*"*With remarkable precision, the QLX9 has proven a clear correlation between XRF and OES values*.“*
**Dr. Matti Aula**
*R&D at Outokumpu, Finland*
"Quantolux’s customer support has been consistently responsive and solution-driven, ensuring minimal downtime and full confidence in the equipment."
**Agustin Dominguez**
*Vice President Operations at SUDOSILO S.A, Argentina*
"I really enjoy working with the QLX9: just break and measure – and the slag is gone in no time. Compared to the old process, it’s a great relief."
**A Laboratory Engineer, operating a QLX9 on daily business**
"You can feel free to share my contact information with your potential customer in the USA. We certainly have plenty of positive feedback to share."
**A QLX9 customer in the United States**
With our new VD unit, controlling ladle slag online became crucial. Slag composition was often hard to predict, affecting process stability and degassing. The QuantoLux rapid analyzer lets us measure slag in seconds and make precise corrections, improving degassing efficiency and consistently achieving high product quality.
**Vid Vengust**
*Melt Shop Technologist in Štore Steel, Slovenia*
“… All in all, Quantolux was a highly valuable investment with relevant benefits in Capex and Opex.”
**Antonio Della Gaspera**
*Acciaierie di Verona, Gruppo Pittini, Italy*
