I have liquid sample having heavy metal contents . Is FTIR is usefull to detect it on primary level?
Well Its fine but I prefered to advice you that analyse your samples with the help of Atomic Absorption Spectophotometer.
Dera Dnyaneshwar R. Shinde,
These equipment are not suitable (very rarely you can use this equipment by indirect method for some metals only) , this is a fundamental.
You have to use one of following equipment
You have to select an one of above according to levels of metals in your samples.

Hello Shinde,
FTIR technique can use to determine the effect of heavy metals with some compounds or materials. But to determine the concentration of metals in liquid samples, you can use AAS- Flame or GF, ICP-MS, ICP-OES and XRF. These methods can measure the concentrations in ppm, ppb and ppt levels.

Dear Yohan,
XRF is not a successful method to determine metals in aqueous or liquid samples.

Dear Piyal Aravinna,
Most of researchers prefer to use AAS and ICP techniques for determination of heavy metals in liquid samples after digestion. XRF usually use to determine elements in solid samples but also some liquid samples. Many preconcentration methods for the analysis of liquid samples by X-ray spectrometric techniques have been developed in the last decades therefore, we can not say the XRF not successful because there are some studies were done using XRF for liquid samples. All of these techniques have a number of advantages and disadvantages and giving the analyst the flexibility to choose which technology suits best.
