The Sievers iOS lets you run grab samples on the 900 On-Line or 500 RL without taking these instruments off-line.

Integrated On-Line Sampling System (iOS)

The patented Integrated On-Line Sampling System (iOS System) enables easy introduction of external standards and samples, and is available on the Sievers 900 and 5310 C On-Line, Laboratory and Portable TOC Analyzers, as well as the Sievers 500 RL On-Line. This unique feature allows users to introduce calibration, validation, and system suitability standards directly without removing the instrument from the continuous sample source or changing the sample inlet configuration. The IOS System also accommodates grab samples for spot checks of TOC samples from other locations in a water system.
