Applications: UV ZETA Analyzer

The OMA-300 UV ZETA Analyzer produces results in real time by measuring the light absorbance of a liquid or gas sample by utilizing the Beer-Lambert law to correlate the light data to the chemical concentration of an analyte. The OMA-300 UV ZETA uses a UV detector and simultaneously scans a 190-435 nm wavelength range.

Technology: UV ZETA Analyzer

Principle of Operation

The OMA determines the chemical composition of a sample by monitoring changes in the sample’s UV absorption spectrum with Applied Analytics’ specially designed Zeta™ UV Spectrophotometer. The system measures absorbance at 190-435 nm and quantifies the amount of light absorbed by the sample; the OMA plots this raw data to visualize a high-resolution absorbance spectrum.

In a spectrophotometer, higher light transmittance provides more robust data. This was the guiding principle for designing the Zeta™ UV Spectrophotometer., which maximizes light throughput while eliminating traditional sources of noise (e.g. focusing mirrors).
