Normally macro nutrients like a calcium , sodium determined by easily method but micro nutrients like zink, coblat and iron not determined .
Your question is quite general and difficult to answer at the moment. Could you elaborate upon what you mean by "any" sample.
Do you mean:
- water (fresh, salt, hypersaline)
- soil (surface, subsoil, cropping, urban, polluted)
- rock (any number of origins, depths, etc)
- plant (root shoot seeds fruit etc)
- animal (which tissues or organs, wild or domestic, farmed)
- fungal, microbial or other single-celled organism?\
- metals (pure or alloyed)
- Manufactured samples.
I could go on...
How much sample to you have to spare (milligrams or kilograms)?
Did you want to keep the sample intact or use it up in the preparation process?
By elaborating your question someone might be able to offer a more useful answer than this one.
[PS You need not use quite so many question marks, it is in the questions section already.]
Thanks matthew sir , sample will be liquid which contain macro and micro nutrients .
for example milk, milk contains macro and micro nutrients. macro nutrients easily determined but micro nutrients does not determined from samples. if any method to determined micro like zinc, iron, cobalt .
Suppose you have no proper facility like a chromatography ( adsorption, gas , hplc ) in your lab. whenever sample came to test in your lab or to estimation macro or micro nutrient which is based on only chromatography.
Can I suggest you Google "inductively coupled plasma", or "atomic absorption spectroscopy"?
You might also want to investigate titration methods for cations if you don't have access to advanced equipment.
You might want to speak to your colleagues at your University who wrote this article:Article STUDY OF HEAVY METALS CONCENTRATION IN GROUND WATER SAMPLES ...
Except iron , none of these nutrients can be determined , unless AAs or ICP is used....In good olden days , we used to determine iron colorimetrically using orthophenenthroline ...
According to Ken Neubauer and Nick Spivey (2016), ICP-OES is an ideal technique for measurement of elemental nutrients in soil and food: https://www.spectroscopyonline.com/view/micronutrient-analysis-soil-food-determination-icp-oes

Another very rich document in relation with the subject indicating among other things that Copper, iron, manganese and zinc were extracted from all soils by two extraction methods, AAAc-EDTA and DTPA as extractants.
