Abstract

An instrument for the continuous measurement of nitrogen dioxide (NO/sub 2/) at all atmospheric concentration ranges and conditions was developed. The detector is based on the chemiluminescent reaction between 5-amino-2,3-dihydro-1,4-phthalazinedione (luminol) and NO/sub 2/ in alkaline aqueous solution. Development included the optimization of the cell design and the solution composition. Sodium sulfite (Na/sub 2/SO/sub 3/) and methanol (CH/sub 3/OH) were added to the solution to improve sensitivity and specificity. The detector was favorably compared to two different instruments measuring NO/sub 2/ by NO + O/sub 3/ chemiluminescent and by a tunable diode laser absorption spectrometry system. The detector has demonstrated a detection limit of 30 parts-per-trillion by volume (ppt) and a frequency response of 0.3 Hz. The instrument was operated for two one-month periods on Bermuda. The purpose was to study air masses from the East Coast of the United States after transport over the ocean. Average daily values were 400 ppt with values as low as 100 ppt measured. Other field experiments involved monitoring of NO/sub 2/ in ambient air in the range of 1 to 60 parts-per-billion by volume.

Luminol-based nitrogen dioxide detector

Journal Article Wendel, G; Stedman, D; Cantrell, C; ... - Anal. Chem.; (United States)

An instrument for the continuous detection of NO/sub 2/ in the sub-part-per-billion range is described. The instrument is based upon the chemiluminescent reaction between NO/sub 2/ in air and luminol (5-amino-2,3-dihydro-1,4-phthalazinedione) in alkaline solution. The present detector exhibits a 2-Hz response speed to changes of +/-20 ppB and a field detection limit of 30 parts per trillion. The instrumental technique has been expanded to measure NO by the catalytic oxidation of NO to NO/sub 2/ using CrO/sub 3/ on silica gel as the oxidizing agent; however, at low ambient NO concentrations some drift in the NO zero is observed.

Capillary gas chromatographic analysis of nitrogen dioxide and pans with luminol chemiluminescent detection.

Journal Article Gaffney, J; Bornick, R; Chen, Y; ... - Atmos. Environ.

Peroxyacyl nitrates (PANs) and nitrogen dioxide are important atmospheric air pollutants in the troposphere. These atmospheric nitrogen species are strongly coupled chemically by a clearly temperature-dependent equilibrium in the troposphere. A chemical method that can measure both nitrogen dioxide and PANs rapidly and with sub-part-per-billion detection is described that is based upon a modified luminol detection system coupled to a capillary gas chromatographic column by using helium as a carrier. The system can readily separate and detect nitrogen dioxide, peroxyacetyl nitrate, peroxyproprionyl nitrate, and peroxybutyrl nitrate with detection limits in the low tens of parts per trillion with total analysismore »« less

Short-Time-Response measurements of nitrogen dioxide and peroxyacetyl nitrate by fast capillary gas chromatography with luminol detection.

Conference Marley, N; Gaffney, J; Drayton, P

The interaction of hydrocarbons and nitrogen oxides in sunlight to produce photochemical smog has been well studied over the years. In the past, the workhorse for the measurement of NO{sub 2}and NO was the chemiluminescent reaction with ozone. This method has detection limits of approximately 0.5 ppb in most commercial instruments, but it cannot detect NO{sub 2} directly; the instrument detects NO and uses hot catalytic surfaces to decompose all other nitrogen oxides (including NO{sub 2}) to NO for detection (l). The main problem with the method is the inherent difficulty in detecting excited NO{sub 2}, which emits over amore »« less

Fast gas chromotography with luminol detection for measurement of nitrogen dioxide and PANs.

Conference Gaffney, J; Marley, N; Drayton, P

Fast capillary gas chromatography has been coupled to a luminol-based chemiluminescence detection system for the rapid monitoring of nitrogen dioxide and peroxyacyl nitrates. A first-generation instrument was described recently (Gaffney et al., 1998). This system is capable of monitoring nitrogen dioxide and peroxyacyl nitrates (PANs; to and including the C4 species) with 1-min time resolution. This is an improvement by a factor of five over gas chromatography methods with electron capture detection. In addition, the luminol method is substantially less expensive than laser fluorescent detection or mass spectroscopic methods. Applications in aircraft-based research have been published electronically and will appearmore »« less

Capillary gas chromatographic analysis of pans with luminol chemilumnescent detection

Conference Gaffney, J; Bornick, R; Chen, Yu-Harn; ...

Peroxyacyl nitrates (PANs) are important air pollutants in tropospheric chemistry. PANs are known to be potent phytotoxins at low ppb concentrations and are lachrymators. They can also transport the more reactive nitrogen dioxide long distances, because they are in equilibrium with that NO{sub x} species. Since PANs are trapped peroxyradicals, they are a direct measure of the peroxyradical levels and the of {open_quotes}photochemical age{close_quotes} of an air parcel. The PANs are typically measured in the atmosphere by using electron capture detection methods. These methods suffer from large background signals and detector responses to oxygen and water vapor.
