Sampling. Simple. Solved.
The ClearShot Extraction Technology® and method represents the next-generation solution to solventless oil and grease analyses in water and other solutions. The ClearShot system is based upon an environmentally friendly, optical-based solid phase extraction membrane technology that replaces liquid-liquid solvent-based extraction techniques. It advances the state of the art in oil and grease measurements and eliminates shortfalls associated with other solvent-based methods.
The Clearshot system consists of single use oil and grease extractors, standard Luer-Lok syringes, and a convenient portable air drying system (or house air can be used if available). Measurement is performed by simply drawing a liquid sample into the syringe, processing the sample through an extractor (by hand or with a syringe pump), drying the extractor with compressed air, and optically measuring the captured oil and grease directly through the extractor using an FTIR analyzer. Easy adoption of this method has been demonstrated in both field and laboratory settings.
The ClearShot Extraction Technology system has been optimized to work with virtually any FTIR analyzer operating in transmission mode, and has been demonstrated and used with a variety of different manufacturers instruments (Thermo/Nicolet, Shimadzu, ABB, Bruker, PerkinElmer).
Time required per sample: 15 minutes
A single operator can perform up to 20 measurement in ONE HOUR
The ClearShot system has been demonstrated to deliver accurate oil and grease measurements in a fraction of the time and cost of competing methods, allowing for high sample throughput and greatly reduced operator time. In particular, the ClearShot system and associated method (ASTM D7575) has been shown in side-by-side tests to generate comparable results to EPA Method 1664 over a range of waste and produced water matrices (POTW, petroleum plant, chemical manufacturer, meat processor, and others).
"EPA's analysis demonstrates ASTM D7575-10 is an acceptable stand-alone method for the measurement of oil in grease in wastewater for the application reporting range (5-200 mg/L) and it produces results that are generally very close to those obtained using EPA Method 1664A for the matrices tested. Second, this method has certain advantages over the currently approved method. EPA supports pollution prevention, and is particularly persuaded by the substantial advantages associated with the green aspects of this membrane technology (e.g., it uses a solventless extraction, there is no solvent waste, and no analyst exposure to solvent). Finally, ASTM D7575-10 may offer other advantages such as ease of analysis, reduced analysis time, and lower analytical costs."
