Water monitoring and on-line analysis

May 2013 Analytical Instrumentation & Environmental Monitoring

The Tytronics Sentinel is an on-line analyser capable of both process chemical analysis and the monitoring of drinking water (potable water) and wastewater. Offering an attractive price/performance ratio, the analyser provides both measurement quality and accuracy. A simple and patented sample capture system and wide-bore tubing ensures that the analyser can handle difficult and dirty samples reliably.

Simple menu-driven operation and a modular design make the Sentinel easy to use and maintain. A person with little chemical background can use the analyser with minimal training; simple step by step instructions are displayed to guide the operator through the procedure to complete a calibration and to set the unit in the automatic analysis mode.

The best methodology for the application

One of the keys to Tytronics’ leadership in on-line analysis is the commitment to provide the best possible methodology (colorimetry, ISE, colorimetric or potentiometric titrations) for the application at hand. Thus, users are assured that measurements of acids, ammonia, bases, metals, nitrate and phosphate, etc, are done in the very best way.

All parameters in the Sentinel are user programmable and multiple analysis methods can be configured to tackle different concentration ranges. Multiple calibration setups can be used to define different low and high-range calibration curves. A cleaning cycle can also be programmed to clean out or dissolve any build-up on the measurement sensor or reaction cell. Analysis, calibration and cleaning cycles can be executed at periodic (user-programmable) intervals to provide hands-free automation of the analyser.

Unique batch sampling capture technique

The patented sample capture technique incorporated into the Sentinel provides a simple and reliable method of capturing a reproducible volume of available sample. The inlet uses 6 mm tubing, thus minimising blockages and allowing even high turbidity samples to be readily handled.

The sample inlet system uses an internal fast loop ensuring that a fresh and representative sample is always available for analysis. Sample capture volume can range from 5 to 30 ml. This allows the unit to be used for ppb as well as ppm levels of measurement.

Mixing is accomplished through the use of a magnetic Teflon coated stir bar. Two types of measurement sensors, colorimetric and potentiometric, can be mounted in the reaction cell.

Peristaltic pumps are used to introduce calibrating and cleaning solutions. Reagents are introduced through high precision positive displacement piston pumps which require minimum maintenance.
