Portable IR Analyzer measures soot percent in diesel engines oil.

Press Release Summary:

Portable IR Analyzer measures soot percent in diesel engines oil.

February 15, 2013 - Via field spectroscopic check, InfraCal Soot Meter gives users approved ASTM testing method for measuring percent level of soot in diesel engine lubricating oils per ASTM Method D7686. Portable, filter-based IR analyzer is factory calibrated for measuring soot percent levels up to 12%–15% in under 30 sec without requiring sample preparation, dilution, solvents, or transmission cells. Sealed against accidental spills, analyzer has no moving parts.

Portable IR Analyzer Provides ASTM Field Test Method

Press release date: February 12, 2013

The InfraCal Soot Meter, from Wilks Enterprise, gives users an approved ASTM testing method for measuring the percent level of soot in diesel engine lubricating oils -- ASTM Method D7686 entitled “Test Method for Field-Based Condition Monitoring of Soot in In-Service Lubricants Using a Fixed-Filter Infrared (IR) instrument.”

While there is widespread disagreement on used-diesel oil condemning limits, it is well known that excessive soot in the lube oil causes abnormal valve and injection-train wear.  It can also increase exhaust emissions and clog filters.  Typically, the suggested limit for soot is in the neighborhood of 3% but can go higher. This ASTM Method gives truck, bus, ship, locomotive, and off-highway equipment fleet operators, power generation plants, as well as used oil labs and engine test facilities, an easy, on-site analysis method that accurately measures soot percent levels in under 30 seconds – without sample preparation, dilution, solvents, or messy transmission cells to clean.

This ASTM test method for field-based condition monitoring of soot in in-service lubricants uses the InfraCal Soot Meter which is a filter-based infrared analyzer.  The Soot Meter is factory calibrated for measuring levels up to 12%-15% and provides a fast, simple field spectroscopic check for helping to diagnose the operational condition of the diesel engine in less than 30 seconds.

The InfraCal Soot Meter is portable, weighs less than 5 pounds, and is roughly a 6 inch cube in size. Its rugged construction which is sealed against accidental spills, plus no moving parts, makes it the perfect instrument for field-based operation and easily operated by non-technical personnel.  However, it can easily be used in the lab to free-up an FTIR spectrometer for more complex analyses.  It is also relatively low-cost when compared to more sophisticated and time-consuming analytical instrumentation such as FTIR or thermogravimetric analysis (TGA).  Analyzing a used oil sample with the InfraCal Soot Meter takes only a couple of quick steps – apply a sample to the built-in ATR crystal, push the run button, and the percent soot is displayed in seconds.
