At-line batch TOC measurement can only provide snapshots of your water quality every six minutes or more. But alot can happen in six minutes. With true continuous TOC analysis you have real-time data to tell you exactly when an excursion starts and ends. This helps demonstrate compliance and gives you complete control of your water system. The Mettler-Toledo6000TOCi provides real-time TOC compliance.

Swissfluid SIV Series are inline, fully lined or stainless steel sampling valves for safe and representative sampling of corrosive and aggressive process media from pipelines, pressurized or under vacuum. SIV Sampling Valves are available as wafer-style or flanged valves. The valves are distinguished by its deadspace-free design as well as the extremely short outlet way for the representative sample. The sturdy bodies are made of stainless steel casting 1.4408 (CF-8M) or optional with resistant linings
Gaseous samples can be provided by means of the Piston Injector. This video demonstrates how the Piston Injector is used.

The METTLER TOLEDO Process Analytics division concentrates on analytical measurement solutions for industrial manufacturing processes. The division consists of two business units: Ingold and Thornton, both recognized leaders in their respective markets and technologies.
Ingold is a worldwide leader in pH, dissolved oxygen, CO2, conductivity and turbidity solutions for process analytical measurement systems
in chemical, food & beverage, biotech- nology and pharmaceutical industries. Its core competence is high quality in-line measurement of these para- meters in demanding chemical process and hygienic and sterile applications.
Thornton is the leader in pure and ultrapure water monitoring instrumentation used in semiconductor, microelectronics, power generation, pharmaceutical, and biotech applications. Its core competence is the in-line measurement of conductivity, resistivity, TOC, bioburden, dissolved oxygen and ozone in determining and controlling water purity. The division recently expanded into Gas Analytics with a series of TDL analyzers offering unique in situ solutions.
The 6000TOCi is a new, continuous measurement, TOC (total organic
carbon) sensor manufactured by METTLER TOLDEDO Thornton. The sensor provides
continuous, real-time measurements in pure and ultrapure waters. It uses
advanced UV oxidation technology that provides a very rapid response time.
Total Organic Carbon monitoring is vital for the measurement and control of organics contamination in pure and ultrapure waters used in industries such as pharmaceuticals, microelectronics and power generation.
To ensure changes in TOC levels are not missed, constant results are required. The 6000TOCi sensor uses conductivity measurements before and after oxidation of organic material via ultraviolet light to provide continuous, real-time determination of TOC.
Flexibility of the 6000TOCi allows installation anywhere on a water system, with the option to display results at the point of measurement or at a more convenient location for operators.
The METTLER TOLDEDO Thornton 6000TOCi Total Organic Carbon sensor has a response time of less than one minute and provides continuous monitoring, which is a huge advantage over batch measurement systems that take six minutes or longer to deliver just a snapshot of water quality.
This pencil appears to bend when it enters the water because of the change in the light ray speed as the medium changes.
Refraction is the directional change of wave propagation caused by a change in the light beams transmission medium.
Light rays travel through space in a straight line at approximately 300,000 km/s. As light passes through a transparent medium, such as water or glass, its speed is decreased.
For glass, its reduced to 200,000 kilometers per second, and for water the speed is 225,000 kilometers per second.
If the light enters into a medium perpendicular to the surface, it passes straight through but at a slower speed. However if the light beam arrives at the medium surface at an angle, not only will it speed be reduced, but it will bend due to a process called refraction.
As a beam of light reaches the surface of a medium the lower portion enters first and is slow down. However, the upper portion is still traveling at the speed of light until it arrives at the surface and enters. This speed difference at the top and bottom aspects of the light path causes it to pivot, bending toward what is referred to as the normal. This is an imaginary line drawn perpendicularly to the surface of the material.
Transparent materials have what is called a refractive index. This is the speed at which light travels in a medium compared to like traveling in a vacuum.
For example, typical glass has a refractive index of 1.33. This is calculated by dividing the speed of light in a vacuum (300,000 km/s) by the speed of light in glass (225,000 km/s).
The refractive index of air is 1.0003. Anytime a light beam travels from a medium with a low index of refraction, like air, to a medium with a higher index of refraction, like glass, the beam of light will bend toward the normal.
Likewise when the beam of light exits a highly refractive medium into a medium with the low index of refraction, the process is reversed.
The bottom portion of the beam of light exits first, and resumes at the speed of light, with the top portion still at the speed determined by the medium. This causes the beam to pivot away from the normal line.
Instruments used to measure the refractive index are called refractometers. Refractometers used in industrial automated systems are referred to as inline refractometers.
