Our Online Analyzer Methods

LAS online analyzers are capable of multiple analytical methods and are offered with a full suite of features and options for automatic, unattended operation. Here are our four basic analytical method categories:


Stable and versatile, carrying out both known and specialty techniques. This well-known method is the most fundamental and established.


Auto-calibrated and temperature-compensated for maximum stability and accuracy. Our at-line approach is also isolated from the process for maximum probe longevity and overall reliability.


A rapid, multicomponent analysis method. It is used to distinguish components in mixtures and is often accomplished without reagents or sample loss.


Utilizing sensitive and proven methods including EPA approved methods for water and wastewater analysis.

Our Analyzer Features and Options

LAS analyzers may be thought of as an atline “laboratory in a box” – complete with sampling, analysis, reporting/alarming, cleanup, and even auto-calibration for continuous, unattended operation. And the LAS design is accomplished with minimum maintenance in view: for example, no peristaltic pumps are used and no pump tubing replacement is required! In most cases, a quarterly PM is all that’s needed.
