On-line measurement of Co, Br, Mn in TPA and PTA
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.
New Study Reveals How NASA’s Perseverance Rover Uses LIBS for Precise Mars Rock Analysis
November 12th 2024NASA’s Perseverance rover is collecting valuable information for scientists back on Earth. A recent study explored how laser-induced breakdown spectroscopy (LIBS) is being used to analyze the Martian surface.
Simultaneous Determination of 50 Elements in Geological Samples by ICP-MS Combined with ICP-OES
October 15th 2024A method combining inductively coupled plasma–mass spectrometry (ICP-MS) with inductively coupled plasma–optical emission spectrometry (ICP-OES) was developed for multielement determination of 50 species of major, minor, micro, and trace, rare earth, and rare elements in geological samples.
