AMBIENT PARTICLE LOSSES IN THE SK SAMPLING SYSTEM.
(NILU TR;14/83, Research report, 1983)The SK sampling system (filter mounted after sampling line and manifold) has been compared to an open-face filter holder mounted outside. The SK system undersamples ambient aerosols due to sampling line losses. Aerosol ... -

FLOW RATE CALIBRATION OF HIGH VOLUME SAMPLERS
(NILU TN;4/81, Research report, 1981)Primary (using a Rootsmeter) and secondary (using an orifice calibration unit) calibration methods for the us EPA-type "high-volume" suspended particulate sampler are described. -

MEASUREMENT OF SULPHUR DIOXIDE IN THE PPB RANGE.
(NILU TR; 12/84, Research report, 1984)A commercial continuous SO2-monitor from Philips (based on a coulometric principle) was modified. A detection limit of 1 µg S02/m3 (S/N 2:1) was obtained. Stability and selectivity aspects are discussed. -
REBUILT PHILLIPS SO2-MONITOR ON MOBILE PLATFORM.
(NILU TR;7/85, Research report, 1985)Philips S02 monitors have previously been modified for measurements in the ppb-range. New modifications allow mobile operation. Vibrations increase the noise signal, and the detection limit increases from 1 µg/m3 to 3 ... -
