Purchasing Guide: Spectroscopy
When purchasing, consider what detection range you will require for your sample type and look for instruments that are sensitive, accurate, and consistent
Spectrophotometers/spectrometers can be used to determine the chemical makeup of a solution or a concentration of a known substance in a solution, such as DNA. These instruments measure the intensity of visible, UV, or infrared light that passes through a solution. When purchasing, consider what detection range you will require for your sample type and look for instruments that are sensitive, accurate, and consistent.

7 Questions to Ask When Buying a Spectrophotometer:
- What types of samples will you be measuring and what range of wavelengths will you require for those samples?
- What are the detection limits of the instrument?
- Do you need an instrument that can analyze multiple samples at a time?
- How long does it take to measure each sample?
- Do you need a double-beam instrument to increase your efficiency?
- Will your samples be in cuvettes or microplates?
- Is your sample quantity limited? If so, a microvolume spectrophotometer may suit your needs best.
The Importance of Water Purity
For the best results, make sure that the water your sample is suspended in is highly pure. If there are contaminants in the water, the scan results will be inaccurate and could negatively impact your research.
