Inductively Coupled Plasma-Mass Spectrometry (ICP-MS): Interferences01:20

Inductively Coupled Plasma-Mass Spectrometry (ICP-MS): Interferences

1.7K
Inductively coupled plasma–mass spectrometry (ICP–MS) is a highly selective and sensitive technique for accurate elemental analysis. Though the analysis of ICP–MS mass spectra is comparatively straightforward, it is affected by spectroscopic and non-spectroscopic interferences. Spectroscopic interferences arise when the plasma contains ionic species with an m/z value the same as the analyte ion. Spectroscopic interference can be categorized as isobaric, polyatomic ions, and...

Inductively Coupled Plasma–Mass Spectrometry (ICP–MS): Overview

2.7K
In inductively coupled plasma–mass spectrometry (ICP–MS), an inductively coupled plasma (ICP) torch is used as an atomizer and ionizer. Solid samples are dissolved and volatilized before being introduced into the high-temperature argon plasma, while solution samples are nebulized and passed through the high-temperature argon plasma. Plasma dissociates the analytes and ionizes their component atoms to form a mixture of positive ions and molecular species. The positive ions are then...

Area of Science:

  • Food Science
  • Analytical Chemistry
  • Environmental Health

Background:

  • Trace elements are naturally present in cocoa beans and can be introduced during processing.
  • Understanding trace element levels in chocolate is crucial for food safety and consumer health.

Purpose of the Study:

  • To quantify eight trace elements (lead, cadmium, chromium, manganese, cobalt, arsenic, bismuth, molybdenum) in chocolate and cocoa products.
  • To investigate the relationship between trace element concentrations and cocoa solids content.
  • To assess potential health risks associated with trace element intake from chocolate, particularly for children.

Main Methods:

  • Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was used for trace element analysis.
  • Samples underwent digestion and filtration to remove lipids.
  • Indium was employed as an internal standard to mitigate matrix effects.

Main Results:

  • A linear correlation was observed between cocoa solids content and the levels of several trace elements in chocolate.
  • Significant concentrations of bismuth (Bi) and arsenic (As) were detected in cocoa bean shells, but not in beans or chocolate, suggesting environmental contamination.
  • Other elements were primarily linked to manufacturing processes.

Conclusions:

  • Children consuming chocolate may be at risk of exceeding the daily oral lead intake limit.
  • Adults generally face minimal risk from trace metal ingestion due to lower digestive absorption rates.
  • Cocoa bean shells can accumulate environmental contaminants like arsenic and bismuth.
