UV Vis Spectroscopy is a simple and commonly used technique based on the absorption of light in a given sample. Depending on the amount of light and wavelength absorbed by the sample, valuable information can be obtained, such as the concentration or purity of a sample, for example in the caffeine spectrum below. In addition, because each substance absorbs light in a different way, a unique and specific relationship exists between the substance and its UV Vis spectrum. Spectrophotometry can then be used to identify a substance.
A UV Vis Spectrophotometer measures the intensity of light passing through a sample solution in a cuvette and compares it to the intensity of light before it passes through the sample. The main components of a UV Vis spectrophotometer are a light source, sample holder, dispersive device to separate the different wavelengths of the light, and a suitable detector, for example a photo diode detector.
There are five main reasons UV Vis spectra are measured:
Our spectrophotometry portfolio has been designed to fit in several industry segments:
A micro-volume spectrophotometer performs measurements using small volumes of sample (as low as 1 microliter). Highly concentrated samples can also be measured without further dilution due to LockPath technology on the METTLER TOLEDO UV5Nano, which can set the path length at either 0.1 or 1 mm.
METTLER TOLEDO offer a solution to performance verification in the form of the CertiRef™ unit, which is the most efficient way to check whether your spectrophotometer is working according to pharmacopeia regulation. This accessory automatically performs tests for wavelength accuracy and repeatability, photometric accuracy and repeatability, resolution, stray light, photometric noise and drift, as well as baseline flatness.
METTLER TOLEDO LabX software enables users to have higher flexibility by creating custom workflows exactly for the user's needs. Calculation and transcription errors are completely avoided. It also ensures data integrity with all information safely stored in a secure database, including all performance verifications and services. With security features such as electronic signatures and user management, it assists to comply with 21 CFR part 11 regulations from the FDA.
