ASTM D1840 UV-VIS Spectrometer

KN-1840 UV-VIS Spectrometer

Overview

    KN-1840 UV-VIS Spectrometer conforms to ASTM D1840 Standard Test Method for Naphthalene Hydrocarbons in Aviation Turbine Fuels by Ultraviolet Spectrophotometry. This test method for naphthalene hydrocarbons is one of a group of tests used to assess the combustion characteristics of aviation turbine fuels of the kerosene boiling range. The naphthalene hydrocarbon content is determined because naphthalenes, when burned, tend to have relatively larger contribution to a sooty flame, smoke, and thermal radiation than single ring aromatics.
