摘要

本文报告了一种用于电感耦合等离子体质谱法的不锈钢样品制备的改进方法。使用含盐酸的消解剂的传统消解方法会影响氯光谱干扰，如 35Cl16O+ 或 40Ar35Cl+。另外，使用硝酸和氢氟酸混合酸的微波消解法可以完全消除这些干扰。建议的程序有助于使用低分辨率四极杆质谱仪更可靠地定量不锈钢样品中的钛、钒、砷、铌、锡和锑。

Chlorine-free Microwave Digestion of Stainless Steel for Inductively Coupled Plasma Mass Spectrometric Analysis

This paper reports an improved method for sample preparation of a stainless steel sample for inductively coupled plasma mass spectrometry. Conventional digestion methods using a digestion agent containing hydrochloric acid affect chlorine spectral interference such as that by ³⁵Cl¹⁶O⁺ or ⁴⁰Ar³⁵Cl⁺. Alternatively, a microwave digestion method using an acid mixture of nitric acid and hydrofluoric acid can fully eliminate these interferences. The suggested procedure can contribute to more reliable quantification of titanium, vanadium, arsenic, niobium, tin, and antimony in stainless steel samples using a low-resolution quadrupole mass spectrometer.
