Waters Corp Waters Sep-Pak Cartridge, DNPH-Silica, 800 mg, 55–105 μm, 20/pk
The Sep-Pak DNPH-Silica Plus Long Cartridge is designed for analyzing formaldehyde, other aldehydes, and ketones in air. It meets EPA Method TO-11A, JPM HLW, and ISO 16000 requirements, making it an excellent device for sample collection. Air is redirected through the cartridge using a vacuum pump, allowing ketones and aldehydes to react with DNPH, forming hydrazone derivatives. These hydrazones can then be eluted with acetonitrile for sample analysis.
- Provides low background for higher sensitivity.
- Saves time and increases productivity.
- Offers superior convenience and reproducibility, ideal for field sampling and process monitoring.
- Reduces solvent consumption, solvent exposure, and hazardous waste disposal costs.
- Supports high-speed, high-resolution UPLC Technology applications for excellent quantitation capability in the low parts-per-billion range.
Waters Corp Sep-Pak Accell Plus QMA Plus Light Cartridge, 130 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Sep-Pak Accell Plus QMA Plus Light cartridges contain a silica-based, hydrophilic, strong anion-exchanger with large pore size (300Å). The cartridges are designed for extraction of anionic analytes in aqueous and non-aqueous solutions. The large pore size makes it ideal for isolation of larger molecules such as anionic proteins such as immunoglobulins and enzymes. Other applications include isolation of phenolic compounds and removal of acidic pigments in wine, fruit juices, and food extracts. These cartridges have a distinctive finned outer body and a reduced internal diameter, which results in an interstitial volume about one-third that of the corresponding Plus-style cartridge. This design allows you to elute fractions in a minimal volume to improve recoveries and reduce solvent consumption, a benefit especially for applications where samples are limited or where excessive dilution is a concern.
