Among the many scientific instruments, a lab may possess, are those that are capable of identifying specific substances and/or their characteristics or concentrations. Several devices are capable of accomplishing this; however, the most common way is to use a spectrophotometer. With several types and configurations available, it is possible to find the right spectrophotometers for each application.
Applications
You can find these specific types of photometers in chemical labs across the globe. In particular, they find employment in the following fields:
Spectrophotometers are designed with the capability to measure many different substances and materials. Main applications are to
Overall, these instruments can measure anything from solid metals to liquids. To meet the various demands and applications, they are available in different types and configurations.
Types – Configuration
While these instruments are available in different sizes, shapes, and configurations, they are of only two basic types:
While double-beam spectrophotometers make comparison measurement more facile, single-beams offer a more compact design and are more highly sensitive to fluctuations in the source of light.
Other Types of Spectrophotometers
Another way of categorizing these instruments is according to what type of light they measure. Accordingly, spectrophotometers may measure the following:
Your selection of spectrophotometer relies on such factors as application, preferred functionality, and portability.
