Sievers M500e Online TOC Analyzer

Detect critical organic contaminants, optimize yield, and ensure ultrapure water quality with new Sievers M500e Online TOC Analyzer

For microelectronics applications and analysis of low-level contaminants, the Sievers M500e builds on the stability of the prior model, the Sievers 500 RLe TOC Analyzer. It advances on the decade-long Sievers legacy with an updated interface, accuracy at ultra-low-levels, and results within minutes.

The M500e will continue to prove critical for microelectronics applications that require ultrapure water quality and is valuable for steam generation systems to analyze low-level contaminants.

Maintaining use of Sievers' reagentless Membrane Conductometric technology still offers high accuracy with an operating range of 0.03 ppb to 2.5 ppm. This new model introduces significantly reduced wait times for results, faster rinse down to sub-ppb levels, and adaptive autozero.
