Hi there,

Cl is not a cation and therefore one cannot analyse it using ICP-OES or ICP-MS. By far the best method is ion chromatography which can measure anions as well as cations. This method is fast and is able to measure multiple anions or cations at the same time depending on their elution rate from the column. Different columns are used for anions and cations analyses. I hope this helps.

We have the same instrument in our research group and we were told that it is not possible to analyse chloride with it. We have imagined that a possible solution would be the precise quantification of silver by ICP-OES, after precipitating the chloride in solution with silver nitrate as silver chloride. This is however a general thought because it really depends on the matrix to be analysed.

Best of luck!

Thank you for your kind comments.

Dear Z. Aly,

In the literature, the Chloride was analyzed by ICP-OES and ICP-MS  (e.g., "The Chloride analysis of botanical samples by ICP-OES; http://pubs.rsc.org, doi:10.1039/C0JA00059K). I have recently received an ion chromatography instrument and am still working on the method development and validation.

Dear Francesco,

Yes, it is true because it is in red color meaning that one can not select it. It looks good idea to do what you had done, but as you know in this case you are precipitating the chloride, bromide and cyanide as well, Becarefull. Finally, it depends on the sample matrix as you mentioned earlier.

Thank you :) 

We can analyse Chlorine using ICPOES in the range 100ppm and above , wavelengths to be used for the analysis are 858.597nm & 894.800 nm. ICPMS we can analyse using mass 34.969 calibration ranging from 0.1ppm.

I am sending 2 paper for determination of Cl by ICP-OES. The prominent line of Cl is 134.72 nm. The ICP-OES equipment  has to give possibilities for determination of elements in this spectral region.

Nonka is right. That means that you need an instrument equipped with a monochromator which can handle "deep" UV region of spectrum.

P.S. As far as I know, some ICP-OES instruments from the "SPECTRO" company (e.g. SPECTRO Arcos) can handle this (Cl 134.7 nm) wavelength. 

Dear Jerzy, Yes.The SPECTRO ARCOS can be outfitted with an interface for either axial or radial plasma observation. The CCD optic system with a Paschen-Runge mount assembly delivers a matchless resolution of 8.5 picometer in the

wavelength range from 130 to 340 nm. 

Thank you for your valuable comments

Is it possible to determine the Cl, Br, I amount using ICP-AES ?

Dear colleague,

The problem becomes especially acute in the UV/VUV range between 130 nm and 190 nm. With its optimized holographic mastergratings housed in a single cast-aluminum hollow-section optical chamber featurin32 line array detectors, SPECTRO ARCOS (SPECTRO Analytical Instruments GmbH, Germany) has a wavelength range from 130 nm to 770 nm. An optimized ARCOS optic provides access to additional wavelengths for the halogens — chlorine at 133/134 nm emission wavelength, bromine at 154 nm, and iodine at 161 nm. Users report this capability is especially useful in analyzing petrochemicals, pharmaceuticals, fertilizers,and high-purity chemicals.

With kind regards, N. Daskalova

Hello Debashrita,

Generally anions cannot be identified by ICP-OES/ICPAES technique. If you aspirate the solution having chloride, bromide etc. in it, the argon gas which you are using as plasma in ICP-AES/OES will bind with Cl-/Br- etc and hence proper emission from element of interest will not occur. So you get error results in evaluating concentration of anions; and the remaining problems are discussed above only. ICP-OES is the best technique to analyse base metals with quantification.

Hi Debashrita

You should be used ion chromatography for the determination of anions (Cl,...)

Best regards

Pourya

Very very good.
