If this is not possible, the samples should be further preserved by e.g. freezing, if possible, to minimize biodegradation and loss of volatile halogenated and sulfur compounds. The test sample is prepared according to EN 15002. For solid materials, the particle size should be less than 200 µm. During preparation of the test sample, the use of halogenated polymers, e.g. PVC gloves, should be avoided. Drying the laboratory sample may be carried out for homogenization purposes if the sample, according to the accuracy of the method, contains only negligible amounts of halogen and sulfur compounds volatile at the temperature intended for the drying process. Dry matter is determined according to EN 14346 on a separate sub sample (the result will be used for calculation). Heterogeneous moist or paste like samples may be mixed with aluminium oxide (7.1.10) until granular material is obtained and then reduced to a granular powder, preferably with a particle size less than 200 µm. In this case, the ratio of aluminium oxide to sample should be incorporated into the calculation of the halogen and sulfur content and combustion enhancer should be added if necessary.

NOTE 2 The ascorbic acid and large amount of nitrate may interfere with early eluting halogens (fluoride, chloride and bromide) if detected by ion chromatography. The determination of recoveries of halogen and sulfur from control mixtures mentioned in Table 1 is presented in Annex C, in order to show the possible use and combination between absorption solutions and different analytical methods. 10.3 Preparation of the bomb The bomb is prepared according to the manufacturer’s instructions and the free ends of the firing wire (9.3) attached to the electric terminals of the ignition circuit (9.4). If using an absorption solution inside the bomb, add 10 ml of the chosen absorption solution (see 10.2), wetting the sides of the bomb (9.1). The sample cup should not be in contact with the absorption solution. Depending on the bomb design and/or the expected concentration range of the analytes of interest, it may be necessary to adapt the amount of the absorption solution or trap the combustion gases in an external absorption flask (see 9.5). 10.4 Combustion 0,05 g to 1 g of sample, depending on its calorific value, the amount of element present and on the determination method, is weighed (to the nearest 0,1 mg) into the sample cup (9.2). Samples that burn with difficulty (e.g. mineral samples or samples with high water content), may require the addition of a combustion enhancer (7.1.9). Liquid samples may be weighed in a capsule (7.1.11). To avoid swirling up of the sample when filling the bomb with oxygen, powdery samples may be covered with inert material (e.g. aluminium oxide (7.1.10)) or soaked with combustion enhancer (7.1.9), depending of their calorific value. Powdery samples with low density and that burn very readily may be pressed into a pellet before combustion, to avoid material to be flung out of the crucible. Depending on the type of the bomb, the total sample mass plus enhancer should not exceed 1 g to 1,5 g to avoid dangerous high pressure and possible rupturing the bomb. NOTE 1 The combined energy from sample and enhancer is not important to recover halogens and sulfur from the sample compounds. Hence it may be necessary to optimize the enhancer/sample amount ratio. Place the sample cup in position and arrange the firing wire (9.3) so that it will be just in contact with the sample but not touching the sample cup (9.2). SIST EN 14582:2017
