SAMPLING METHOD FOR VOLATILE ORGANIC COMPOUNDS (SMVOC)

1.8 The SMVOC is designed to be operated at a sampling rate of 1 L/min with traps being replac ed every 20 min for a total sampling time of 2 hrs. Analysis of the traps is carried out b y thermal desorption purge-and-trap gas chroma tography/mass spectrometry (see Methods 5041 and 8260).

METHOD 1030 IGNITABILITY OF SOLIDS

6.4 A Bunsen (propane gas and air) burner with a minimum diameter of 5 mm capable of attaining a temperature of at least 1,000 oC. 6.5 Stop watch. 6.6 Thermocouple to measure the temperature of the gas flame. 6.7 Thermometer to measure initial temperature of material (i.e., room temperature). 6.8 Anemometer to measure airflow in the fume hood.
