What are the advantages of ICP over AAS?
The advantages of the ICP-MS technique above AAS (Atomic Absorption Spectroscopy) or ICP-OES (inductively coupled plasma optical emission spectrometry) are: Extremely low detection limits. A large linear range. Possibilities to detect isotope composition of elements.
What is the difference between atomic absorption and ICP?
The main difference between AAS and ICP is that AAS measures sequentially while ICP measures simultaneously. For each element you analyze in an AAS, the instrument runs the test separately and each hollow cathode lamp emits its light and the absorption is measured for a single element in each run.
Why is ICP rarely used for atomic absorption spectrometry?
Serious disadvantages of an ICP as an atomic reservoir for AAS are the reduced sensitivity and lower detection power compared to flame—AAS.
What is the advantage of ICP-AES over the flame AES?
ICP OE is more widely used than flame OE is. ICP-OE spectroscopy has the advantage in speed, lower detection limits, fewer interferences, and the ability to analyze multiple elements within the same sample. Flame OE is less expensive and easier to operate.
Why do we use ICP?
ICP (Inductively Coupled Plasma) Spectroscopy is an analytical technique used to measure and identify elements within a sample matrix based on the ionization of the elements withing the sample.
What are the advantages of atomic absorption spectroscopy?
The main advantages of AAS are that it is relatively inexpensive and easy to use, while still offering high throughput, quantitative analysis of the metal content of solids or liquids. This makes it suitable for use in a wide range of applications.
Why mass spectrometry detection is an advantage for ICP spectroscopy?
Advantages to ICP-MS include the favorable detection limits (0.01 to 0.1 micrograms/L for many elements), simple specimen preparation, high throughput (about 40 specimens per hour), and the ability to measure more than one element simultaneously. A major disadvantage is the high capital cost of the instrumentation.
Why argon gas is used in ICP-MS?
Argon gas dilution significantly improves plasma robustness allowing the direct analysis of high matrix samples such as undiluted seawater using the iCAP Q ICP-MS. Optimum performance for high IP analytes in such samples is only possible however, after online addition of water vapor and carbon.
What can ICP detect?
Inductively coupled plasma mass spectrometry (ICP-MS) is an elemental analysis technology capable of detecting most of the periodic table of elements at milligram to nanogram levels per liter.
What is the main reason why ICP has lower limits of detection than other high temperature techniques?
The very low detection limits are due to the very high degree of atomization in the argon plasma at approximately 7000 K (Dean, 2004). This extreme temperature makes it far superior to the graphite furnace as an atomization source for atomic absorption spectrometry.
Why chemical interferences are less common in ICP-AES than they are in flame AAS?
Ionization interferences are less severe in ICP than in flame emission since the buffering effects of electrons from argon ionization diminish analyte ionization in ICPs.
What are the applications of ICP-AES?
Applications. Examples of the application of ICP-AES include the determination of metals in wine, arsenic in food, and trace elements bound to proteins. ICP-OES is widely used in minerals processing to provide the data on grades of various streams, for the construction of mass balances.
Which is better AAS or ICP-OES?
ICP-MS is more accurate, favourable, less time-consuming, and not cost-effective for measuring multiple atoms. In comparison, AAS is less accurate, less favourable, more time-consuming and more cost-effective. In comparison to ICP, AAS is cheaper but can only determine the concentration of a single element.
What is the difference between ICP AES and ICP-OES analysis?
ICP OES vs ICP AES – What's the Difference? Nothing. Inductively coupled plasma optical emission spectroscopy (ICP-OES) and Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) are the same thing.
What is difference between ICP-OES and ICP-MS?
ICP-OES quantitation is based on measurement of excited atoms and ions at the wavelength characteristics for the specific elements being measured. ICP-MS, however, measures an atom's mass by mass spectrometry (MS).
What is ICP AAS?
Inductively coupled plasma atomic emission spectroscopy (ICP-AES) is a method of emission spectroscopy that excites atoms and ions with a plasma, causing it to emit electromagnetic radiation at wavelengths characteristic of a particular element.

