Refractometry is a widely employed analytical technique used to indirectly measure dissolved solids content of subject liquids. The process employs a refractometer, a device or instrument, to determine the refractive index for a test sample. The measurement is employed throughout science and industry to assess a material's composition or purity.

The refractive index of a substance is dependent, in part, upon temperature and the wavelength of light used in the measurement. Common applications include Brix testing for sucrose level, along with others in the beverage, pulp and paper, chemical, flavor, and fragrance industries. Refractometry is used as a quality control measurement, to assure uniformity among product batches.

Manual refractometers have been available for many years and require human observation and interpretation of a scale reading to obtain a refractive index. Automatic, as well as in-line units are available today that provide uniform accuracy and faster sample processing.

The DSA E-Scan, manufactured by Electron Machine, is an automatic, bench-top critical angle refractometer with a digital readout and temperature-controlled sample chamber. Its compact size and rugged design permit operation in the field and in areas with limited space. The unit provides fast and accurate refractive index measurements of sample liquids.

Freeze Protection for All Sorts of Commercial and Industrial Things

Freeze protection requirements are ubiquitous and take many
forms. Each has a best solution employing a specialized heater.

Keeping process or inventory liquids from freezing, or becoming extremely viscous, can be an important part of any commercial or industrial operation. Freeze damage to equipment, piping, or containers can result in a wide array of consequences, all of them likely to be negative.

Developing an overall plan for freeze protection can be advantageous to attacking each application on an independent basis.

• Having a common vendor for all freeze protection equipment and supplies can help designers develop a knowledge base about how to meet application challenges with specific products, speeding implementation time. Service techs become familiar with applied products and methods, building their skills and efficiency at installing and maintaining applications throughout the facility.
• Identify all locations where freeze protection is needed. Develop a baseline of the methods employed and equipment installed to meet the needs of each location. Good records form the basis for good maintenance and the ability to make decisions regarding the operation and performance of each system.
• When selecting the products or methods to employ for freeze protection, consider the environment in which the hardware will be installed. Will it require protection from physical damage, chemical attack, or extreme weather. Is the installation space considered a hazardous zone, requiring special certifications for the heating equipment?
• The availability and control of applied heat can also be important. Is there a need for the heating system to deliver highly variable amounts of heat across the range of possible operating scenarios, in order to avoid overheating the process or stored materials? How quickly will the system need to ramp up to the desired operating temperature or respond to changes in an operating process?

These questions, and probably others specifically related to your application, should be part of the consideration for freeze protection applications. Enlisting the cooperation of a process heat specialist can apply leverage to your own process knowledge and experience to develop an effective solution to each challenge.

Drum Heater Applications

It is common for bulk liquids to be delivered, contained, or dispensed from large pails or drums. At various times and locations during its dwell time in a drum, inventoried liquids might need protection from freezing, or maintenance of an elevated temperature for viscosity control or another reason. It can be impractical to provide a controlled environment in which to house one or more drums, pails, or other containers. A specialized heater provides an effective and economical solution that is easy to put in place as needed.

Silicone rubber drum heaters require only electric power from an extension cord to deliver controlled heat to plastic or metal drums. They can be put in place in minutes and operate unattended to provide controlled levels of heat through the container walls to the target liquid. The units are rugged and have a self-contained thermostat. Various sizes and capacities accommodate a broad range of industrial applications. Specialized custom units can be configured for specific applications.

The short video shows the ease with which these drum heaters can be applied. Share your liquid processing and analytical challenges with fluid processing specialists, leveraging your own knowledge and experience with their product application expertise to develop effective solutions.

TOC Measurement in Water Systems

Total Organic Carbon, referred to as TOC, is a measurement providing one of several facets to indicate the purity of a water sample or stream. Organic contamination in water for use in power generation, semiconductor manufacturing, and pharmaceutical production poses a number of operational risks or quality failures that can substantially impact process output. The elevated presence of carbon compounds in certain purified water sources can be an indicator that water treatment processes are not performing properly and need attention.

The measurement technology involves oxidation of carbon compounds in the presence of UV light and measuring sample conductivity. Processing of the raw measurement yields a value for TOC. Analytical instruments benefit from having features and attributes that lessen the need for human involvement and deliver rapid and accurate results. Mettler Toledo provides an advanced solution for TOC measurement with it 5000TOCi analyzer.
