Why Autosampler Vial Selection Matters

Autosampler vials are far more than simple sample containers. The glass composition, surface chemistry, manufacturing quality, cleanliness, and packaging methods can directly affect:

• Analyte recovery
• Sample stability
• Adsorption and sample loss
• Method reproducibility
• LC-MS sensitivity
• Quantitative accuracy

As analytical methods become more sensitive, the choice of vial becomes increasingly important. A vial that performs well for routine HPLC may not be suitable for UHPLC, LC-MS/MS, biomarker discovery, peptide analysis, or ultra-trace pharmaceutical applications.

MICROSOLV offers six distinct autosampler vial families designed to address different analytical requirements, performance expectations, and laboratory budgets.

BASIK™ Autosampler Vials

AQ™ Autosampler Vials

Enhanced Cleanliness for UHPLC and Mass Spectrometry

AQ™ Autosampler Vials were developed specifically for applications where cleanliness and contamination control are critical.  As instrument sensitivity increased, trace contaminants originating from sample containers became increasingly important. AQ™ vial technology helps address those concerns through enhanced cleanliness standards and controlled packaging.

Best suited for:

• UHPLC methods
• LC-MS
• LC-MS/MS
• GC-MS
• Trace-level analysis
• High-sensitivity testing

Benefits Include:

• Reduced manufacturing residues

• Protected packaging systems

Choose AQ™ When:

• UHPLC or mass spectrometry is being used.
• Trace contamination must be minimized.
• High analytical sensitivity is required.

RSA™ Autosampler Vials

Reduced Surface Activity for Improved Recovery

Many analytes interact with active silanol groups naturally present on glass surfaces.

These interactions may contribute to:

• Adsorption
• Sample loss
• Lower recoveries
• Inconsistent quantitative data
• Reduced stability for sensitive compounds

RSA™ (Reduced Surface Activity) technology is designed to minimize these surface interactions.

Best suited for:

• Basic compounds
• Acid-sensitive analytes
• Low-concentration pharmaceuticals
• LC-MS/MS methods
• Labile compounds
• Adsorption-prone samples

Choose RSA™ When:

• Surface interactions are affecting results.
• Sample recovery is critical.
• Low-level quantitation is important.
• Basic analytes are being analyzed.

RSA-Pro X™ Autosampler Vials

Maximum Recovery for Challenging Analytical Applications

RSA-Pro X™ represents MICROSOLV's most advanced glass vial technology.  Combining reduced surface activity with enhanced deactivation processes, these vials are designed for the most demanding analytical methods where every percentage of analyte recovery matters.

Best suited for:

• Biomarker discovery
• Proteomics
• Peptide analysis
• Protein analysis
• Forensic applications
• Environmental analysis
• Ultra-trace detection

Additional Advantages

• Enhanced deactivated surfaces
• Controlled manufacturing environments
• Robotic packaging systems
• No petroleum-based lubricants

Choose RSA-Pro X™ When:

• Maximum analyte recovery is required.
• Protein and peptide losses must be minimized.
• Ultra-trace analysis is being performed.
• The highest-performing glass vial system is needed.

Selecting the Right Vial Improves Analytical Results

The autosampler vial is one of the first surfaces your sample encounters and can significantly influence final analytical results.

Choosing the proper vial can help improve:

• Recovery
• Precision
• Accuracy
• Stability
• Method robustness
• Instrument sensitivity

The optimal vial depends on the complexity of the sample, the sensitivity of the analytical method, and the performance expectations of the laboratory.

Whether your laboratory performs routine HPLC, pharmaceutical testing, LC-MS/MS analysis, metabolomics, proteomics, or ultra-trace research, MICROSOLV offers a vial technology designed to support your application.
