NEXTChem Process Analyzers, Inc.

NEXTChem is located in Elmhurst IL U.S.A.

Our Mission is to build, support and continuously improve the Best Process Analyzers in the World!

NEXTChem Process Analyzers, Inc.

Sampling never requires a filter, decreasing maintenance and increasing reliability

Modern electronics makes programming through the User-Interface very simple

Using the latest innovations in stepper motor control for precise chemical analyses

Combining Multiple Chemical Analyses with Multiple Sample Streams within a single unit

What makes NEXTChem Analyzers different?

Types of Measurement Techniques

Titration Endpoint Determination(sulfite in sea water)

Standard Addition Ion Selective Electrodes(ammonia in wastewater)

NEXTChem Process Analyzers, Inc.

Types of Titrations

Acid / Base -Acetic Acid

Redox -Sulfide

Complexation -Cyanide

Precipitation -Chloride

Color -Hardness

NEXTChem Process Analyzers, Inc.

Three Types of Ion Selective Electrodes

Solid State Membrane:

The membrane is an insoluble crystal of the ion to be determined.

Example: Fluoride, Silver/Sulfide, Chlorine

Gas Permeable Membrane:

A gas permeable membrane separates the sample from the sensor, commonly pH electrode.

Example: Ammonia, Carbon Dioxide

Neutral Carrier Membrane:

The membrane contains an ion specific complexing agent.

Example: Nitrate, Potassium

Color Measurements

Color Dip Probe is used for the measurement:

630 nm Red, 590 nm Yellow, 520 nm Green, and 470 nm Blue

The following analyses can be done with the color measurements:

Filters must be changed frequently

Increases Maintenance Lowers Reliability

Creates a “fake” Sample

“The best filter is no filter”
