Nova's analyzers leverage optical spectrophotometry, a quantitative analysis technique using light to directly measure component concentrations in a plating solution. The highly accurate and fast method combines spectrometry, the measurement of the spectrum, and photometry, the measurement of light absorption at one or several wavelengths. Requiring little maintenance, optical spectrophotometry covers multiple parts of the electromagnetic spectrum, such as UV (ultraviolet) wavelengths of 200nm-400nm and VIS (visible light) wavelengths of 400nm-800nm respectively. High Accuracy Directly measures light-absorbing components with high accuracy Non-Destructive Executes non-destructive, non-reagent (NRA) measurements Robust and Fast Advanced electronics and computer algorithms enhance speed and accuracy Flexible Chemistry optimized wavelength and path length Flexible and Extendable Covers a wide range of concentrations from ppb to g/L Low Maintenance Requires little maintenance With optical spectrophotometry, it is also possible to modify or extend the measurement of components that do not absorb light. This is done through a derivatization technique, where a chemical reaction is created to transform the components into a measurable state, prior to the analysis.
