| Test Method A sample of soil is extracted with isopropyl alcohol, and the extract is filtered. The ultraviolet absorbance of the extract is measured at 254 nm. If the contaminant fuel is available for calibration, the approximate concentration of contamination is calculated. If the contaminant fuel type is known, but the contaminant fuel is not available for calibration, an estimate of the contaminant concentration is determined using average response factors. If the nature of the contaminant fuel is not known, the absorbance value is used to indicate the presence or absence of fuel contamination. Calcium oxide is added to the soil as a conditioning agent to minimize interferences from humid materials and moisture present in the soil. Particulate interferences are removed by passing the extract through a filter. Features and Benefits • Utilizes ultraviolet photometer for detection of heavier fuels • Works with wet or dry soils • Provides accurate test results regardless of operating temperature • Self-contained portable kit |
| K47150 Diesel Dog Test Kit The Diesel Dog Soil Test Kit combines advanced technology with a new method to detect and measure fuel contamination in soils, bringing you an easy, safe and economical way to analyze samples in the field. The simple testing procedure utilizes isopropyl alcohol rather than ozone-depleting chlorofluorocarbons for soil extraction. The extract is then placed in the photometer and measures the concentration of the fuel at 254nm. The Diesel Dog Soil Test Kit is specially designed to test for heavier fuels. It uses a new method approved by ASTM making it useful for federal compliance activities. The Diesel Dog Soil Test Kit can be used by anyone who needs to map ground contamination or guide cleanup activities, such as environmental contractors, consultants, and laboratories conducting field analyses. Other users are gas and electric utilities, emergency response teams, and environmental agencies. The kit is designed and constructed for use in tank farms, refineries, oil production fields, railroad yards, manufactured gas sites, automotive salvage yards, and underground storage and heating oil tank sites. Specifications Conforms to the specifications of: ASTM D583 |
