8、s for determination of acrolein in flue gas 1 Scope This Japanese Industrial Standard specifies methods for determination of acrolein (acrylaldehyde) in flue gas. Remarks i In this Standard, flue gas means ones which are generated by being ac- companied with works for production or use of acrolein i

16、ypical gas is collected, for example the point where the flow rate of gas does not remarkably change. Sampling position os gas 4.2 Classification of sampling methods There are two types of method. One is for 1 1 or under (vacuum collecting bottle method) and the other for approx. 20 1 (absorption bo
17、ttle method). 4.3 When sampling gas volume is 1 1 or under This method shall be applied for the gas chromatography. 4.3.1 Vacuum collecting bottle The vacuum collecting bottle, as shown in Fig. 4 (b-2) of JIS K 0095, which is 1 I of inner capacity with a fluoride resin valve requiring no grease and
18、with a silicone rubber plug (l). Note (l) The inside of the bottle shall be washed previously with a detergent. When low temperature concentration method is employed, inner volume of the bottle shall be measured. 4.3.2 Sampling of gas Before sampling of the gas, air in the vacuum collecting bottle s
19、hall be evacuated. When sampling of gas is carried out, open the valves of the bottle and introduce the sample gas from the gas sampling tube (Approx. 2 mm to 3 mm inner diameter ) through a dehumidification tube (). Note (9 Temperatures of atmosphere and flue gas shall be measured prelimi- narily.
20、Those data can be used when the correction is required. Except where the flue gas temperature is remarkably high, atmospheric tem- perature may use as the temperature of sample gas at the time of Sam- pling. 4.4 When sampling gas volume is approx. 20 1 Hexylresorcinol absorptiometry. This method sha
