UV-VIS Spectrometer TT-1840
UV-VIS Spectrometer TT-1840 adheres to the ASTM D1840 Standard Test Method for Naphthalene Hydrocarbons in Aviation Turbine Fuels by Ultraviolet Spectrophotometry.
This testing procedure for naphthalene hydrocarbons is part of a set of tests used to evaluate the combustion properties of aviation turbine fuels within the kerosene boiling range. The determination of naphthalene hydrocarbon content is crucial because naphthalenes, upon combustion, tend to contribute more significantly to a sooty flame, smoke, and thermal radiation compared to single-ring aromatics.
The primary application of this spectrometer is to determine the content of naphthalene hydrocarbons in aviation turbine fuels, in compliance with the ASTM D1840 standard. This is essential for evaluating the combustion properties of the fuel.
Due to its versatile technology, the spectrometer is also suitable for a broad range of other fields, including:
- Biological research
