UV-Vis Spectrophotometer Survey 2016 Results

Find out our readers’ top ten uses and more from our latest UV-Vis spectrophotometer survey results.

By

Ultraviolet-visible (UV-Vis) spectrophotometry is arguably the most common as well as one of the oldest forms of absorption-based analysis. UV and visible regions of the electromagnetic spectrum are contiguous: UV wavelengths range from 10 to 4000 angstroms; visible wavelengths range from 4000 to 7000 angstroms


Top 5 Questions You Should Ask When Buying a UV-VIS Spectrophotometer

  1. For what applications will you be using the instrument for? This will help you determine the detection range you require. Don’t forget to consider future applications that may require a broader range
  2. What range of stray light performance are you comfortable with for your application and budget?
  3. Consider what sort of samples you’ll be working with in order to determine what absorbance range you will need in your UV-Vis spectrophotometer. For example, if it is a turbid or concentrated liquid or a solid sample that is optically thick, you may require a working absorbance range between 5 Å and 8 Å or higher.
  4. What level of throughput and reliability do you need?
  5. How much will the instrument cost? Don’t forget to factor in the cost of maintenance, etc. along with the cost of acquisition.
