basis and predicts properties related to the process that we are monitoring,” explains Francisco. “So, if we are looking for the composition of a polymer, the model could depict how to turn the Raman spectrum into the weight percentage of different monomers that comprise the polymer.” Selecting the advanced technology has
also resulted in significant cost savings. “Compared with the more expensive Raman system we used previously, our MarqMetrix All-in-One cost at least 50% less,” says Francisco. Te versatile Raman technology is
Raman system analysis is useful for the compositional analysis of reactants going into a chemical reaction
analysis applications that can be changed in seconds, without the need for recalibration. MarqMetrix manufactures a wide range of standard and custom probes to measure compounds in any form, including solids, liquids, gases, slurries, pastes, and gels. Traditionally, Raman spectroscopy
requires the accurate and precise ongoing focusing of the laser onto the sample by the operator for repeatable analysis, which can slow productivity and introduce human error. To streamline the process and increase reliability, MarqMetrix probes eliminate the need for the operator to focus the laser. Tis enables the user to simply touch the sample and get the same reproducible measurement every time with accuracy of +/- 0.1%. “Te probes are the only component that touches or interacts with the sample itself, so we have purchased ball, proximal, and flow cell probes to ensure we have all the options in our toolbox,” says Francisco. Te new Raman systems are designed to be quick and easy to use right out of the box. “When we received our system, we unpacked the box and were collecting Raman measurements within 10 to 15 minutes. I have never seen that before with a Raman system. Te level of simplicity and accessibility is unheard of

with this type of equipment,” comments Francisco.
Although the MarqMetrix Raman equipment can be used to identify the components within approximately 15 minutes of unboxing, quantifying the concentrations of each component first requires creating a predictive model. For general laboratory use, MarqMetrix offers a library of pre- developed models that covers most common applications. “In a manufacturing environment, [we use] a model that runs on a continuous
providing Chemours with the flexibility to measure and analyse polymers as needed, according to Francisco. “We have found that Raman is also a very nice standalone technique that complements everything else in the lab. It is not only a new technology for established applications, but also a flexible technology that finds its own niche in the laboratory,” concludes Francisco.
LOOKING AT THE BIGGER PICTURE Accurate measurement is more essential than ever in the polymer industry. Understanding the chemical composition of raw materials and the consistency of processed products is the key to manage processes, reduce risks and maximise outcomes. With the advancements in applying Raman spectroscopy systems to sample measurement, internal laboratories now have a reliable and economical tool that produces accurate, fast results and also complements existing testing methodologies.
BEFORE AND AFTER B
efore MarqMetrix, high- performance Raman systems were highly sensitive,
expensive and immobile scientific equipment, making them cost- prohibitive for broad commercial applications. With a small footprint, TouchRaman sampling, and lower cost, the MarqMetrix
All-in-One makes Raman measurement more accessible – putting decision-makers at the point of measurement. Using the company’s BallProbe with its All-In-One system increases the accuracy and speed of Raman measurements so that users can make more of them.
