Why Autosampler Vial Selection Matters
Autosampler vials are often viewed as simple sample containers, but the vial can directly influence analytical results. Glass composition, surface chemistry, manufacturing cleanliness, and packaging methods can affect recovery, stability, adsorption, and reproducibility.
Different applications require different levels of vial performance. Routine HPLC methods may not require the same vial technology needed for LC-MS/MS, biomarker research, peptide analysis, or low-concentration pharmaceutical testing.
MICROSOLV offers multiple vial families designed to address specific analytical requirements, performance expectations, and budget considerations.

RSA™ Autosampler Vials
Reduced Surface Activity for Improved Recovery
Even high-quality glass surfaces contain active silanol groups that can interact with certain compounds. These interactions may contribute to:
- Adsorption
- Chelation
- Sample loss
- pH-related instability
RSA™ (Reduced Surface Activity) vials are designed to reduce these interactions and improve analyte recovery.
Recommended applications include:
- LC-MS/MS methods
- GC-MS analysis
- Basic compounds
- Acid-sensitive compounds
- Low-concentration pharmaceuticals
- Labile analytes
RSA-Pro X™ Autosampler Vials
Maximum Recovery for Challenging Samples
RSA-Pro X™ represents MICROSOLV's most advanced autosampler vial technology.
These vials combine reduced surface activity with enhanced deactivation technologies designed for highly demanding analytical applications.
Typical applications include:
- Biomarker discovery
- Proteomics
- Peptide analysis
- Protein analysis
- Forensic analysis
- Environmental testing
- Ultra-trace analysis
RSA-Pro X™ vials are manufactured without petroleum-based lubricants and are robotically packaged in controlled manufacturing environments to minimize contamination and variability.
