Sep-Pak Alumina N Vac cartridges contain a highly active grade of alumina with a neutral surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica; however, it is slightly more stable than unfunctionalized silica under high pH conditions. This neutral alumina is suitable for applications such as synthetic crude oil fractionation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Reliable Solid Phase ExtractionThe Sep-Pak Alumina N cartridge is tailored for sample purification and preparation under neutral conditions. Its optimal pH operating window (pH 5-8) and ready-to-use design streamline routine laboratory workflows. With a 500 mg sorbent bed housed in medical-grade polypropylene, every cartridge delivers consistent performance for a range of analytical applications.
Ready for Workflow IntegrationThanks to Luer tip and Luer lock compatibility, these vacuum cartridges fit easily into existing vacuum manifold systems. Pre-packed and sealed, they reduce prep time and minimize handling, making them ideal for laboratories requiring scalable, manual solid phase extraction. The compact design facilitates efficient storage and straightforward handling.
FAQ's of Waters Corp Sep-Pak 500 mg Alumina N 3 cc Vac Cartridge and Sorbent per Cartridge:
Q: How do I use the Sep-Pak Alumina N cartridge for solid phase extraction?
A: To use the Sep-Pak Alumina N cartridge, first attach it to a compatible vacuum manifold using the Luer tip or Luer lock connection. Pre-condition the sorbent as per your method, load the sample for extraction, and elute analytes of interest according to your protocol. Ensure the flow rate does not exceed the recommended 10 mL/min.
Q: What is the recommended pH range for optimal cartridge performance?
A: For best results, use the Sep-Pak Alumina N cartridge within a neutral pH range, specifically between 5 and 8. This ensures the alumina sorbent maintains its selective extraction properties and maximizes recovery rates.
Q: When should I select Alumina N sorbent over other types?
A: Choose Alumina N (neutral) when your application requires sample extraction under neutral pH conditions, particularly for analytes that are pH-sensitive or require non-acidic, non-basic sorbent environments. This sorbent is suitable for purification procedures that may be affected by acidic or basic alumina.
Q: Where is the Sep-Pak Alumina N cartridge manufactured and distributed?
A: Waters Corp Sep-Pak Alumina N cartridges are manufactured and distributed through authorized dealers, distributors, exporters, manufacturers, suppliers, traders, and wholesalers throughout India, ensuring access across various laboratory markets.
Q: What benefits does using a vacuum cartridge format offer?
A: Vacuum cartridges like the Sep-Pak Alumina N enable faster sample processing, controlled flow rates, and compatibility with existing manifold systems. Their pre-packed design streamlines workflow without requiring sorbent measuring or packing, reducing handling errors and improving reproducibility.
Q: What are the process considerations for maintaining accuracy and reliability?
A: Accuracy is standardized and controlled per manufacturing lot. For reliable results, follow method protocols precisely, stay within the optimal pH and flow rate recommendations, and use cartridges within their specified capacity (up to 500 mg sorbent per 3 cc cartridge).
