Did you know that there are lots of ways for scientists to figure out what chemicals are inside different materials? They have a special tool called a "UV Visible Spectroscopy Machine" that they utilize! This machine is really cool because it utilizes light to visualize the molecules in a sample.
Here’s how it works: the machine shines a beam of light onto the sample. Next, it gauges how that light interacts with the chemicals there. Different types of chemicals will absorb, or take in, different amounts of light. By using light channelled through samples they can find out what chemicals are present.
When it comes to choosing a machine, there are a few key things to keep in mind. Start, for example, with the range of wavelengths the machine is able to measure. Those wavelengths are different lengths of light waves, and some machines can measure only specific ones. In order to have the best readings,4 you must choose the right machine that can come with a spectrum readability range.
Then, think about how sensitive the machine is. Sensitivity is how effectively the machine can pick up small doses of chemicals. There are machines that can find HUGE amounts, while others can only find tiny amounts. You will need to pick a machine based on the needs you have according to your experiments.
For example, UV Visible Spectroscopy is used by scientists to explore novel materials they create. It can also be used to test how pure a substance is, which means confirming that there are no unwanted chemicals mixed in with it, as well as to explore how chemicals behave under empty conditions, like heat ot pH.
Then, ensure the sensitivity is appropriate for your experiments while the machine is running. You want to ensure it can pick up the right chemical concentrations for your particular research. You could also think about the software’s ease of use. Is it easy to maneuver to find the information you are looking for?
In pharmaceutical companies, UV Visible Spectroscopy is employed to evaluate the purity of drugs. This means the institute helps ensure that drugs aren’t tainted with harmful or unwanted substances. It also identifies concentrations of active ingredients, which are the components of the medicine that actually treat patients. It could also be used by scientists researching how stable drugs are over time, which is important to understand so we can know if it will work.
