For decades, ultraviolet visible spectroscopy was the standard for concentration measurement. Traditional uv vis spectrophotometers use a fixed pathlength approach to generate a single absolute absorbance value. But what if you could get more absorbance values, more data points, and ultimately better accuracy? What if you didn’t have to worry about sample dilution, contamination, and other errors?
The solution is here — the Slope Spectroscopy® method can change the way you measure concentration.
In-line GMP testing — Designed to meet the rigors of regulatory GMP requirements, the new CTech™ FlowVPX spectrophotometer system offers reliable real-time results with integrated ease for concentration measurements during every stage of the downstream GMP process.
Leveraging the power and flexibility of variable pathlength technology, Slope Spectroscopy is a rapid and robust concentration measurement method. Unlike traditional uv vis spectrophotometers, variable pathlength technology allows for our uv vis systems to take multiple reading in real-time. Giving you more absorbance reading, more data points, for better accuracy and more reliable results.
Traditional photometric analysis relies on a single data point at a fixed pathlength. Constraining the pathlength forces the analyst to adjust the sample to ensure it is within the measurement capabilities of the uv vis spectrophotometer. Dilution steps can introduce error due to the variability of techniques and the skill of the analyst. By varying the pathlength with a precision linear stage, Slope Spectroscopy eliminates the need to manipulate the sample and decreases errors. Variable pathlength technology provides an easy alternative to traditional uv vis spectroscopy.
