Product Description

The Phoenix TIMS combines our proven source design and optics with newly developed detector technologies to produce the highest precision data. The Phoenix is completely customizable to suit the needs of your lab now and future-proofing your lab for new applications.

The Phoenix TIMS (thermal ionization mass spectrometer) is designed to measure isotope ratios of non-gaseous elements with the highest sensitivity and precision. Careful design of the ion extraction optics combined with high vacuum around the ionizing filament results in a highly sensitive instrument, while low-noise, stable detectors that measure extremely low ion currents maximize precision. The Phoenix represents the ultimate combination of all these factors, giving you the breadth of analytical capabilities that you need.

ATONA®

The unique, patented ATONA (aA to nA) amplification technology from Isotopx has eliminated the need for a feedback resistor. The outcome is a significant reduction in amplifier noise, a dramatic increase in dynamic range, rapid amplifier decay, and improved baseline and calibration stability. But what does this mean for your analysis?

In practice, this means analysis of signal sizes from tens of counts per second to nanoamps (hundreds of volts) with lower noise than any resistor-based amplifier. So you can analyze a wider range of sample sizes than ever before, with more confidence in your data.

Our unique ATONA technology vastly improves analytical flexibility.
