Inductively Coupled Plasma–Mass Spectrometry (ICP–MS): Overview01:19

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

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 passed on to...

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

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 refractory oxide ion...
Atomic Absorption Spectroscopy: Lab01:21

Atomic Absorption Spectroscopy: Lab

For AAS measurements, samples must be introduced as clear solutions, often requiring extensive preliminary treatment to dissolve materials like soils, animal tissues, and minerals. Common methods for sample preparation include treatment with hot mineral acids, wet ashing, combustion in closed containers, high-temperature ashing, or fusion with reagents.
 Solutions containing organic solvents, such as low-molecular-mass alcohols, esters, or ketones, enhance absorbances by increasing nebulizer...

Area of Science:

  • Analytical Chemistry
  • Environmental Science

Background:

  • Accurate quantification of trace elements in tobacco is crucial for understanding its composition and potential health impacts.
  • Traditional digestion methods can be time-consuming and introduce errors.

Purpose of the Study:

  • To develop and validate a simplified, accurate method for simultaneous multielement determination in tobacco.
  • To investigate the relationship between trace element content and tobacco origin.

Main Methods:

  • Tobacco samples were digested using a mixture of nitric acid (HNO3) and hydrogen peroxide (H2O2).
  • Digestion solutions were analyzed directly using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) with Germanium (Ge) and Rhodium (Rh) as internal standards.
  • A final acidity of approximately 2% was maintained for both sample and standard solutions.

Main Results:

  • The method allowed for the simultaneous determination of 30 trace elements.
  • Detection limits ranged from 0.006 to 1.133 ng/mL, with relative standard deviations between 0.90% and 5.66%.
  • Recovery rates for Copper (Cu) and Yttrium (Y) were between 93% and 102%.

Conclusions:

  • The proposed ICP-MS method is suitable for multielement analysis of tobacco.
  • Significant correlations were observed between trace element concentrations and tobacco's geographical origin and classification.
