographic sensors can require monthly electrolyte and membrane replacement.  After service, the sensor cannot produce meaningful readings for several hours because of required polarization. They are also sensitive to sample flow rate and experience interference from dissolved hydrogen.

pure water optical DO sensor
Mettler Toledo pure water optical DO sensor 
Unlike traditional DO sensors, the Mettler Toledo Thornton online pure water optical DO sensor does not require polarization. It uses optical technology to provide fast and accurate analysis. Its measurement response is six times faster than polarographic sensors. The optical DO sensor also does not use electrolyte or a membrane, so it's not sensitive to flow or susceptible to damage from particles and dissolved hydrogen interference. There is no interior body to replace, and service is required only once a year to quickly and easily replace the one-piece Optocap sensing element. This provides plants with lower operating costs and reduced downtime. 

The Mettler Toledo Thornton pure water optical DO sensor provides a fast, accurate and low-maintenance method of measuring dissolved oxygen concentration in power plant pure water systems.
