Ultraviolet spectrometer measures pure monochromatic wavelengths in predetermined narrow wave bands. Two stages are incorporated: stationary dispersed beam is intercepted by array of slits cut into plate at discrete wavelength locations; second stage is inverted spectrometer which recombines dispersed spectrum at single exit slit.

An Aerodyne Aerosol Mass Spectrometer (AMS) was deployed during the Aerosol Characterization Experiment-Asia (ACE-Asia) field campaign on board the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) Twin Otter aircraft to measure the size- resolved chemical composition of sub-micron aerosols in the outflow from Eastern Asia. Research flights were carried out from March 31-May 1, 2001 in an area that covered 127 °E-135 °E and 32 °N-38 °N. Valid data from the AMS were obtained during 15 out of a total of 19 research flights. During the mission, the AMS measured distinct layers (from the boundary layer to ~ 3700 m) of sub-micron aerosols composed of sulfate, ammonium, and organics as the major non-refractory components, separated by layers with much lower aerosol concentrations. Sulfate and organics mass concentrations of up to 10 µg m-3 and 13 µg m-3, respectively, were measured in some pollution layers. Back trajectory analysis shows that the polluted layers originated in urban and industrial areas of China and Korea. The mass-weighed size distribution of the sub-micron sulfate was relatively constant from day to day and layer to layer, with an

This instrument was utilized by the old "Sugar" section of the National Bureau of Standards, to determine the color of sugar. It was the instrument used as the forerunner of the present day spectrophotometry methods of testing both sugar and petroleum. This instrument was acquired by NBS in 1975.
