ETR Laboratories is not just a water testing company. We are a full service analytical laboratory with research grade instrumentation and over 31 years of experience serving industrial, commercial, medical, government, and academic clients across the country. When your process, your product, or your facility depends on accurate analytical results, ETR has the equipment and expertise to deliver them.

Industrial Process Water and Cooling System Testing

Water quality directly affects the performance, efficiency, and longevity of industrial systems. Cooling towers, boilers, circulating systems, and manufacturing process water can all experience accelerated corrosion, scale formation, organic fouling, and sediment buildup when water chemistry is not properly monitored and controlled. These problems do not just reduce efficiency. They cause equipment failure, production downtime, and significant unplanned maintenance costs.

ETR provides comprehensive water system and cooling system testing for commercial buildings, hospitals, data centers, and manufacturing facilities. Our recurring service programs give facility operators and engineers the data they need to stay ahead of chemistry problems before they reach equipment. Services in this category include:

  • Cooling tower water analysis
  • Boiler water chemistry testing
  • Glycol analysis including freeze point, inhibitor levels, pH, and reserve alkalinity
  • Glycol HVAC system analysis
  • Corrosion monitoring and metal analysis
  • Legionella testing
  • Lubricant and oil analysis
  • Corrosion and scale deposit analysis
  • Product efficacy testing for water treatment chemicals

Materials and Surface Analysis

ETR’s scanning electron microscope and EDS capabilities make us a trusted resource for engineers and manufacturing quality assurance teams requiring precise materials characterization. We perform SEM microscopy, EDS elemental analysis, particle identification, surface contamination analysis, and residue analysis on a wide range of materials and samples. Our FTIR spectrometer adds molecular identification capability for unknown substances, polymer identification, and contamination sourcing. These services are used by engineers troubleshooting manufacturing defects, QA teams verifying material composition, and environmental and legal investigations requiring documented analytical findings. Services in this category include:

  • SEM microscopy
  • EDS elemental analysis
  • Particle identification
  • Surface contamination analysis
  • Residue analysis
  • FTIR unknown identification

Dialysis Water Testing

Dialysis water is among the most demanding water quality applications in existence. Water used in hemodialysis comes into direct contact with a patient’s bloodstream through the dialysis membrane and must meet strict purity standards to protect patient safety. Trace contaminants that would be acceptable in drinking water can cause serious adverse reactions in dialysis patients. ETR Laboratories provides dialysis water testing for dialysis centers, hospitals, and healthcare facilities requiring verified analytical results for their water treatment compliance programs. Our instrumentation and methodology meet the precision requirements this application demands.

Quality Control, Reverse Engineering, and Unknown Analysis

Manufacturers and industrial operations that depend on consistent input water quality or process water purity rely on ETR for ongoing quality control testing. We work with clients across a range of industries to establish baseline parameters, monitor for deviation, and provide the documented analytical results required for internal quality programs, regulatory compliance, and customer verification.

When you need to know exactly what something is made of, ETR’s analytical capabilities are among the most comprehensive available in a private laboratory setting. We perform reverse engineering and compositional analysis on substances, materials, formulations, and process samples using instrumentation that can identify elemental composition, molecular structure, organic compounds, and trace contaminants at very low detection levels. This capability is used by manufacturers troubleshooting process changes, companies verifying product purity, researchers characterizing unknown materials, and legal and environmental investigations requiring independent analytical documentation.

Our Instrumentation

ETR’s laboratory is equipped at a level that rivals university research facilities. Our analytical instrumentation includes:

  • Two scanning electron microscopes with EDS elemental analysis capability
  • Nuclear magnetic resonance spectrometer (NMR)
  • Two ICP-MS systems for trace elemental analysis
  • Two GC-MS systems for organic compound identification
  • Two liquid scintillation counters
  • High performance liquid chromatograph (HPLC)
  • Three capillary electrophoresis systems
  • FTIR spectrometer for molecular identification
  • Total organic carbon analyzer (TOC)
  • Endotoxin meter
  • Multiple HACH instruments
  • Full wet bench chemistry capabilities

Every analysis is performed by our own scientists in our own facility. No outsourcing, no routing to outside labs, no guesswork about who ran your test or how.
