WARNING — Persons using this European Standard should be familiar with usual laboratory practice. The reagents used in this European Standard are strongly corrosive and partly very toxic. Safety precautions are absolutely necessary, not only due to the strong corrosive reagents, but also to high temperature and high pressure.
The use of laboratory-grade microwave equipment with isolated and corrosion resistant safety devices is required. Domestic (kitchen) type microwave ovens shall not be used, as corrosion by acid vapours may compromise the function of the safety devices and prevent the microwave magnetron from shutting off when the door is open, which could result in operator exposure to microwave energy.
All procedures shall be performed in a fume hood or in closed force-ventilated equipment. By the use of strong oxidising reagents, the formation of explosive organic intermediates is possible, especially when dealing with samples with a high organic content. Do not open pressurized vessels before they have cooled down. Avoid contact with the chemicals and the gaseous reaction products.
IMPORTANT — It is absolutely essential that tests conducted according to this European Standard be carried out by suitably trained staff. SIST EN 16173:2013

Digestion with nitric acid will not necessarily accomplish total decomposition of the sample. The extracted analyte concentrations may not necessarily reflect the total content in the sample. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 16179, Sludge, treated biowaste and soil — Guidance for sample pretreatment EN ISO 3696, Water for analytical laboratory use — Specification and test methods (ISO 3696) 3 Principle A test portion is digested in concentrated nitric acid by means of microwave heating with a suitable laboratory microwave unit. The sample and the nitric acid are placed in a fluorocarbon polymer or quartz microwave vessel. The vessel is sealed and heated in the microwave unit. After cooling, the vessel contents are filtered, centrifuged or allowed to settle and the clear solution is then transferred into a volumetric flask and diluted to volume and analysed by the appropriate measurement method. 4 Interferences and sources of errors Due to the volatility of some compounds care shall be taken that the sample is not heated before the digestion and that any volatile reaction products formed during the digestion do not escape. The container in which the sample is delivered and stored can be a source of errors. The material shall be chosen according to the elements to be determined; e.g. elemental Hg can penetrate polyethylene walls very fast in both directions. Glass containing e.g. B, Na, K, Al can contaminate samples. A few refractory sample matrix constituents, such as quartz, silicates, titanium dioxide, alumina and other oxides may not be dissolved. The bound elements are considered non-mobile in the environment and are excluded from most aquatic pollution transport mechanisms. High acid and solute concentrations in the digest that cause interferences shall be properly addressed during determination. SIST EN 16173:2013
If the digested solution is filtrated, take care that the filtration procedure does not introduce contamination. 5 Reagents Use only acids and reagents of recognized analytical grade to avoid high blank values for subsequent analytical measurements. Use a test blank solution throughout the procedure applying all steps with the same amount of acids, but without a sample. 5.1 Water, grade 2 as specified in EN ISO 3696 or better. The water for preparation of reagents shall meet the requirements of the subsequent analysis. Verify the purity by performing a blank test. 5.2 Nitric acid, c(HNO3) = 15 mol/l, ρ = 1,4 kg/l. 5.3 Nitric acid, c(HNO3) = 0,5 mol/l; ρ = 1,0 kg/l. 6 Apparatus Usual laboratory apparatus. All glassware and plastics ware shall be adequately cleaned and stored in order to avoid any contamination. Depending on the concentration of the element of interest, a particular caution to the cleaning of the vessels shall be taken. 6.1 Microwave digestion system, corrosion resistant and well ventilated. All electronics shall be protected against corrosion for safe operation. Use a laboratory-grade microwave oven with temperature feedback control mechanisms. The microwave digestion system should be able to control the temperature with an accuracy of ± 5 °C and automatically adjust the microwave field output power within 2 s of sensing. Temperature sensors shall be accurate to ± 2 °C, including the final reaction temperature of (175 ± 5) °C. Temperature feedback control provides the primary performance mechanism for the method. Due to the variability in sample matrix types and microwave digestion equipment (i.e. different vessel types and microwave designs), control of the temperature during digestion is important for reproducible microwave heating and comparable data. The accuracy of the temperature measurement system should be periodically controlled at an elevated temperature according to the manufactures instructions. If the temperature deviates by more than 2 °C from the temperature measured by an external, calibrated temperature measurement system, the microwave temperature measurement system should be calibrated. 6.2 Rotating turntable, with a minimum speed of 3 min–1.
