Choosing the Right Vials
- Needle Design
- Draw-port Location
- Autosampler Tray Design
- Robotics
- Venting
Factors such as detection method, mobile phase, analyte structure and volatility play an important role in determining the appropriate vial and septa for your application. To aid you in choosing the appropriate product, we have outlined the strengths and weaknesses for the various materials of construction used in manufacturing sample vials and septa to help you choose the appropriate product.
Vials are the least expensive component of your HPLC system, but can be the biggest contributor to problems that you encounter such as:
- Mechanical problems
- Sample draw volume reproducibility
- Septum dislodging or coring
- Injector damage / Robotics malfunction
- Excessive residual sample volumes
- Chemical problems
- Evaporative loss
- Extra peaks / extractables
- Sample / analyte degradation
