The Florence Bascom Geoscience Center requires a new handheld X-ray fluorescence (XRF) analyzer for field and laboratory use. This equipment will facilitate sample collection and mineral identification. Key specifications include a large-area drift detector for various sample media, the ability to analyze specific elements (including rare-earth elements) without a vacuum, and accessories for hands-free field use. The XRF must feature built-in excitation filters, a tiltable color LCD display, and not be solely dependent on Windows OS. It should weigh less than 4 lbs, have an Ag target X-ray tube, and include two independent processors. Essential accessories are a radiation-shielded portable stand, certified reference standards, a sample preparation kit, and a 3-year warranty. The analyzer also needs Bluetooth, a touchscreen, a carrying case, a battery charger, operational training, rugged housing, long battery life (>6 hours), fast analytical throughput, and compliance with EPA Method 6200. It must support both large and small sample areas and include radiation safety features.
The Florence Bascom Geoscience Center requires a new handheld X-ray fluorescence (XRF) analyzer for field and laboratory use. This equipment will facilitate sample collection and provide rapid mineral screening. The XRF analyzer must meet specific technical requirements, including a geometrically optimized large area drift detector for various sample media and applications such as exploration and grade control. It must analyze a comprehensive list of elements, including rare-earth elements, without a vacuum or purge system for light elements like Mg and Al. Key specifications include hands-free accessories, built-in excitation filters, a tiltable color LCD, non-Windows operating system dependence, a weight under 4 lbs, an Ag or Rh target X-ray tube, dual independent processors, and a fully radiation-shielded portable stand. Additional requirements cover certified reference standards, a sample preparation kit, a 3-year warranty, Bluetooth connectivity, light element analysis capability, software, a touchscreen, an imaging camera with at least 5-megapixel resolution, an integrated GPS receiver, a carrying case, a battery charger, operational training, rugged housing, long battery life with hot-swap capability, fast analytical throughput, compliance with EPA Method 6200, large area measurement capability, and radiation safety features. This acquisition is crucial for enhancing the center's analytical and field capabilities.
