New ATONA Instrument Data
As the new Phoenix instruments with the ATONA amplifiers move through production we have a lot of new data to share. Here we are running 5ng loads of NIST SRM 987 from a recent Phoenix installation. The average internal precision is 3.6ppm while the external is 5.68ppm.

We also have some very exciting data showing the analysis of Calcium. For a 1000ng load, the average internal precision for 40Ca/44Ca is 14ppm 1RSE,while the external precision is 25.1ppm 1RSD.

Please stop by and see us at the Goldschmidt 2018 meeting in Boston (booth 43) we will have lots more data to share.
