What is MP AES used for?
MPAES is used for simultaneous multi-analyte determination of elements. The technique provides better linear dynamic range, detection limits, and analysis speed as compared to conventional flame atomic absorption spectrometers.
What is the main disadvantage of Emission Spectroscopy?
Inductively coupled plasma Disadvantages are spectral interferences (many emission lines), cost and operating expense and the fact that samples typically must be in a liquid solution. Inductively Coupled Plasma (ICP) source of the emission consists of an induction coil and plasma.
How many elements can AES detect?
The ICP-AES is an analytical technique based on the principles of atomic spectroscopy for the determination of more than 70 elements with detection limits in the parts per billion to parts per million range. In theory, the technique allows us to analyze all elements except argon.
Why is ICP better than AAS?
ICP is the method of choice when you want to measure multiple elements. In a nutshell: AAS is cheaper but can only determine the concentration of a particular element. ICP-MS is more expensive but faster, more sensitive and can analyze multiple elements simultaneously (can detect down to PPT levels!).
What is the difference between AES and AAS?
While AAS quantifies the absorption of electromagnetic radiation by well-separated neutral atoms, AES measures emission of radiation from atoms in excited states.
What do you need to know about MP-AES?
Since MP-AES is essentially a solution technique, all solid samples have to be dissolved and made solutions before analysis though liquid samples like water can be aspirated directly after making necessary dilution if necessary.
Is the Agilent 4210 MP-AES available without pretreatment?
With detection limits down to ppb levels and no sample pretreatment necessary, the 4210 MP-AES delivers MP-AES analysis at a fraction of the cost of traditional techniques. Runs unattended, without flammable or expensive gas supply, dramatically reducing your operating cost
What kind of plasma does the MP-AES use?
The MP-AES Instrument utilizes a microwave plasma and as it runs on air instead of combustible gases, it can be installed in either a centralized laboratory or a remote location.
Why are Ion lines used in MP-AES?
According to Berg, controlling the ionization of the matrix is desirable since the MP-AES gives a higher reproducibility when determinations are carried out using atom lines compared to ion lines because of its relatively cold plasma.
