Fixed sample position “bottom-up” geometry bench-top metal spectrometer for determination of precious alloys is and jewellery samples
InnoSphere the well-known organization consist group of professionals, each having several years of experience in the field of analytical, scientific, process, test & measuring instrumentation. The company with its experience for more than 2 decades in X-ray technology introduces always innovation in precious measurements with latest hardware, intuitive software and simplicity in operation at affordable cost.
Karatmeter G-series is bench-top, fast, precise & non-destructive unit for accurate elemental analysis. Fixed sample position precisely & swiftly determines the percentage by weight (or Karat) in a solid piece of jewellery, precious coins or any other piece of noble metal making use of X-ray assay technique. It successfully determines the elemental composition of Gold alloys, Platinum group metals & Silver alloys. The analysis of bulk material & layer thickness is non-contact and non-destructive without any requirement for sample preparation. With additional calibration module, it can be even use for special coating thickness applications and plating chemical analysis.

Who Benefits
Karatmeter G-series metal spectrometer is ideal for labs and production lines, particularly where users have:
The two most distinctive features of the G-series are precision video imaging, and "bottom-up" measurement using a fixed plate or optional motorized z-axis with laser-based auto-focus. An optional manual X-Y stage with 1.5X1.5" travel facilitates easy positioning of small and large parts. These features are unique as compared with other suppliers.
The standard configuration includes a dual collimator, a camera with a fixed focal distance, solid-state silicon PIN detector, and a long-life X-ray tube. As with all existing or new models, components can be upgraded to include multiple collimators, a variable focal depth camera or high resolution SDD/FSDD detector.
