Inline Process Refractometers for the Pharmaceutical and Food Processing Industries

When it comes to easily, reliably and accurately determining the concentration, identification or purity of substances, refractometry is the ideal method. Inline process refractometers are especially helpful as they supplement laboratory research and contribute to production improvement. These process analyzers deliver results within fractions of a second, allowing real-time monitoring and automatic control of processes.


Electron Machine Corporation's MPR E-Scan™ inline refractometers provide process analysis and control of liquid and slurry process streams in pharmaceutical and food processing applications. The MPR E-Scan™ provides accurate control and precise monitoring of variables in process streams, including percent concentration, solids dissolution, and solution reduction. The inline process refractometer also excels in measuring and managing crystallization, verifying and regulating the correct mix of various compounds, and determining the sugar concentration in a wide variety of products. In addition, the MPR E-Scan™ is often used to track concentrations in evaporation processes.

The MPR E-Scan™ is available in a broad range of models to accomodate a wide variety of measurement ranges and resolutions, providing users an abundance of choices to fit the right equipment to the right application.

Designed with ruggedness and durability in mind, the IP65 / NEMA 4X rated MPR E-Scan™ will withstand the rigors of CIP (Clean-in-Place), allowing the inline process refractometer to be thoroughly and meticulously cleaned at any time in a process environment. Each process refractometer is designed and manufactured specifically for each application, assuring trouble-free service with a minimum amount of maintenance for years to come.

The operation of the MPR E-Scan™ inline process refractometer is based upon the principle of light reflection. Light radiated from the LED passes through the prism surface to be reflected from a mirror to the prism-to-process interface. The light reaching this interface intersects the same interface over a series of angles chosen to include critical angle for the process being measured. Light intersecting the interface at an angle greater than critical angle is refracted into the solution. Light intersecting the interface at less than critical angle is reflected up to a second mirror and out of the prism up to the CCD linear array to be scanned.

In short, the MPR E-Scan™ inline process refractometer makes process metrics more visible to the user and significantly reduces product quality fluctuations. This increases efficiency, lowers production costs, and increases process reliability.  The MPR E-Scan™ can be applied to a wide range of applications in the pharmaceutical and food industries, thanks to their field-proven and reliable technology.

New! 24 Volt, DC-DC Option for the DCR E-Scan and MPR E-Scan In-line Process Refractometers

Electron Machine Corporation announced June 2, 2020 that the new 24v DC-DC Power Supply has been officially released for use in the DCR E-Scan and MPR E-Scan models.

“This is the successful culmination of many hours work and several revisions,” says Jack Wilburn, Operations Manager for Electron Machine, “and provides us the ability to satisfy the needs of many clients who seek a mobile solution for in-line process measurement of Refractive Index.” 

Reading Milk Fat content, de-icing solutions, and the measurement of sugars on harvesting equipment are just a few of the applications this new power supply address. Static operations that benefit from this advancement are solar operated locations as well as areas that lack high voltage AC service. This new option provides a solution for these low power areas.

Inline Process Refractometers for Measurement and Control of Sulfuric Acid Concentration in Industrial Applications

Sulfuric Acid (Sulphuric Acid, H2SO4) is a widely used commodity chemical. Because of it's corrosive properties, special attention has to be paid to its handling and storage. Measuring the concentration of Sulfuric Acid (sometimes referred to as Concentration Density of Sulfuric Acid) is a critical part of the production process. Controlling H2SO4 concentration is very important in many industrial applications including the production of fertilizers, oil refinement, chemical processing, mineral processing and wastewater treatment. Maintaining the desired Sulfuric Acid concentration density ensures it's safe handling and ultimately affects product quality. Industrial inline process refractometers provide the best solution for determining and maintaining Sulfuric Acid concentration.

Electron Machine has a white paper that provides more detail on controlling Sulfuric Acid concentration. You can read and download the white paper here.

Successful, Long-term EMC and Florida Food Products Partnership Maintains Consistent, High Quality Production

Florida Food Products, innovator and leader in clean-label, natural food processing, and Electron Machine; a winning team.

Electron Machine Corporation and Florida Food Products have had a long and successful relationship with each other. In fact, Florida Food Products was one of the first food companies Electron Machine Corporation ever placed a rugged, in-line, process refractometer into operation; the year was 1956.

Located just a few miles from each other, the relationship was a natural.  Recently, Florida Food Products underwent a large expansion, requiring additional instrumentation from Electron Machine Corporation.  The first of these new generation in-line process refractometers was installed this past summer, and immediately paid dividends.  Upon installation concerning a test batch, the process refractometer read the material at a lower percentage of BRIX than anticipated by the engineers starting the line.  The staff at Florida Food Products made the appropriate changes to the concentration and the refractometer was deemed a great success.  Since this time, another unit has been purchased by the Florida Foods Team.

Electron Machine Corporation salutes the long relationship we have had with the Florida Food Products Team and looks forward to servicing this valued client for many years to come.
