Many industries use atomic spectroscopy to quantify elements, precisely, but not exclusively metals, in wastewater streams, pharmaceuticals, foods, and consumer products, among others. The two principles created of atomic spectroscopy depend on absorptions and emission.
Based on the absorption of observation radiation by gas-state atoms, Atomic absorption spectroscopy evaluates analyte concentrations to parts per billion. When it comes to fame, atomic absorptions are considered the most popular type, with cold vapor AA and graphite furnace AA following.
When it comes to optical emission (OE) spectroscopy, it comes in two forms that include the most common inductively coupled plasma and flame OE. As the name implies, the love OE operates with flame in exciting the atoms, while ICP employs a high-temperature plasma leading to more structured excitation. ICP OE is significantly used compared to the way flame OE is.
Flame OE is affordable and easier to use. ICP-OE spectroscopy benefits speed, lesser interferences, lower detection limits, and the ability to work on various elements and analyze them successfully within a similar sample. Read on and learn how to choose the right atomic spectroscopy instrument.
Consider the Lab Requirements
The options for element analysis in the Agilent atomic absorption spectroscopy will help if you consider the lab requirements. This is because the techniques tend to complement each other correctly. It might not be clear which of the best solutions for a specific answer.
Buying decisions depend on a lab’s need for detection limits. It is also based on the analytical operating range and specimen throughput. It is significant for every laboratory to be concerned about data quality. This is specifically for workflows that will either support legal proceedings or be regulated.
Additionally, bearable interferences will be depending on the type of sample and industry. Lab operators, managers, and operators are concerned about the availability of standard techniques, costs, and ease of use when it comes to the operational side.
Consider the Instruments as Series
It will help consider flame AA, Graphite furnace AA, ICP-OES, and ICP-MS as a series since an individual can build a decision matrix based on the number of analytes, detection numbers, and volume limits samples.
Consider the Costs
Detection limits, capabilities, and range will be improving as one goes down the list. It is important to remember that added advantages come at a higher price. You can buy a flame AA system from $13,000 to $25000. Nut the price tag will rise rapidly for other instruments.
Consider the Utility and Ideal Application
Some professions also recommend using analyte con concentration levels as the primary cutoff criterion. The concentration ability of the OES and AA techniques range from percentage rates of parts per billion. However, ICPMS goes down to parts per quadrillion. The is the significance of applicability to the market classifications.
Enhanced sensitivity of Agilent atomic absorption spectroscopy comes at a cost. Long are the days when ICPMS was restricted to samples composed of approximately 0.2 percent or minimal dissolved solids. These guidelines will allow you to settle on suitable atomic spectroscopy.
