Overview
RSA™ (Reduced Surface Activity) glass was developed to provide an optimized sample contact surface for sensitive chromatography applications. The technology is designed to minimize unwanted sample interactions while maintaining the dimensional consistency required for autosampler performance.
At this time, RSA™ glass is available only in standard 12 × 32 mm autosampler vial formats and is not manufactured in glass tube configurations.
RSA™ Glass Availability
Current RSA™ glass products are limited to:
- 12 × 32 mm autosampler vials
RSA™ glass is not available in:
- Glass tubes
- Microtubes
- Alternative vial dimensions
- Custom tube formats
Laboratories requiring RSA™ glass performance should select from the available RSA™ autosampler vial configurations.
Benefits of RSA™ Glass
RSA™ glass is designed for applications where sample integrity and low surface activity are important considerations.
Benefits may include:
- Reduced analyte interaction with glass surfaces
- Improved sample recovery
- Enhanced consistency for sensitive analyses
- Low background contribution from the vial surface
These characteristics make RSA™ vials particularly useful for demanding chromatographic workflows.
Alternative for Other Vial Sizes
For applications requiring vial sizes or formats not available in RSA™ glass, RSA-Pro X™ products may be an appropriate alternative.
RSA-Pro X™ utilizes a proprietary surface treatment technology designed to provide:
- Hydrophobic surface properties
- Reduced sample interaction
- Improved recovery of adsorption-prone compounds
- Compatibility with a variety of vial configurations
Because RSA-Pro X™ technology is available on additional vial formats, it may provide a solution when RSA™ glass is unavailable in the required size.
Selecting the Best Option
Choose RSA™ Glass when:
- A 12 × 32 mm autosampler vial format is suitable
- Reduced surface activity glass is required
- Maximum compatibility with RSA™ technology is desired
Consider RSA-Pro X™ when:
- Alternative vial sizes are needed
- Surface treatment technology is acceptable
- Additional vial configurations are required
Key Takeaways
- RSA™ glass is available only in 12 × 32 mm autosampler vials.
- RSA™ glass tube formats are not available.
- The technology is designed to reduce surface activity and support sensitive chromatography applications.
- RSA-Pro X™ products may be suitable alternatives when other vial sizes are required.
- RSA-Pro X™ technology is available on a broader range of vial configurations.
