25 Van Zant Street, Ste. 8F, E. Norwalk, Connecticut 06855, United States of America



Spectro Scientific focuses on developing, manufacturing and selling application-specific, mid-infrared (mid-IR) analytical instrumentation for both qualitative and quantitative measurements.

All Spectro Scientific analyzers and spectrometers are designed for easy, onsite field or at/near line use. They are equally as useful virtually anywhere repetitive measurements are needed, whether is is in the analytical or testing laboratory. Spectro Scientific instruments are the ideal solution for a wide variety of measurement applications in the biofuels, petrochemical, environmental, quality control and manufacturing industries.

Spectro Scientific analyzers have easy-to-use operator interfaces, making them ideal for non-technical personnel with little or no analytical or infrared background. Users can quickly and accurately obtain on-site results, typically in less than a minute. They let you cost-effectively move the application out of the laboratory to the analysis location, eliminating the wait for off-site lab results. All Spectro Scientific products are virtually maintenance-free, providing years of dependable, trouble-free operation.

Easy-to-use analyzers for measuring oil content

InfraCal Analyzers are designed specifically to be rugged, compact (less than 5lb), and easy to use by non-technical personnel. With more than 3,500 in use worldwide, they have become the instrument of choice for on-site analysis of oil in water, providing measurement results in less than 15 minutes.

The analyzers eliminate the wait for off-site lab results to ensure that oil-in-water levels comply with discharge permits, as fines for non-compliant discharges can be costly.

InfraCal TOG / TPH analyzers:

  • Eliminate waiting for offsite lab results
  • Provide oil content measurements in ten to 15 minutes
  • Help avoid fines for out-of-compliance produced water discharges
  • Are easy-to-use by non-technical personnel
  • Use infrared technology based on DTI, EPA and ASTM methods
  • Have no effect on measurement from methanol
  • Are designed for years of dependable, accurate operation
  • Increased sensitivity for sub-parts-per-million (ppm) measurements
  • Password-protected calibrations and instrument settings
  • Multilingual user interface
  • Unlimited data storage and multiple calibrations
  • Touchscreen display for more options

Oil-in-water analyzers for non-technical personnel

Four InfraCal analyzer models are available for measuring oil content in water, drill cuttings and soil. All are ideal for use by non-technical personnel and provide virtually maintenance-free operation.

Both the InfraCal Model HATR-T2 and the new InfraCal 2 ATR-SP use hexane, pentane or Vertrel MCA for the extraction process. Measurement data from either model will correlate to EPA Method 1664, as both procedures are based on evaporation techniques and measuring the residual oil and grease. They are equipped with a built-in cubic zirconia horizontal attenuated total reflection (HATR) stainless-steel sample stage on which the extract is deposited for analysis.

The sample preparation takes a few simple steps and the ppm hydrocarbon result is obtained in less than 15 minutes. The InfraCal Model HATR-T2 has a minimum detectable limit of 8ppm oil in water and the InfraCal 2 ATR-SP will measure down to 0.3 ppm.
Both the InfraCal Model CVH and new InfraCal 2 Model TRANS-SP are based on US EPA Methods 413.2 and 418.1 and ASTM D7066-04, which uses Freon 113, perchloroethylene, or S-316, as the extracting solvent. Since the oil concentration is measured directly in the solvent, light end volatile components are retained, making it ideal for gas condensate measurements.

The sample preparation takes a few simple steps and the result is obtained in less than ten minutes. The InfraCal Model CVH has a minimum detectable limit of 2ppm oil in water. It was one of the instruments used to develop the ASTM D7066 oil in water method. The InfraCal 2 TRANS-SP will measure down to 0.1ppm.

In addition to lower detection limits, InfraCal 2 analyzers have added features, which include multiple calibrations to cover a larger range of analysis, data storage that tags measurements with analyst, date and time, and security features with different user access levels.

Oil-in-water analyzers based on infrared technology

The analysis of oil in water by infrared technology is not new to the oil and gas industry, as it has been used worldwide for more than 40 years. Unlike UV fluorescence, which only measures aromatic hydrocarbons, infrared measures both aromatic and aliphatic hydrocarbons.

If there is any change in the aromatic / aliphatic ratio in produced water, infrared will see little effect while UV fluorescent analyzers will require recalibration.

Whether you choose an InfraCal TOG/TPH Analyzer or a new InfraCal 2 model, all are accurate, cost-effective and easy to use by both skilled technicians and non-technical personnel. They provide an analysis method that is ideal for onsite use, as well as in analytical or testing laboratories.

Biodiesel blend and ethanol blend analyzers

With the increase of biodiesel and ethanol blended into petrol fuels, those involved in the downstream end of fuel distribution need a quick and easy way to measure how much biodiesel is blended in diesel fuel or ethanol into gasoline.

Using the same technology as the InfraCal analyzers for oil-content measurements, the InfraCal biodiesel blend and ethanol blend analyzers are compact, portable and designed for the rugged environment of a fuel terminal.

Benefits and features include:

  • No sample preparation necessary
  • Analysis less than one minute
  • Biodiesel measurement range from 0.2% to 100%
  • Ethanol measurement range from 0.2% to 98%

InfraCal 2 Oil in Water Analyzer

As effluent discharge regulations continue to become more stringent, often requiring an oil in water measurement of less than 1ppm, the InfraCal 2 Analyzer is the newest addition to the globally recognised Wilks InfraCal line of portable, filter-based infrared analysers.

Wilks Launches New Website

Spectro Scientific Company Wilks is pleased to announce new website www.WilksIR.com focused on providing users with easy to use portable analysers for a variety of practical on-site measurements.

Fast and Easy Onsite Measurement of Oil in Water and Hydrocarbons in Drilling Mud

Portable infrared (IR) analysers, such as InfraCal analysers from Wilks, have been used worldwide for measuring offshore oil in produced water for over 50 years. They have the advantage over other analytical instruments in that the measurement can be performed by non-technical users and it is relatively unaffected by composition changes in the effluent.

Spectro Inc. Acquires Wilks Enterprise

Leading Chelmsford, Massachusetts-based developer and manufacturer of analytical tools and software for the industrial performance fluids market Spectro Inc. has announced the purchase of Wilks Enterprise for an undisclosed sum.

Wilks Releases Free White Paper

By using careful analytical procedures, understanding the composition of the waste stream and knowing the limits of each measurement system, useful information can be generated from comparing oil and grease in water testing methods.

Sub-ppm Oil-in-Water Measurements in Less Than 15 Minutes with New Portable IR Analyser

The new InfraCal 2 field portable IR analyser can measure down to 0.1ppm oil in water accurately, onsite and in less than 15 minutes. It is the newest addition to the Wilks line of rugged, easy-to-use oil-in-water / soil analysers, and provides added sensitivity and features for today's most challenging environmental applications. InfraCal 2 is ideal for non-technical users and will provide years of dependable, maintenance-free operation.

Comply with Highly Regulated Oil in Water Measurements Using Portable Infrared Analysers

The petroleum industry - both offshore and onshore -- has regulations that limit the amount of oil in discharged water. Fixed filter infrared (IR) analysers have been used to test oil levels in produced water on drilling platforms for over 45 years for a number of reasons. On oil rigs where real estate is at a premium, infrared analysers such as the Wilks InfraCal TOG/TPH analysers are compact (typically 6in or 15cm², weighing less than 5lbs) and rugged enough to withstand salt air and a rustic lab set up.
