Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard is proposed and managed by the National Certification and Accreditation Administration Committee. This standard was drafted. People's Republic of China Jiangsu Entry-Exit Inspection and Quarantine Bureau. The main drafters of this standard. a new kingdom, Xu Yuyu, Wang Hui, Liu Feng, Wu Guangyu, Zhu Jiayu. Stainless steel, manganese, phosphorus, silicon, chromium, nickel, copper, molybdenum and titanium Inductively coupled plasma atomic content Emission Spectrometry

1 Scope

This standard specifies the inductively coupled plasma atomic stainless steel manganese, phosphorus, silicon, chromium, nickel, copper, molybdenum and titanium emission spectrometer method. This standard applies to the determination of carbon content of not more than 0.20% of the stainless steel manganese, phosphorus, silicon, chromium, nickel, copper, molybdenum and titanium content. Measurement Table 1 given range. The silicon standard assay for soluble silicon.

3 Method summary

Samples with hydrochloric acid - nitric acid mixture dissolved, yttrium internal standard element After cooling, diluted to determine the volume of the sample solution is introduced into the plasma Atomic emission spectrometer to measure the wavelength corresponding elements in its emission intensity, measured by elemental analysis to calculate emission intensity line and the internal standard line emission intensity The ratio of the degree, according to the standard curve to determine the amount of analyte.