IC, ICP and AAS: Advantages and Disadvantages - Chromatography Forum
Ion Chromatography Advantages: Can also do non-metals (F-, Cl-, SO4--, etc) Disadvantages: Generates lots of chemical waste, long run times, can be interferences from sample matrix
Which is faster, flame or ICP?
If we are measuring only one element, the flame AAS is much quicker than ICP in equilibration time; with 3 secs in average for flame AAS compared to ICP time of 25 secs in average. Graphite furnace AAS are generally slower and require more time to equilibrate.
Which element is more sensitive, ICP or flame?
Observing the above table, we can deduce that generally, the ICP has a higher sensitivity than the flame AAS. It depends on the method and application. However, certain elements like phosphorous. sulfur, thalium, and carbon for example; are only detectable by ICP. On the other hand, the flame AAS fares better for cerium.
Can ICPs be measured with flame AAS?
Again, it should be noted that ICPs become feasible when the analyst wishes to measure more than 10 elements per sample; especially in test-for-fee labs that value the productivity of the laboratory. For analysts searching for one or few elements; flame AAS becomes the most viable option in terms of cost. One could invest in a GF AAS if certain elements are not possible to properly analyze by flame AAS due to the insufficient energy of flame atomization compared to furnace atomization.
Is Flame AAS expensive?
Flame AAS are not expensive compared to GF AAS or ICPs. In the order of cost; the following sequence is the typical:
When was inductive coupled plasma invented?
In the 1970s , the new technique of Inductive Coupled Plasma was developed. It involves a generation of a high density electromagnetic field into a coil from an RF generator. The current generated from the electromagnetic field induces high temperature thermal plasma estimated at 10,000K; where a plasma torch is generated from a quartz tube inside a cooled chamber that is engulfed within the coil.
Is AAS or ICP more complementary?
In conclusion, it can be said that AAS and ICP are rather complementary techniques than competing ones; and this greatly depends on the analytical task at hand. For certain applications or productivity requirements, AAS becomes more feasible; in other cases, the ICP becomes more the technique of choice for the task. In other cases, cost is the deciding factor in favor of one technique against the other, ICPs could cost as high as six times the cost of a flame AAS; and with the limited budgets in laboratories in some cases, the ICP becomes an infeasible choice even though the analytical task greatly justifies it.

Which is better, ICP or AAS?
The ICP-MS is 1000 times better then AAS as the sensitivity is 1000 times more. It also has more throughput then AAS and can perform multiple element in a single run. The application of AAS is limited to few elements but ICP-MS can analyze maximum elements in the periodic table.
What is the difference between AAS and ICP?
The ICP uses an MS (mass spectrometric detector) while AAS uses a UV-Visible spectrophotometer as a detector. The ICP (plasma) has a higher flame temperature so ALL the atoms are in emission while the AAS has a much cooler flame and thus atoms can either emit or absorb radiation. Cite. 30th Aug, 2019.

Is ICP-MS more sensitive?
Obviously ICP-MS is more sensitive and simultaneous but very expensive. It depend what you want to do. Using ICP-MS for analysis needs proficient operator. Operating AAS and processing it's data is much easier.
Is there a correlation between ICP and AAS?
I agree with Bruce Neagle. There is some correlation between ICP MS data and AAS data.
1. Simple, fast and safe sample preparation
Measurements by XRF are carried out directly on the solid material (or liquid) with little to no sample preparation. XRF analyzes any type of sample without the need for dilution or digestion and therefore no disposal of chemical waste is necessary.
2. Non-destructive technique
In benchtop XRF spectrometers the sample is excited using an X-ray tube and the characteristic X-rays from the sample are detected and automatically processed by the software. These low-power X-ray tubes don’t produce an extensive amount of X-ray photons or heat and therefore don’t damage the sample or alter its crystal structure.
3. Low cost of ownership
Taking into account the initial costs of instrument and infrastructure, and running costs of gasses, acids, electricity and waste disposal, XRF benchtop spectrometers are far more cost-effective than ICP and AAS. XRF does not require the use of expensive acids, gasses and fume hoods.
4. Analysis at the production site (at-line)
Since no gasses, liquids, acids or fume hoods are necessary to operate the XRF benchtop spectrometer, the instrument can be placed in the production facility, right next to the production line for at-line process control.
5. No need for daily re-calibration
The latest advances in excitation and detection technology make the current generation of XRF benchtop spectrometers very stable. In comparison with ICP and AAS, XRF doesn’t need gasses or liquids to operate.
