Process analyzer solutions
Laser-based measurement technologies such as Raman spectroscopy and Tunable Diode Laser Absorption Spectroscopy (TDLAS) continue to gain ground over alternative methods such as gas chromatography or mass spectrometry. With no moving parts and very little sampling needed, the process analyzers used as such are easier to maintain and provide highly accurate results in seconds. This enables smarter control of rapidly changing processes in real time, without human exposure to hazardous chemicals.
Our analytical solutions provide fast, real-time measurement of chemical compositions with minimal operational costs and safety risks. We are experts in developing custom analytical solutions that overcome unique measurement challenges, including the design of probes, analyzer racks, and process-specific shelters.
Reaction end point detection and kinetic control. Polymerization in an emulsion produces a wide range of polymeric materials, including paints, adhesives, and synthetic rubbers. This type of reaction is carried out within an aqueous environment where the monomer species is kept within a single phase with a suitable surfactant or emulsifier. Raman spectroscopy is well suited for monitoring these reactions insofar as it is sensitive to the measurement of specific double bonds and does not suffer from interference from the aqueous matrix.
TDLAS analyzers monitor the quality of feed gases by selectively measuring contaminants such as ammonia (NH3), moisture (H2O), or acetylene (C2H2). These measures help improve process control, meet product specifications, prevent catalyst poisoning, and minimize flaring. The analyzers provide reliable measurements in seconds, allowing quick actions. We offer complete analyzer solutions comprising a sample conditioning and extraction system and suitable analyzer housings.
Online monitoring of product properties and quality. Polymerization reactions are often carried out in a semi-continuous mode. This allows careful control of product composition to create high performance materials with finely tuned custom properties. During the reaction, strict control of reagent concentrations is necessary to avoid unwanted properties in the final product. Simply adding the reagents in the correct ratio is insufficient.
