On-line measurement of Co, Br, Mn in TPA and PTA
Author(s)Applied Rigaku Technologies, Inc.
Terephthalic acid (TPA) and purified terephthalic acid (PTA) are precursors in the making of polyester PET for polyester films, bottle resin, textile fabrics, and specialty chemicals. During production and use of TPA and PTA, the catalysts Co, Br and Mn must be closely monitored to ensure optimum product quality. Rigaku EDXRF Application Note #1539 describes the analysis of concentrations of Co, Br and Mn in TPA and PTA solutions and highlights the performance of the Rigaku NEX OL on-line EDXRF process analyzer.

Wednesday's program at SciX 2026 kept returning to one question: can spectroscopy perform outside the controlled laboratory? Speakers took surface-enhanced Raman scattering (SERS), laser-induced breakdown spectroscopy (LIBS), mid-infrared photonics, chemometrics, and fluorescence excitation–emission matrix (EEM) spectroscopy into clinics, food plants, reactor coolant loops, brine fields, and drinking water supplies.
Spectroscopy invites the scientific community to nominate an outstanding early-career atomic spectroscopist for the 2027 award. Nominations are due December 10, 2026.
