Waters offers various Oasis^® on-line column configurations designed to fit all your on-line analysis needs. These formats are available with the patented Oasis sorbents in a wide choice of particle sizes and dimensions.

The Oasis on-line columns make it possible to analyze a specific analyte in a sample matrix when combined with the appropriate Waters narrow-bore analytical columns, such as XSelect™, XBridge™, SunFire™, Atlantis^®, XTerra^®, or Symmetry^® columns.

• Rugged, reproducible, and ultra-fast on-line analysis
• Compatible with all on-line analysis systems
• Wide choice of configurations, particle sizes, and sorbent chemistries

Waters Oasis^® sorbents are now available in the new 800 series format for use with Spark Holland Symbiosis™ and Prospekt-2™ systems. In contrast to the previous 700 series, the newly designed 800 series cartridge tray can be used directly in the Automatic Cartridge Exchange (ACE) or the ACE Feeder units of the Symbiosis/Prospekt-2 systems without the stainless steel tray holder.

Each narrow-bore PVDF cartridge is available in 1.0 x 10 mm or 2.0 x 10 mm formats. Both of these formats are offered with the five patented Oasis sorbents—HLB, MCX, MAX, WCX, and WAX.

• Cartridge format for use with Spark Holland Prospekt-2/Symbiosis systems
• Narrow-bore PVDF cartridge; available with 2.5 mg of Oasis sorbent in the 1.0 x 10 mm cartridge and 10.4 mg of Oasis sorbent in the 2.0 x 10 mm cartridge
• Available with all five patented Oasis sorbents—HLB, MCX, MAX, WCX, and WAX
• High recovery and reproducible results for a wide range of compounds
