Oil in Water Analysis

Measures the amount of oil in process water, fresh water sources, or even salt water sources.  Capable of measuring trace oil in the Gulf Oil Spill or even in your own home.  Tap water can be contaminated after it leaves the town water processing facilities.  Similar to EPA 1664 method, but enhanced by using FTIR and a specialized filtration technique to extract oil from water.  Capable of detecting oil down to 50ppb of mineral oils in water.  This technique can also measure grease, clay, and bacteria in water.

 


Ultra Low level biodiesel in diesel analysis - Using specialized FTIR techniques we are able to measure biodiesel (FAME and any other ester impurities) in diesel fuel down to 15ppm.  This is in comparison to the ASTM 7371 method which uses FTIR to measure biodiesel down to 1% (10,000ppm) and the best European EN14078 method only measures down to 0.05% (500ppm) biodiesel.  The popular PAL FTIR biodiesel method from A2 Technologies measures the biodiesel level down to 0.025% (250ppm).

Above is the FTIR spectral overlay of biodiesel in diesel, the biodiesel peaks at 1741cm-1 (ester carbonyl stretch), 1170cm-1 (ester C-O stretch), 1196cm-1, and 1245cm-1 increase proportionally to concentration according to Beer's Law (Absorbance Law).  This law is common to most spectroscopic quantitative analytical techniques and is used to create an Infrared Varnish Index for used and in-process oil analysis.  This proprietary technique is used to identify and quantitate the degree of varnish potential of an industrial oil.  

Infrared Varnish Index - Determine the varnish potential of your oil in order to prevent a costly repair.
