Urea and ammonium nitrate concentration in urea-ammonium nitrate fertilizer (UAN): inline composition control
The plant produces RSM 28, 30, or 32 to customer order on a single continuous mixing installation. Hitting the specification window of the selected type and...
Case studies
Monomer conversion and copolymer profile in acrylic dispersions and resins: inline measurement
In dispersions and acrylic resins, the copolymer composition and its homogeneity determine the glass transition temperature Tg and coating properties, while residual monomer is...
Case studies
Verification of the F/U ratio and formaldehyde concentration in UFC concentrate upon receipt
The molar ratio F/U in UF resin is the fundamental parameter determining formaldehyde emission from the finished board, and it follows directly from the composition of the received...
Case studies
Melamine control in MUF resin synthesis – dosing and real-time reaction progress
Melamine is the most expensive component of the MUF formulation, and resin properties are determined not only by how much is added, but also by whether it has had time to react...

Synthesis progress and free formaldehyde in melamine (MF) and melamine-urea (MUF) resins: inline measurement
Acceptance of a melamine resin batch is determined by two factors: hitting the condensation endpoint and the free formaldehyde content, which the customer treats as a criterion...

Continuous monitoring of petroleum-derived hydrocarbons in wastewater
At a municipal water and wastewater utility, we launched one of the first Polish deployments of the Spectrally™ water analyzer. The system detects petroleum hydrocarbons directly in the flow, in…

Control of urea concentration in AdBlue/DEF (ISO 22241, 32.5%)
AdBlue must meet a concentration of 32.5% ±0.7% per ISO 22241; deviation destroys the SCR system. We demonstrate how to verify urea concentration and solution homogeneity…

Total nitrogen in fertilizer granules: in-line measurement, no sample preparation
In a feasibility study at a fertilizer manufacturer, we showed that Raman with a 1064 nm laser measures total nitrogen directly on the granulate, without sample preparation,…

Control of ammonium thiosulfate (ATS) concentration in sulfur fertilizer
Ammonium thiosulfate (ATS) must meet concentration specifications and the N/S ratio, while offline measurement takes 20 to 60 minutes. We demonstrate how…

Acid number of alkyd resins: real-time control of the esterification endpoint
In a feasibility study at a resin manufacturer, we showed that in-line Raman measurement predicts the acid number, and additionally the viscosity, with accuracy approaching…

Inline measurement of formaldehyde (HCHO) concentration in formalin production
Today, a formalin manufacturer verifies HCHO concentration using sulfite titration lasting 30–45 minutes. We demonstrate how to measure HCHO, methanol, and paraformaldehyde concentrations directly in the line,…

Real-time determination of the polycondensation endpoint of resins (UF/MUF)
In a feasibility study at a urea-melamine resin manufacturer, we developed an inline indication of the polycondensation reaction endpoint, replacing manual post-hoc viscosity measurement.
Case studies
F/U ratio and free formaldehyde in urea-formaldehyde (UF) resin: real-time reaction control
In urea-formaldehyde resin production, the formaldehyde/urea ratio and the level of free formaldehyde determine product reactivity and emissions. We demonstrate how to control them directly in…
Case studies
Free formaldehyde in phenol-formaldehyde resin: the second critical analyte of a single installation
At a phenol-formaldehyde resin manufacturer, the same measurement system that controls free phenol simultaneously measures free formaldehyde. We demonstrate how to monitor both with a single inline measurement…
Case studies
Free phenol in a phenol-formaldehyde resin reactor: real-time measurement
At a phenol-formaldehyde resin manufacturer, we implemented free phenol measurement directly in the polycondensation reactor, in real time and in a medium that clogs conventional probes.…

Feasibility assessment of using Raman to differentiate white paint batches and identify mineral filler markers
As part of a feasibility study, we examined whether Raman spectroscopy allows for the rapid and unambiguous differentiation of two white paint samples and to identify the source of...

Identification of raw materials for adhesives in seconds – mobile delivery inspection with Spectrally™
At an adhesive manufacturing plant, we implemented a mobile analyzer from the Spectrally™ family for rapid identification of raw materials at the delivery acceptance stage – without opening transparent…

Real-time quality control of alkyd resins: correlation of viscosity and acid number with Raman spectra
In alkyd resin production, every minute counts – the sooner you detect quality deviations, the fewer costly adjustments and material losses. At Gekko...
