Hi Mohammad,

Obviously, this is a very broad question, and the answer strongly depends on the type of projects that you have in mind. From the perspective of analytical chemistry, I would go for an advanced LC-MS system. With such a device, a large variety of (non-volatile) organic compounds can be detected, even if they are present in (very) low concentrations.

If you are working on the quantification of metals, an ICP-MS can also be interesting but then you will only be able to analyze predominantly metallic species.

Hopefully it helps,

Niels

This question is a broad one. It would have been nice if you can specify what area or field the instrument is to be used. Anyways i can suggest Atomic Absorption Spectrophotometer (AAS) as ut can be used to quantify a variety of metals

Hey Niels

Thank you so much for sharing

May I ask why you think HPLC-MS is superior among the other HPLCs with other detection systems ? Is it technically easy to operate and maintain ?

Thanks alot for sharing

Do you think that AAS is better than ICP-MS or the other instruments used for metal ions determination in terms of sensitivity, atomization and expense ?

It depends on your project but in my opinion, for structural, optical and morphological characterization of materials, following instruments are useful.

1. X-ray Diffractometer

2.UV-Vis Spectrophotometer

3. Scanning and Transmission Electron microscope.

Wow thats interesting how can you use UV-vis in characterization when just measuring absorbance that is related to concentration and quantitative purposes
