5 Essential Tools For A Chemical Analysis Laboratory
Chemical analysis surrounds a world of diverse methodologies, detailed concepts, and the pursuit of accurate data. This requires the correct equipment. These tools come in all shapes and sizes and are unique to a lab’s requirements.
In this guide, we delve into five essential tools necessary for a chemical analysis laboratory’s arsenal. When you have the right equipment, you can reveal data hidden within the composition of matter. Read on to learn more.
1. Ultraviolet-visible (UV-Vis) Spectrometer
Molecules boast various detailed secrets. The UV-Vis spectrometer helps a chemical analysis laboratory to analyze how light and matter communicate. How? By measuring the sum of light absorbed at different wavelengths, this nifty piece of equipment ensures you gain insights into the concentration and structure of a molecule. Color, in essence, is a clear path to comprehending the ins and outs of chemical composition.
There are various UV-Vis Applications available:
- Highlighting Unknown Compounds: UV-Vis scans can showcase characteristic absorption patterns. This allows you to compare one compound with another through databases of known compounds. This can lead to the identification of the compound.
- Analytes Quantification: Embracing the Beer-Lambert Law, which surrounds absorbance and concentration, the UV-Vis spectrometer can help you pinpoint the sum of a specific colored compound in a solution.
How to Pick the Correct UV-Vis?
When choosing the correct UV-Vis spectrometers, you’ll be pleased to learn there are various options available. This means there is one bespoke to your lab’s needs. Invest in a single-beam tool if you’re looking to carry out a routine analysis only. If your research is more complicated, choose a double-beam instrument instead.
2. The Analytical Balance
The analytical balance is one of the most sought-after tools when meticulously measuring mass. Contemporary tools are void of clunky beam balances and boast incredible precision. With these nifty tools, you can gain remarkable readability levels of 0.0001 grams (0.1 milligrams). This extreme accuracy allows you to quantify the sample sum using precise methods.
This is particularly beneficial to those who need to carry out analytical techniques such as standard solution preparation and gravimetric analysis:
- Gravimetric Analysis: If, for example, you’re trying to separate alloys from components, the analytical balance measures the sum of each purified element with extreme precision. This helps you to pinpoint the exact metallic element content.
- Standard Solution Preparation: For several analytical techniques, creating a standard solution with a known concentration is crucial. The analytical balance tool enables you to highlight the weight of a pure compound. A predetermined concentration can then be dissolved in a solvent.
Precision in this industry is crucial. In addition, data logging, internal calibration capabilities, and draft shields heighten the integrity of data and user experience. If you’re a chemist who handles hygroscopic (moisture-absorbing) samples, a balance tool that boasts a desiccator compartment is an asset. Why? By lessening moisture absorption, you can calculate accurate mass determination.
3. High-Performance Liquid Chromatography (HPLC)
HPLC is another noteworthy chromatography technique. It works by separating combinations of compounds based on how they interact with both a mobile and stationary phase. To get these results, complex solutions enter columns packed with the stationary phase, while the mobile phase transports components through at rates based on their affinity for the stationary phase. The result? You can pinpoint the individual identification and isolation of components.
This tool comprises the following techniques:
- Environmental Monitoring: In this age, contaminated water is a rising concern. HPLC is crucial to separating and pinpointing pollutants in water samples, thus aiding environmental monitoring and rectifying efforts.
- Drug Analysis: When analyzing complex pharmaceutical formulations containing various excipients and active drugs, HPLC helps to separate the drug from the excipients. This allows you to determine both the potency and purity of the compound.
How to Pick the Correct HPLC System?
There are several HPLC systems on the market that are bespoke to various analytical requirements. For generic separations, an isocratic system can be used. For gradient separations or complex mixtures, a gradient HPLC system ensures you have heightened control over the mobile phase composition. This provides an improved resolution overall.
Other factors to consider when deciding on detectors include the analytes of interest. For example, traditional detection methods comprise UV-Vis, fluorescence detection, and mass spectrometry.
4. The pH Meter
Although measuring pH balances seems simple, it plays a crucial part in chemical analysis. A pH meter tool helps you to reveal the hydrogen ions (H+) concentration in a solution by gauging its acidity or alkalinity. The pH scale is numbered from 0 to 14. 0 is the most acidic, while 14 is the most basic (alkaline).
At one time, researchers only had access to simple pH test strips, which are not renowned for their accuracy. pH meters are much more accurate. There are various pH meters available, designed for the laboratory and fieldwork.
Different Types of pH Meters
There are three primary pH meters available. These include:
- Handheld (wireless) pH meters and pens
- Glass and reference electrodes
- Combination electrodes
- Benchtop pH meters.
5. Glycerin (Glycerol)
Glycerin, or glycerol, has a chemical formula of C3H8O3. It comes from plants and animal fats and is a byproduct of biodiesel produced from triglycerides.
This product is beneficial to laboratories as a solvent. Why? It is miscible in water. Its low freezing temperature can lessen the freezing point of various solutions. This is an asset in processes such as enzymatic analyses.
The Bottom Line
There are various tools and equipment available on the market. Before investing in tools, consider your industry, what you will be using these tools for, and the type of laboratory you work in. This will help you to pick the correct tools, ensuring you get the most out of them. It will also ensure optimal, accurate results.
Chemical analysis heavily relies on unearthing accurate data. These tools will help you to unearth this in a hassle-free, efficient way.
