Analysis of Trace Elements in Table Salt Using ICPMS-2050

User Benefits

- Elements in table salt can be accurately analyzed over a long period of time. - Reduced running costs due to a mini-torch that uses less argon gas - Avoids a complex investigation of conditions by using the analytical conditions from preset methods.

Introduction

The Codex general standard for contaminants and toxins in food and feed (Codex) establishes requirements for levels of toxic metal elements in foods. Inductively coupled plasma mass spectrometry (ICP-MS) systems can perform highly sensitive quantitative determination of multiple elements simultaneously, making them suited to the analysis of even trace amounts of toxic metal elements in foods. Food samples are typically high-matrix samples that can often impact the clogging of torch or interfaces such as skimmer cone, non-spectral interference, and long-term stability in ICP- MS analysis. This Application News uses the ICPMS-2050 to analyze table salt, a food with a particularly high matrix concentration. This analysis was performed using a mini-torch that features low argon gas consumption. The long-term stability and spike recovery were assessed based on the Food and Drug Administration (FDA) Elemental Analysis Manual (EAM) Section 4.7.
