Sep-Pak C18 Plus Light Cartridge, 130 mg Sorbent per Cartridge, 55-105 µm, 50/pk

Add the Sep-Pak C18 Plus Light Cartridge to your lab equipment collection to be able to conveniently transfer your solvents, solutions, and samples with ease after extracting them. The cartridge enables you to perform this task without any worries about spillage or sample loss due to evaporation. As it is a precision chromatographic tool for sample enrichment and purification, the Sep-Pak C18 Plus Light Cartridge is the ideal lab equipment.

A silica-based bonded octadecyl phase with strong hydrophobicity is used in the Sep-Pak C18 Plus Light Cartridge. This makes it ideally suited to adsorb analytes of even weak hydrophobicity from aqueous solutions. The Sep-Pak C18 Plus Light Cartridge is versatile and can be used across a wide range of applications. These include drugs and their metabolites in serum, plasma, or urine, desalting of peptides, trace organics in environmental water samples, organic acids in beverages. In addition to this, the cartridge is similar in behavior to reversed-phase HPLC columns, so can be used for sample enrichment and purification as well.

The integrity of the Sep-Pak C18 Plus Light Cartridge can be relied upon. The lab equipment’s integrity is maintained throughout its manufacturing cycle and delivery by sealing it in a specially designed, non-contaminating poly-foil pouch that has been designed to maintain product integrity, packing inactivity, and purity until the package is opened in your lab.

Waters ensures that only the highest quality packings are used in the manufacturing of the Sep-Pak C18 Plus Light Cartridge. The packing material has been designed and made specifically for sample preparation, and is clean, dry, and reproducible in both activity and capacity. Using this high-quality packing, Sep-Pak C18 6 cc Vac Cartridge is able to offer optimal surface area, pore-size, particle-size distributions.

As the Sep-Pak C18 Plus Light Cartridge uses a blend of HD and UHMW polyethylenes for the 20 µm frit in the design, it has solvent resistance, very low extractable levels, and good flow properties. The frit also performs the function of a depth filter that retains small amounts of sample debris.

Sep-Pak C18 Plus Light Cartridge, 130 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk FAQs

1. What is the particle size range of the sorbent in this cartridge?
The Sep-Pak C18 Plus Light Cartridge contains sorbent particles ranging from 55 to 105 µm in size. This particle size range is chosen to balance optimal flow rates with effective retention and separation of target compounds, particularly suited for small to medium-scale extractions and purifications.

2. How should I store unused Sep-Pak C18 Plus Light Cartridges?
Unused Sep-Pak C18 Plus Light Cartridges should be stored in a cool, dry place away from direct sunlight and moisture to preserve sorbent integrity. If possible, store them in their original, sealed packaging to prevent contamination and exposure to environmental factors that might affect their performance.

3. How does the Sep-Pak C18 Plus Light Cartridge differ from standard Sep-Pak C18 cartridges?
The Sep-Pak C18 Plus Light Cartridge is designed with a smaller sorbent mass (130 mg), which makes it ideal for lighter sample loads and precise applications where lower analyte quantities are used. It's often chosen for applications requiring high sensitivity, where sample volume and sorbent interaction need to be closely controlled.

4. What is the recommended pH range for using the Sep-Pak C18 Plus Light Cartridge?
The Sep-Pak C18 Plus Light Cartridge is optimized for a pH range of 2 to 8. Operating within this range helps maintain the sorbent's stability and performance, ensuring consistent analyte retention and recovery. Extreme pH levels outside this range could damage the C18 bonded phase, reducing the cartridge's effectiveness.
