CFC-free oil-in-water testing by QCL-IR technology - ASTM D7678
The cost-cutting and eco-friendly analyzer with the patented QCL-IR technology allowing an extraction with the inexpensive and CFC-free solvent Cyclohexane. With its high speed and precision, it is the instrument of choice to detect even sub-ppm concentrations of total petroleum hydrocarbons (TPH) or total oil & grease (TOG) in water in full compliance with ASTM D7678.

Analyze Oil in Water with Highest Precision
Sub-ppm concentrations of Total Petroleum Hydrocarbons
(TPH) and Total Oil and Grease (TOG) in water and soil
all measurements done with cutting-edge QCL-IR technology
based on highly precise Quantum Cascade Laser science and in full compliance with the latest ASTM D7678 standard.
The ERACHECK is portable and rugged and therefore ideally suited for the use in laboratories as well as in the field.
In 1989 the Montreal Protocol regulated the phasing out of ozone-depleting
substances such as CFCs and HCFCs. As a consequence, oil-in-water testing
had to shift from the well-established IR techniques using CFC solvents to
more laborious methods, such as gravimetry or high-maintenance gas chromatography.
In 2001 the European IR standard DIN 38409-H18 was withdrawn
and in 2013 the ASTM committee removed the ASTM D3921 method after
having published, in 2011, a completely new IR method. This new standard,
ASTM D7678, brought back the benefits of IR measurement without the
drawbacks of the old methods. Instead of ozone depleting CFCs, the new
method advocates the use of cost-saving and readily available cyclo-
hexane as solvent in the extraction process. With the ERACHECK and the
ASTM D7678 method the days of measurement techniques still using expensive
and hazardous CFC solvents are finally numbered.
Cutting-Edge QCL Technology
The ERACHECK uses an infrared Quantum Cascade Laser (QCL), which acts
as its very powerful light source. It was the combination of this high-tech
laser and the patented measurement assembly that made it possible in the
first place to use CFC-free solvents for measuring Total Petroleum Hydrocarbons
(TPH) as well as Total Oil and Grease (TOG). Using a QCL also
helped to miniaturize the device while increasing its overall measurement
Quantum Cascade Laser technology outperforms standard infrared spectroscopy.
This results in highest precision measurements.
Ease-of-Use in the Field
Sampling and extraction is done as known from established methods. At the push of a button ERACHECK measures the extracted sample and displays the result on the large full-color touch screen. With its rugged aluminum housing, a built-in industry-proven PC and an auto-switching power supply ERACHECK is the ideal device for on-site operation.
Specially designed cartridges remove water and polar substances (grease). They simplify the direct measurement of TPH according to ASTM D7678.
Autosampler for Unattended Analysis
The 10-position autosampler lets you maximize your sample throughput while
saving precious operator time. The sampler is directly attached and performs measurements without operator intervention.
Unique Measurement Precision
The ERACHECK shows linear behavior in the range from 0.5 to 2000 mg/L with a repeatability of 0.2 mg/L in the range from 0.5 to 10 mg/L. At the highest end of the concentration range the ERACHECK still delivers an excellent repeatability of 2 mg/L
In extensive field tests ERACHECK showed excellent correlation to gas chromatography (e.g. ISO 9377-2 OSPAR) and gravimetric (e.g. EPA 1664A) as well as infrared (e.g. ASTM D7066) methods.
Thanks to this remarkable measurement range in combination with the highest precision currently available the ERACHECK clearly outperforms its competitors on today’s market.

... for All Applications
The prevention of hydrocarbons in discharged water can be a challenge in many branches of the petrochemical industry. The ERACHECK measures the Total Petroleum Hydrocarbons (TPH) and Total Oil and Grease (TOG) in
- Produced water
- Reinjection water
The ERACHECK is used for process control in the petrochemical industry for
- Upstream oil recovery
- Downstream process water monitoring
- Purity control in the chemical and energy industries
In environmental monitoring the ERACHECK is used in
- Testing for compliance with environmental regulations
- Bilge water monitoring in marine transportation
The contamination of surface soils by various types of crude oils and their products can be controlled by the ERACHECK. The included ERACHECK method “Oil in Soil” provides fast and reliable results for the concentration of oil-in-soil.
PERFORMANCE YOU CAN RELY ON
Fast & Easy Operation
All eralytics analyzers use an intuitive menu structure that is easy to navigate. Measurements are done fully automated.
The results are displayed immediately after the test on the large and userfriendly color touch screen. An internal memory holds the measurement results. For convenience, data can be directly saved to USB memory sticks for further processing or a thorough analysis. The data format is compatible with most PC spreadsheet programs, such as Microsoft© Excel. Customized print-out designs are available for easy direct printing.
Oil-in-water testing in six easy steps with ERACHECK
