Molecular analysis helps in identifying the composition at the genus level. The technique also determines the shifts of a community due to environmental changes. Throughout the decades, manufacturers introduced new spectroscopy techniques and equipment. The spectroscopic techniques usually involve absorption, reflection, and emission for molecular analysis. 

However, aside from the techniques and methods, choosing the right equipment can reveal much information about a specific molecule. Molecular spectroscopy instruments’ criteria and factors should come first before considering the budget. 

Factors To Consider In Selecting Appropriate Spectroscopic Equipment for Molecular Analysis

Your equipment of choice should meet fundamental requirements. This is because the right equipment will be sustainable for future and unforeseen needs and avoid overspending. So, we listed some factors to consider when selecting Spectroscopic Equipment for Molecular Analysis. 

Characteristics of Target Samples

The size, shape, and density of samples should be considered. The spectrometer should accommodate the minimum and maximum size of samples to be examined.

Machine Size

The size of the machine should be able to hold the samples. There are also different sizes together with different features of the spectrometer. The operational environment should also be considered when buying, like laboratory refrigerators.

You want to know how you will use and store the equipment. Near-infrared spectrometers, Visible light spectrometers, and UV-VIS spectrometers are just some types you can choose from.

Spectral Range

The Spectral Range or Wavelength Range should match the product or material’s spectroscopic characteristics. The range capacity will help identify and detect the chemical composition or elements in the sample. The element’s emission can be revealed and then detected to identify its wavelength range. Other spectrometers provide frequencies by optical signals through a light source.

One way to determine the wavelength range is to test the absorption of the material. A spectrometer should have a visible spectrum of 190 nm to 1100 nm, depending on your goals, to identify most colored materials.

Method Options

The spectrometer had two testing method options; preconfigured and customizable. Both are capable and depend on your application and operational environment. The testing method is needed to be considered, especially now that there is a continuous demand for molecular spectroscopy equipment.

Detection Lines

Each spectrometer will have different detection limits. The detection limits must meet your needs and goals for analytical problems. A practical spectrometer should be able to handle different research elements.

Measurement Time

A fast measurement time is helpful, depending on your operational environment. High-speed spectrometers can provide powerful communication protocols, production efficiency, data acquisition, and a smooth onboarding process. Some industries like medicine, security, food, and agriculture can gain from this spectrometer. 

However, some industries, like education, don’t necessarily need faster data acquisition. Other examples could be material analysis for the manufacturing industry.

Other criteria that you should consider in selecting spectroscopic equipment:

• The field of view required
• Features and Functionality
• Your expertise and experience with the equipment
• Data analysis software
• Maintenance of equipment
• Reliability
• Seller’s customer service and warranties

Know what you need for a Spectroscopic Equipment

Picking the best spectroscopic equipment should not only be based on its cost. Knowing the criteria will help get quality equipment for molecular analysis and future laboratory research. It’s also important to note purchasing factors, the researcher’s expertise, research goals, and the operational environment.
