Elemental Analysis

Elemental analysis is a chemical analysis method for studying the composition of elements in organic compounds. It is divided into qualitative and quantitative. A method of determining the elemental composition and percentage of a compound by a chemical reaction. The former is called elemental qualitative analysis, and the latter is called elemental quantitative analysis. After a complete elemental analysis, the experimental formula of the compound can be calculated. Knowing the molecular weight of the compound, which can also fix the formula, supplemented by other methods known the structural formula.

The task of elemental analysis is to identify which elements, groups of atoms or compounds a substance consists of. According to different analysis conditions, it can be divided into dry analysis and wet analysis. According to the difference of sampling, it can be divided into constant analysis, semi-micro analysis, microanalysis and ultra-micro analysis. For samples with unclear sources, the qualitative analysis should be performed first and then quantitative analysis.

Our Elemental Analysis Testing Techniques are as follows:

  • Inductively coupled plasma optical emission spectrometry (ICP-OES)
  • Inductively coupled plasma mass spectrometry (ICP-MS)
  • X-Ray fluorescence spectroscopy (XRF)
  • Ion selective electrodes
  • Ion chromatography (isocratic and gradient systems)
  • Karl-Fischer water determination
  • Micro analytical combustion methods (C, H, N, O, S, halogens, residue on ignition)
  • Scanning electron microscopy with energy dispersive X-ray analysis (EDX)
  • Total organic carbon (TOC)

Below is a list of our elemental analysis test services (include but not limited to the following):

Identify unknowns

Our team can learn from the experience of different sample technologies to identify the elemental composition.

We provide robust elemental analysis to ensure that traces are within acceptable limits.

Our scientists provide fast and professional solutions for analyzing problems encountered in samples analysis.

Quality control is especially suitable for routine analysis to ensure the high quality of medical products, safe pharmaceuticals and health care industries.

Proper sample preparation is essential to obtain reliable quantitative data. We select the most suitable technique for the sample from a series of sample preparation methods.

When our team analyzes food contact materials or pharmaceutical containers, the samples are used to support food or pharmaceutical packaging compliance to demonstrate that they meet with national and international standards.
