Atomic spectroscopy is widely used in qualitative and quantitative determination of about 72 chemical elements in the periodic table.

Spectroscopic methods of analysis are based on the measurement of electromagnetic radiation absorbed or emitted by the analytes (Atomic Absorption Spectrometry Emission Spectroscopy Inductively Coupled Plasma).

It is noteworthy that in both methods are important that the sample is digested by acidic media in order to be introduced to the equipment of atomic absorption or plasma emission, which is why the samples do not have this feature, you must first be previously treated. A truly efficient alternative to solve this is to microwave digestion.


In CIMAV Campus Monterrey,  we have  the infrastructure for the treatment and elemental chemical analysis of different samples such as: soil, water, minerals, ceramics, metals, polymers, food and biological samples.

The equipments that currently provide these services are:

  • Microwave digestion of samples  CEM-MARS 5

  • Atomic Absorption Spectrophotometer  Thermo Electron-M6

  • Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) -iCAP 6500 Thermo Electron
