When choosing a QCM-D instrument, there are several aspects to take into consideration. If you have identified automation and reproducibility as critical factors for your needs, both the QSense Omni and QSense Pro excel in these areas. Even though there are similarities, the two products are tailored to different needs and have their respective unique strengths. This guide aims to help you decide which instrument best suits your requirements by providing a detailed comparison of their features and capabilities.
Both QSense Pro and QSense Omni were designed with high throughput, low sample volume, and high reproducibility in mind. In addition to that, however, the two products have their unique niche.
The QSense Pro platform is ideal for large-scale QCM-D analysis, enabling real-time study of molecular interactions at surfaces and interfaces. The platform is designed for automation, it enhances productivity and reproducibility compared to manual instruments. This fully automated system is engineered to maximize efficiency, making it the optimal choice for comprehensive and precise QCM-D analysis.
QSense Omni is the newest member of the QSense family, representing a significant advancement in QCM-D technology. It delivers exceptional performance and data quality, allowing for high-quality and reliable QCM-D data generation. This 4th generation modular and upgradeable instrument suite is designed to simplify and enhance the research process, making it easier for scientists to obtain precise and trustworthy results. In a nutshell, QSense Omni combines automation with flexibility. It also gives you the sharpest QCM-D data and instrument ease of use.
