2 Ways of Quantifying Metals

Metals are a huge part of our daily lives. Most of the new technology that we use is made of metals. Many of these have metals as their basic foundations, from phones to computers, cars, and buildings.

Along with everything in the universe, nothing is unlimited, and we should be very aware of the number of metals that we use to plan.

There are many ways to quantify metals, from trace metal analysis to Agilent atomic absorption spectroscopy. These tools would help realize how much metal people use in their lifetimes. Additionally, with the ever-growing technological age, we should plan for metal replacements as they are finite and mostly non-renewable.

Reading this article should give you a good understanding of how to quantify metals.

Main Ways Of Quantifying Metals

Metals are quantified typically in ppm (parts per million), ppb (parts per billion), and ppt (parts per trillion). The units used vary heavily on the analytical technique to be used. Knowing this, there are two main ways of quantifying them using spectroscopy and trace metal analysis.

1. Atomic Absorption Spectroscopy

AAS (Atomic Absorption Spectrophotometry) is a well-known technique for quantifying metals. Their advantages lie in the fact that people can use them in many different samples of metals. There are three models that you can use AAS, Flame AAS, Furnace AAS, and the AA Duo model.

Flame AAS is used the most since it is the cheapest and the easiest to use out of the three. Furnace AAS produces a higher quality result since it has better detection limits than Flame AAS at the cost of money and difficulty. The AA Duo model gives you the best parts of each model and finds the sweet spot between being too cheap and too hard to execute.

2. Trace Metal Analysis

Meanwhile, trace metal analysis exists as a substitute technique for quantifying metals. Trace metal analysis shows great accuracy when talking about small and heavy amounts of metals in any sample. The analysis of trace metals is a very strict procedure, so the samples given must be measured to the most accurate calculation possible.

Trace metal analysis can be a gruesome task that faces many challenges when executed. These include laboratory conditions, sample preparation, and workflow efficiency.

If the samples or the given equipment used are contaminated, it could easily affect the analysis results. Cleanliness is of utmost importance when working with very delicate samples. Additionally, even if your samples and equipment are clean, it would be a great help if you could isolate the surfaces that the sample would touch when being analyzed.


Quantifying metals is never an easy task with all of the requirements. On the positive side, it delivers very accurate information that would be important in our lives today and in the future.

Hopefully, this article provided you with a good insight into how you could understand the different techniques of quantifying metals. It garnered an appreciation for the people who do this tedious work.
