NOTE Alternatively, inductively coupled plasma mass spectrometry (ICP-MS) can be used for the measurement if the user proves that the method gives the same results. This method is applicable to aqua regia digests prepared according to CEN\/TS 17768 for the determination of P, K, Ca, Mg, Na, S, B, Co, Cu, Fe, Mn, Mo, Zn, As, Cd, Cr, Ni, Pb by ICP-AES. The method can be used for the determination of other elements, provided the user has verified the applicability.<\/p>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>undefined  <\/td>\n<\/tr>\n<tr>\n<td><b>7<b><\/td>\n<td>1 Scope <br \/> 2 Normative references <br \/> 3 Terms and definitions <br \/> 4 Principle <br \/> 5 Interferences <br \/> 5.1 General <br \/> 5.2 Spectral interferences  <\/td>\n<\/tr>\n<tr>\n<td><b>8<b><\/td>\n<td>5.3 Transport interferences <br \/> 5.4 Excitation interferences <br \/> 5.5 Chemical interferences <br \/> 5.6 Memory interferences <br \/> 6 Reagents <br \/> 6.1 General <br \/> 6.2 Nitric acid, substance concentration c(HNO3) \u2248 14,3 mol\/l; mass concentration \u03c1 \u2248 1,4 g\/ml. <br \/> 6.2.1 Diluted nitric acid solution, c(HNO3) = 5 mol\/l.  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>6.3 Hydrochloric acid, c(HCl) \u2248 12 mol\/l; \u03c1 \u2248 1,18 g\/ml. <br \/> 6.4 Mixed acid solution, 0,8 mol\/l nitric acid and 1,8 mol\/l hydrochloric acid. <br \/> 6.5 Standard stock solutions, concentration of 1 000 mg\/l for each element. <br \/> 6.5.1 General <br \/> 6.5.2 Standard solution, concentration of 100 mg\/l of element. <br \/> 6.5.3 Standard solution, concentration of 10 mg\/l of element. <br \/> 6.6 Argon, purity 99,995 % or better. <br \/> 7 Apparatus <br \/> 7.1 Common laboratory glassware. <br \/> 7.2 Inductively coupled plasma atomic emission spectrometer.  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>8 Procedure <br \/> 8.1 Preparation of test and blank solution <br \/> 8.2 Preparation of the calibration solutions <br \/> 8.3 Measurement <br \/> 8.3.1 Instrument conditions  <\/td>\n<\/tr>\n<tr>\n<td><b>11<b><\/td>\n<td>8.3.2 Optimization of the instrument conditions <br \/> 8.3.3 Interferences <br \/> 8.3.4 Matrix effects <br \/> 8.3.5 Spiking  <\/td>\n<\/tr>\n<tr>\n<td><b>12<b><\/td>\n<td>9 Calculation and expression of the results  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>10 Test report  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Organic and organo-mineral fertilizers.
