UV-Vis Process Analyzer for Process Environments - Model 508

The Model 508 plus Process Analyzer can be made available as either a single or multi-channel fiber optic UV-Vis spectrometer system that has been specifically designed to be used in process environments. With configuration capabilities of up to four channels, the Model 508plus sits within a NEMA 4x enclosure that is equipped with its own thermal control system to ensure that the most consistent performance rates are achieved while in 24/7 service mode.

With up to 16 possible parameters being monitored on each channel, the Model 508 Process Analyzer is a suitable tool for numerous applications ranging from those occurring within chemical and polymer plants, refining and petrochemical, pharmaceuticals and other specialty chemicals, paints and varnishes, adhesives, wastewater management, biotech and much more. With its own built-in computer control unit and optional touch screen, the Model 508 is an ideal tool that provides a convenient user interface.

Some of the most common applications of the Model 508 Process Analyzer include, but are not limited to the following:

L*a*b* and other color coordinates

Solvent recovery purity

Maleic acid in tetrahydrofuran (THF)

Trace (ppm level) impurities in wash water; Clean-In-Place for Pharma

Polynuclear aromatics (PNAs) in middle distillates

Phenol in cyclohexanone

Sodium hypochlorite in bleach solutions

Aromatics in monomers

Benzene in cyclohexane

Saybolt or ASTM color of diesel and jet fuel

Toluene diisocyanate in polyurethane

UV inhibitors in polymers

Antioxidants in polymers and plastics

Color and clarity of varnishes

Halogens and various halogenated compounds in vapor streams

Sorbic acid in water

Ferrous chloride in acid

Acetonitrile purity

Hypochlorous acid

Reliable, Rugged, and Flexible Tool

With over 35 years of experience in online process monitoring and stream sample analysis, Process Insights combines unique designs and developments to the Model 508 process analyzer that is capable of meeting the specific challenges associated with the most demanding production environments. Modular units exemplified by the Model 508 plus’s ‘snap tight’ installation dock is highly preferred for this purpose. Additionally, the use of a Plused Xenon source lamp has a lifetime lasting over two years.
