What instruments are used for qualitative and quantitative analysis of organic-inorganic mixtures?

For qualitative and quantitative analysis of organic and inorganic mixtures, various instruments and techniques can be used. Here are some suggestions:

1. Liquid Chromatography-Mass Spectrometry (LC-MS):

For the analysis of organic compounds, LC-MS can achieve efficient separation and high sensitivity detection. It allows qualitative and quantitative analysis of organic components.

2. Inductively Coupled Plasma Mass Spectrometry (ICP-MS):

For inorganic substances, especially metal elements and isotopes, ICP-MS offers high sensitivity and a wide linear range. It enables simultaneous qualitative and quantitative multi-element analysis.

3. Gas Chromatography-Mass Spectrometry (GC-MS):

If the organic compounds have low boiling points and are volatile, GC-MS can be used for qualitative and quantitative analysis.

4. Atomic Absorption Spectroscopy (AAS):

AAS can be used to analyze metal elements in inorganic substances. It allows for simultaneous qualitative and quantitative multi-element analysis, although its sensitivity is lower compared to ICP-MS.

5. Ultraviolet-Visible Spectroscopy (UV-Vis):

This method can be used for qualitative and quantitative analysis of substances with specific UV or visible absorption characteristics, both organic and inorganic.

6. Quadrupole Inductively Coupled Plasma Mass Spectrometry (ICP-QMS):

For inorganic analysis, especially of metal elements, ICP-QMS offers high sensitivity and a wide linear range. It enables simultaneous qualitative and quantitative multi-element analysis.

7. Fourier Transform Infrared Spectroscopy (FTIR):

For organic compound qualitative analysis, FTIR provides structural information. However, it is usually not suitable for quantitative analysis.

8. Nuclear Magnetic Resonance (NMR):

For qualitative analysis of organic compounds, NMR provides detailed structural information. Quantitative NMR (qNMR) can also be used for quantitative analysis under specific conditions and calibration.

9. X-ray Fluorescence Spectroscopy (XRF):

For inorganic analysis, especially of metal and non-metal elements, XRF is a non-destructive method for qualitative and quantitative analysis.

Depending on the nature of the sample and the analysis requirements, one or more instruments and techniques can be selected for the qualitative and quantitative analysis of organic and inorganic mixtures.
