Description
The InfraCal 2 TRANS-SP is recommended for measuring oil in water, TPH in soil or FOG in wastewater concentration levels using the traditional EPA methods 413.2 and 418.1 or ASTM method D7066-04 and Freon-113, hydrocarbon-free grade of perchloroethylene, AK-225, S-316 or other spectroscopic infrared transparent solvent as the extracting solvent. Since the extract is deposited into a 10 mm quartz cuvette cell with Teflon stopper, light end volatile components are retained for measurement. Accurate down to 0.1 ppm.
The InfraCal 2 TRANS-SP, the latest introduction to our easy to use analyzers, uses the same measurement technology as the original InfraCal Model CVH, with added features such as data storage and transfer, multiple calibrations and password protection for instrument settings.
FAQ
What is the LOD of the InfraCal 2 TRANS-SP?
The InfraCal 2 TRANS-SP has a minimum detection limit of 0.2 ppm for oil in water and 2 ppm for oil in soil.
What is the highest range of measurement for the TRANS-SP?
The InfraCal 2 TRANS-SP can be calibrated to measure up to 2000 ppm oil in water or soil.
Why do the standards read differently than the value displayed on the label?
If the instrument is calibrated for a 10:1 extraction, the standard will read approximately a factor of 10 lower than the labeled value of the standard. For example, a standard labeled 500 ppm will read 50 ppm. For instruments calibrated for a 1:1 extraction, the instrument will read approximately the labeled value of the standard.
Which solvents can be used with the TRANS-SP?
The most common solvents used with the InfraCal 2 TRANS-SP are tetrachloroethylene and S-316. For tetrachloroethylene, it is important that the purity is greater than 99% and there are NO stabilizers added. Contact Spectro Scientific for any questions on the usability of any specific grades of solvents or any alternative solvent types.
How long does a calibration last?
A calibration lasts anywhere between one year and many years depending on frequency of use and environment. We recommend do an annual calibration verification and recalibrating when necessary.
Operating Principle
The InfraCal TOG/TPH Analyzer makes use of the fact that hydrocarbons such as oil and grease can be extracted from water or soil using an appropriate solvent and extraction procedure. The extracted hydrocarbons absorb infrared energy at a specific wavelength and the amount of energy absorbed is proportional to the concentration of oil and grease in the solvent. The analyzer can be calibrated to read out directly in the desired units.
