Process Refractometers Used in Industry

Process refractometers provide the analysis to quickly, reliably, and very accurately identify a sample and determine it's concentration and purity levels. They measure the refractive index and temperature of flowing liquids, and apply mathematical functions to determine the concentration of dissolved solids.

Part physics, part material science and part chemistry, refractometry is the process which measures the composition of known substances by means of calculating their respective refractive indexes (RI).  Light bends and changes velocity as it travels from one media into another through the media interface. When light traveling through air enters liquid, the light rays change direction by an amount determined by the liquid's density. RIs are evaluated via a refractometer, a device which measures the curve, or refraction. The
unitless number given by the refractometer, usually between 1.3000 and 1.7000, is the RI. The composition of substances is then determined when the RI is compared to a standard curve specific to the material of the substance. Standard tables are available that correlate RI to a variety of materials. These same tables also correlate RI to varying concentrations of particular liquid media at a particular temperature. Take corn syrup for example. Different refractive indexes are observed for different corn syrup samples of different concentrations. Therefore, by using a process refractometer to observe the RI of a particular corn syrup sample, a determination of the concentration of that particular sample can be made. By referring to the table or scale that correlates the RI to concentration at a particular fixed temperature, liquid concentration can be determined.

Common industrial refractometer applications are:

  • Calculating amount of sugar dissolved in juices and beverages.
  • In commercial food applications such as juice production or tomato processing, refractometers are used to measure degrees Brix (the Brix scale relates refractive index to sugar concentration, and is a key way to maintain consistency).
  • In the pharmaceutical industry, process refractometers are used to monitor and control concentration levels during supersaturation, a critical process in crystallization.
  • In pulp and paper production, process refractometers for measuring dissolved solids in black and green liquor during the chemical recovery process.

Equipment manufacturers have developed numerous refractometer configurations tailored to specific each use and application. Each has a set of features making it the advantageous choice for its intended application. Product specialists are invaluable sources of information and assistance to potential refractometer users seeking to match the best equipment to their application or process.

Process Refractometers for Food and Pharmaceutical Use

There are many industrial applications for process refractometers; particularly useful in the food and pharmaceutical industries, where there is a need for solids content measurement. Process refractometers are used to optimize production processes, ensure consistency and purity, and in managing quality control. Process refractometers and inline process refractometers, are types of refractometers designed for the continuous measurement of a fluid flowing through a pipe or inside a tank. They provide analysis to quickly, dependably, and to accurately identify a sample to determine its concentration and purity levels. By measuring the refractive index and temperature of flowing liquids, refractometers can then apply a mathematical function to determine the precise concentration of dissolved solids.

In commercial food applications such as jam or jelly production or the processing of soft drinks or wine, refractometers are used to measure degrees Brix. Bix is a graduated scale, used on a hydrometer, that indicates the weight of sugar per volume of solution at a given temperature. The Brix scale relates refractive index to sugar concentration, and is a method of maintaining consistency. For example, process refractometers are used for the concentration process of fruit juices. The concentration process is normally achieved by removing water through evaporation, and by measuring Brix, the evaporation process can be controlled and related to the desired juice concentration.

Process refractometers are also used in pharmaceutical processing where there is the need to monitor and control concentration levels during supersaturation, a critical process in crystallization. Crystallization is a critical element in the purification of solids in pharmaceutical production. The process refractometer guarantees precise monitoring and a high degree of measurement accuracy and reliability, towards the production of a pure product.
