Application: Gold Particle Testing
SoloVPE systems can be used for Gold particle testing, a highly effective method to validate filters and process integrity in biopharmaceutical manufacturing
Gold Particle Testing
Validation and process integrity testing for Planova filters
Virus-removal filters are a key component in many biopharmaceutical manufacturing processes.
- The gold particle test is the most common and effective way to confirm that the filter pore size has remained unchanged throughout the process.
- Spectroscopic analysis of concentrated gold particle solutions pre- and post-filtration is the preferred method to validate chromatography filter and process integrity.
The SoloVPE Solution
- Undiluted samples are measured using the SoloVPE System to generate section data. Linear regression analysis of the section data will yield a slope value which can be used for quantitation.
- The variable pathlength technology of the SoloVPE System dynamically adjusts the measurement pathlengths to suit the sample being measured and ensures that optimal readings are made.
- The use of multiple data points provides verification that the readings are compliant with the Beer-Lambert law.
- The context of the slope measurement inherently provides a greater level of confidence than a single absorbance data point.
The variable pathlength technology of the SoloVPE System dynamically adjusts the measurement pathlengths to suit the sample being measured, this ensures that optimal readings are made.
