On-line analysis and water testing

October 2012 Analytical Instrumentation & Environmental Monitoring

Galvanic Applied Sciences USA manufactures the complete brand of Tytronics on-line wet chemical and gas analysers. The Tytronics products include the Sentinel on-line analysers, which use state of the art technology to perform colorimetric, titrimetric, ISE, and spectrophotometric analyses. These analysers can be configured to perform many EPA and ASTM wet chemical methods, as well as many standard methods. The Sentinel analysers use a modular design that can be configured to meet the specific requirements of the customer’s application.

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 be 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.

The Tytronics Sentinel is an on-line analyser capable of both process chemical analysis and the monitoring of potable water and wastewater. The unit offers accurate measurement qualities and accuracies coupled with built-in reliability, thanks to a simple and sample capture system and wide-bore tubing. It is an analyser built to handle difficult and dirty samples.
