How Our ClearShot™ Technology Works

ClearShot Extraction Technology Accurately, Safely and Quickly Measures Extremely Low Non-volatile Residual Oil Concentrations in Critical Applications

In a wide range of applications, oils are used as part of the process to achieve the desired end product functionality.  Once that process has been completed, all oil must then be removed with the use of solvents.  In these processes, any remaining oil can result in catastrophic disaster from significant equipment damage to loss of human life.  Traditionally, it has been challenging to confirm that all oil has been properly removed.  OSS has developed ClearShot systems, based on the specific characteristics of the oils and solvents, that can be used to quickly, accurately, precisely and cost effectively determine the concentration of any remaining oils in the cleaning solvents.

Challenges of Traditional Methods

Oil remaining in solvent-based systems or on the surfaces of parts can create product quality and product performance issues as well as potentially dangerous situations. Measuring that residual oil has traditionally relied on methods ranging from complex processes that use dangerous solvents for extracting oils to visual inspections that are problematic due to limited visibility. These methods can be complex to perform, time consuming, and more importantly, may not provide an accurate measurement of residual oil concentration. As a result, more time and excess money may be spent on additional cleaning and solvent extractions to ensure that no oil remains. OSS has developed a simple, easy to use residual oil measurement method that quickly provides key information required to make these manufacturing and quality control decisions.

Advantages of our ClearShot Method

  • High level of Test Accuracy and Precision at Low Concentrations
  • Simple Method with a Few Straightforward Steps
  • Cost Saving Alternative to Other Methods
  • Minimizes Risks Based on Immediate Results
  • Method is Designed to Fit Any Application Needs
  • Technology is Not Impacted by Changes in System Cleaning Solvent

Residual Oil Measurement Method

The OSS ClearShot Residual Oil in Solvent Detection Methods generally have four main steps:

  • Obtain a small representative sample of the cleaning solvent
  • Process a specific volume into a uniquely designed ClearShot extractor
  • Remove the solvent from the extractor
  • Measure oil concentration using an FTIR unit

Residual Oil Sample Spectra

The FTIR spectra data to the left has been constructed using Heavy Mineral Oil in a solvent system.  The data shows that the method can accurately measure and distinguish between different  concentration levels.  Using macros and software designed specifically for these applications, the technician will simply follow the prompts and the system will automatically generate the oil concentration level result.

Oil Identification

Identify the Source

OSS Clearshot technology, in combination with FTIR capabilities, can be used to create individual oil product “fingerprint” catalogues. These individual unique characteristics of different oils are used to automatically identify which oils are present in the sample being analyzed, with no additional steps required.

Prevent Quality Issues

OSS will work with your team to identify the oil products in samples being analyzed. In production facilities, you can quickly identify the source of an oil problem and take immediate action. Knowing the source can prevent poor process performance, substandard product quality, and costly fines.
