Measurement and Testing
Portable IR Analyser Measures Soot Levels in Diesel Engine Oils Without Sample Preparation
Extended drain times, combined with stringent emission requirements, make it important to routinely check the soot levels in diesel engine lubricating oil. Rapid, on-site field measurement of soot concentration levels in diesel engine oils at levels as high as 12 - 15% takes less than 30 seconds with the InfraCal Soot Meter
available from Wilks Enterprise (USA). This compact, pushbutton analyser provides direct readout of the percent of suspended carbon (soot) in diesel engine lubricating oils without sample preparation, dilution, or solvents and messy transmission cells to clean. Currently, an ASTM Method covering the InfraCal Soot Meter entitled, "Condition Monitoring of Soot in In-Service Petroleum and Hydrocarbon-Based Lubricants Using a Fixed-Filter Infrared (IR) Instrument", is pending.
Since the InfraCal Soot Meter was specifically designed for easy, on-site testing, it represents a major time savings from the widely-used and accepted thermogravimetric analysis (TGA) and FT-IR methods that are impractical as field analysis methods. The measurement data obtained from the Soot Meter will correlate to TGA and FT-IR analysis techniques with several distinct advantages. Analysis time with the InfraCal Soot Meter is less than 30 seconds per sample with direct readout of soot levels as high as 12 – 15% without sample dilution or transmission cells to clean. The Soot Meter is significantly lower in cost and one step, pushbutton operation makes it easy to use with minimal operator training.
A rugged, no-moving parts design ensures years of virtually maintenance-free operation with the InfraCal Soot Meter. Weighing less than 5 lbs., it operates off 12 volt d.c. power and is ideal for use along side diesel engines for on-site, field measurements, in the used oil/engine testing laboratory, at power generation stations, or for truck, bus, and off-highway equipment fleets. The InfraCal Soot Meter is Ideal for use on all types of diesel lubricating oils and engines.

New 5-year Warranty for Pressure Gauges and Termometers
Analysing VOC’s in Water
Chromatotec (France) is pleased to announce a new analyser system for the surveillance of VOCs in water, which is named airmoPURGE.
The sample preparation technique is based on US EPA method 502.2 for purging the VOCs from water using an inert gas, followed by their analysis using our certified airmoVOC C6-C12 analyser.
There are many applications for this technique including the analysis of raw source water, seawater, rain water and also for the analysis of finished drinking water. Headspace analysis is available for analysis of wastewater.
It should be noted that the analysis system used in this application can also optionally measure VOCs in ambient air i.e. the concentrations of VOCs in both air and water can be measured using this one single system!

New Solar Powered Industrial Termometer
Dwyer Instruments, Inc., (USA) is announcing the release of its new Series SIT solar powered industrial thermometer.
The Series SIT solar powered industrial thermometer accurately measures temperature with no batteries or power cables. For the best possible viewing angle, the stem can be adjusted 180° in the vertical plane and the display housing can be adjusted 180° in the horizontal plane providing a full 360° rotation. Engineering units are field selectable with an external dip switch enabling the thermometer to read from -50 to 300°F or -45 to 150°C. In addition, the large 1/2˝ digit display allows measurements to be easily read across the room. Rated as low as 10 lux, the Series SIT solar thermometer is excellent for reading in low light applications.

P S Analytical (UK) continues to focus its attention both on the application of its products for determining mercury and also on the more fundamental aspects of the science. Applications for petrochemical analysis for mercury levels remain of significant interest, mercury, even at low ppt levels creates significant risks to the processing of petrochemical products. In all fractions of the petrochemical product range, including natural gas, liquefied natural gas and liquid condensates, mercury levels need to be monitored and the mercury removed where necessary and possible.
Working closely with industry and regulators, P S Analytical has installed fully automated systems that meet international safety standards and provide continuous measurements of the mercury levels in the sample streams. Tailoring systems and chemistries to customer requirements and site practicalities has put PSA firmly at the forefront of this analysis.
P S Analytical’s Atomic Fluorescence Spectrometers also have applications for the measurement of arsenic. In many petrochemical areas arsenic presents its own problems, especially as it can significantly poison catalytical reactions used in the industry. Working alongside customers, P S Analytical has developed process applications to determine arsenic levels in these products accurately and reliably.
