Ammonia Permeation device. Similar to system described in references 1 and 2 Indophenol method, reference 3.
Carbon dioxide Cylinder of zero air or nitrogen containing CO2 as required to obtain the concentration specified in table B-3 Use NIST-certified standards whenever possible. If NIST standards are not available, obtain 2 standards from independent sources which agree within 2 percent, or obtain one standard and submit it to an independent laboratory for analysis, which must agree within 2 percent of the supplier's nominal analysis.
Carbon monoxide Cylinder of zero air or nitrogen containing CO as required to obtain the concentration specified in table B-3 Use an FRM CO analyzer as described in reference 8.
Ethane Cylinder of zero air or nitrogen containing ethane as required to obtain the concentration specified in table B-3 Gas chromatography, ASTM D2820, reference 10. Use NIST-traceable gaseous methane or propane standards for calibration.
Ethylene Cylinder of pre-purified nitrogen containing ethylene as required to obtain the concentration specified in table B-3 Do.
Hydrogen chloride Cylinder 1 of pre-purified nitrogen containing approximately 100 ppm of gaseous HCl. Dilute with zero air to concentration specified in table B-3 Collect samples in bubbler containing distilled water and analyze by the mercuric thiocyanate method, ASTM (D612), p. 29, reference 4.
Hydrogen sulfide Permeation device system described in references 1 and 2 Tentative method of analysis for H2S content of the atmosphere, p. 426, reference 5.
Methane Cylinder of zero air containing methane as required to obtain the concentration specified in table B-3 Gas chromatography ASTM D2820, reference 10. Use NIST-traceable methane standards for calibration.
Nitric oxide Cylinder 1 of pre-purified nitrogen containing approximately 100 ppm NO. Dilute with zero air to required concentration Gas phase titration as described in reference 6, section 7.1.
Nitrogen dioxide 1. Gas phase titration as described in reference 62. Permeation device, similar to system described in reference 6 1. Use an FRM NO2 analyzer calibrated with a gravimetrically calibrated permeation device.2. Use an FRM NO2 analyzer calibrated by gas-phase titration as described in reference 6.
Ozone Calibrated ozone generator as described in reference 9 Use an FEM ozone analyzer calibrated as described in reference 9.
Sulfur dioxide 1. Permeation device as described in references 1 and 22. Dynamic dilution of a cylinder containing approximately 100 ppm SO2 as described in Reference 7 Use an SO2 FRM or FEM analyzer as described in reference 7.
Water Pass zero air through distilled water at a fixed known temperature between 20° and 30 °C such that the air stream becomes saturated. Dilute with zero air to concentration specified in table B-3 Measure relative humidity by means of a dew-point indicator, calibrated electrolytic or piezo electric hygrometer, or wet/dry bulb thermometer.
Xylene Cylinder of pre-purified nitrogen containing 100 ppm xylene. Dilute with zero air to concentration specified in table B-3 Use NIST-certified standards whenever possible. If NIST standards are not available, obtain 2 standards from independent sources which agree within 2 percent, or obtain one standard and submit it to an independent laboratory for analysis, which must agree within 2 percent of the supplier's nominal analysis.
Zero air 1. Ambient air purified by appropriate scrubbers or other devices such that it is free of contaminants likely to cause a detectable response on the analyzer2. Cylinder of compressed zero air certified by the supplier or an independent laboratory to be free of contaminants likely to cause a detectable response on the analyzer
