Salient Characteristics

1.        An X-ray fluorescence core scanner capable of analyzing both marine sediment and mineral cores

2.        The XRF should have the ability to analyze both wet and dry cores

3.        The XRF should have the ability to analyze elements from magnesium through uranium or better with high precision and sensitivity to both heavy and light elements

4.        The XRF should have the ability to analyze samples up to 1.5 m in length at 1 mm resolution or better

5.        The XRF should have appropriate safety shielding for x-rays

6.        The XRF should have energy resolution of 3% or better

7.        The scanner should be equipped with an RGB camera that collects images paired to the XRF scan at a resolution of 50 micrometers or better

8.        The XRF should be supplied with an appropriate X-ray tube with a reliable lifetime and appropriate power supply and shielding

9.        The scanner should be supplied with a means of holding the samples during analysis and NIST certified reference material

10.        The XRF should be supplied with software for data collection and analysis, including spectral deconvolution for elements with overlapping energy levels

11.        The XRF should be supplied with a one-year standard warranty, as well as product installation and appropriate user training.
