SPE Disks and Cartridges
Biotage ATLANTIC DISK C18 HC 50MM 24PK
Atlantic high capacity c18 spe disk provides added retention per disk for improved recovery of analytes from higher organic content sampes and improved recovery of compounds that have weaker interactions with c18 media. much like the original atlantic c18, the new high capactiy c18 can be used for drinking water applications such as epa method 525.2.
Waters Corp Sep-Pak Aminopropyl (NH2) 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 55 - 105 µm, 30/pk
Sep-Pak Amino Propyl (NH2) Vac cartridges contain a moderately polar, silica-based bonded phase with weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanges in aqueous medium below pH 8. Applications include extraction of phenols and phenolic pigments, petroleum fractionation, saccharides and drugs and metabolites. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak C8 3 cc Vac Cartridge, 200 mg Sorbent per Cartridge, 37 - 55 µm, 50/pk
Silica-based bonded phase with moderate hydrophobicity; use for methods requiring less retention than C18; typical applications include drugs and their metabolites in serum, plasma or urine, peptides in serum, plasma.
Waters Corp Oasis MCX 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 60 µm, 30/pk
The 6 cc Oasis MCX cartridges contain the Oasis MCX, which is a novel, mixed-mode polymeric sorbent that has been optimized to achieve higher selectivity and sensitivity for extracting basic compounds with cation-exchange groups. Since the Oasis MCX sorbent is water wettable, it maintains its capability for higher retention and excellent recoveries even if the sorbent runs dry, which means there is no need to take extraordinary steps to keep the sorbent beds from drying out during the critical steps prior to sample loading. The 60 µm particle size is recommended when working with viscous samples. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Certified Sep-Pak Alumina N 3 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Certified 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. Certified Sep-Pak Alumina N cartridges are quality controlled to ensure reproducible separations. The cartridges provide superior performance for ultra-low level analyte detection by reducing the potential for background interferences found in many SPE devices. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Sep-Pak C8 35 cc Vac Cartridge, 10 g Sorbent per Cartridge, 37 - 55 µm, 10/pk
Silica-based bonded phase with moderate hydrophobicity; use for methods requiring less retention than C18; typical applications include drugs and their metabolites in serum, plasma or urine, peptides in serum, plasma.
Waters Corp Sep-Pak Florisil 6 cc Vac Cartridge, 500 mg Sorbent per Cartridge, 50 - 200 µm, 30/pk
Florisil is an extremely polar sorbent that is a blend of magnesium oxide and silica gel. This highly active and weakly basic sorbent is used to adsorb low to moderate polarity species from nonaqueous solutions. Florisil is commonly used for pesticide analysis in many AOAC, EPA, and JPMHLW regulated methods for food and environmental samples.
Hach Company Xenomax Triple-layer SPE Filters, 47 mm, 24/PK
Designed for moderately dirty samples, Xenomax™ Solid-Phase Extraction (SPE) Filters for EPA Method 1664A provide maximum recovery, speed and particulate loading capacity. Chemically treated with a proprietary reverse phase adsorbent, triple layer borosilicate glass Xenomax™ SPE Filters (47mm) can filter the 40 mg/L EPA PAR standard in approximately 20 seconds with similar filtration times for 1-L NPDES-type samples. Xenomax™ SPE Filters provide maximum analyte recovery, particulate loading capacity and processing speed when used with Xenosep SPE Glassware.
Waters Corp Sep-Pak Aminopropyl (NH2) 20 cc Vac RC Cartridge, 500 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Sep-Pak Amino Propyl (NH2) Vac RC cartridges contain a moderately polar, silica-based bonded phase with weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanges in aqueous medium below pH 8. Applications include extraction of phenols and phenolic pigments, petroleum fractionation, saccharides and drugs and metabolites. These cartridges feature an integral 20 cc funnel-shaped reservoir for convenient processing of larger volumes of samples. They can be used with robotic sample preparation equipment or with vacuum manifolds.
Waters Corp Sep-Pak Cyanopropyl (CN) 6 cc Vac Cartridge, 1 g Sorbent per Cartridge, 55 - 105 µm, 30/pk
Silica-based polar bonded phase; can be used as less polar alternative to silica in normal-phase applications or as less hydrophobic alternative to C18 or C8 in reversed-phase applications; typical applications include drug metabolites and pesticides.
