Analytical Instrumentation New Tube-Above WDXRF Spectrometer Features Advanced Guidance
System and Automatic Application Setup Wavelength dispersive X- ray fl uorescence (WDXRF) analysis is known for high detection sensitivity and spectral resolution offering non-destructive trace element analysis, and is often employed by research institutions and for quality control. The new Rigaku ZSX Primus IV spectrometer is a high-power sequential WDXRF analytical tool for research and development, and for the analysis of advanced materials and products. It leverages recent advancements in data processing using the fundamental parameters method, and delivers rapid quantitative determination of major and minor atomic elements with minimal standards. The ZSX Primus IV spectrometer features a tube-above confi guration. Due to the tube-above optics, powder sample spills do not adversely affect the optical system. Since no protective fi lm is required, intensity reduction due to fi lm is avoided. The unit features a 30 micron tube, tube for exceptional light element (low-Z) detection limits. Light element sensitivity is also boosted by the system’s APC (Auto Pressure Control), which regulates and stabilised vacuum conditions. Combined with the most advanced mapping package to detect inclusions and eliminate sampling errors in inhomogeneous materials, the ZSX Primus IV allows easy, detailed investigation of samples that provide analytical insights not readily obtained by other analytical methodologies. A key new advantage to this system is the new ZSX Guidance ‘expert system’ software, with a quantitative application auto-confi guration feature to set measurement and various correction conditions once the user enters the standard values and sample information. Throughput is also greatly improved by high-speed sample transportation, high-speed goniometer drive, high-speed data processing and effective driving control. During analysis, regions of interest can be located in enlarged images of the sample taken with a high-resolution camera. The r- sample stage can be accurately positioned to facilitate measurements with uniform sensitivity on these small areas.

PAC is launching the next generation of the ISL FZP 5G2S, the world’s leading Freezing Point Laboratory Analyser. The newly redesigned OptiFZP offers improved productivity with proven reliability and accuracy. The user-friendly interface on a 7.1” colour touch screen allows users to start a test with just the touch of a button and view a real-time graphic display of the test, improving customer experience and accelerating lab productivity. The patented built-in cooling system, unique detection cell, and automatic cleaning help lower the cost of ownership, while producing accurate results up to -100°C (-148°F) in under 15 minutes. The new model includes all the standard data exporting capabilities (USB, RS232, network printing) as well as LIMS connectivity through the IRIS platform. OptiFZP offers superior correlation to the manual method with excellent sensitivity to contaminated samples. This proven analyser is compliant with ASTM D7153 and IP 529 and has perfect correlation to ASTM D2386 and IP 16.

Detailed Sulphur components, Arsine and Phosphine are traditionally analysed by GC methods using selective and sensitive detectors like FPD, PFPD and SCD. GCMS is less often used but offers evident advantages. Excellent linearity is demonstrated for volatile Sulphur components starting as low as 1 ppb (see the illustration: 4 ppb H2S and 2 ppb COS). For Arsine and Phosphine limits of detection below 10 ppb are shown. The use of Quadrupole MS detection provides positive identifi cation for other components as well like Oxygenates at low ppb level in various matrices.
