Sample Preparation

The original and most referenced based SPE products Separation scientists like you would like to achieve highly reproducible Solid-Phase Extraction (SPE) results, and Sep-Pak sample extraction products were designed to help you do just that. Waters Sep-Pak cartridges and plates enable speed and selectivity while simplifying the HPLC, GC, and LC-MS sample preparation process. All Sep-Pak sample extraction products contain high quality sorbents. They are available in more than 200 chemistries and format combinations for convenient sample preparation methods, based on reverse-phase, normal-phase, ion-exchange, and application-specific specialty chemistries. Whether your sample type includes chemical, environmental, food, or biological analytes, Waters has a Sep-Pak sample extraction product to meet your workflow requirements. Sep-Pak devices are available in many styles to accommodate manual and automated solid-phase extraction. Devices are available in syringe barrels, 96-well plates, and Plus cartridge formats. The newest Plus cartridges consist of double Luer-lock adaptors that enable secure Luer-locking connection without the concern of dislodgement due to high back pressure whereas used in the automatic equipment.

QuEChERS fast and easy sample preparation for residual analysis Rapidly and easily screening large numbers of food and agricultural samples is vital for your organization. Waters QuEChERS kits for dispersive solid-phase extraction (d-SPE) analysis make sample prep quick and easy for your multi-residue food and agricultural analysis. Waters DisQuE d-SPE products include conveniently packaged centrifuge tubes and foil pouches containing pre-weighed extraction buffer salts for use with the Association of Official Analytical Chemists (AOAC) or European Committee for Standardization (CEN) QuEChERS sample preparation methods. The extracts can be cleaned up with a flexible selection of dispersive SPE (d-SPE) targeting specific sample matrix. View more products

Faster, cleaner, and simpler SPE starts here Analytical chemists worldwide use SPE to remove interfering matrix compounds and enrich the analyte of interest to ensure the generation of high-quality data. Waters Oasis SPE products come in a broad range of sorbents and an array of formats. With Oasis products, you can meet a wide variety of sample preparation needs, from simple and fast sample matrix clean-up to more complex sample preparation challenges. Oasis SPE products deliver unmatched purity, consistency, and quality for sample analysis. Along with seven different SPE chemistries, Oasis SPE products use universal to customized protocols to handle your unique sample. View more products

Extraction and concentration without the low background contamination Per- and polyfluoroalkyl substances (PFAS) are a growing environmental concern. Now your lab can extract and concentrate PFAS without worrying about low background contamination through the power of Oasis SPE for PFAS Analysis, a comprehensive quality-control pre-screening test for 32 PFAS. Oasis WAX for PFAS Analysis is a mixed-mode, Weak Anion-eXchange, reversed-phase, water-wettable polymer that delivers unmatched purity, consistency, and quality for sample analysis in drinking water, ground water, soil, food, and other complex matrices. With growing regulatory concerns for PFAS contamination in complex sample matrices, Oasis WAX/GCB for PFAS Analysis can be used for non-potable water samples, and Oasis GCB/WAX for PFAS Analysis for solids, biosolids, and tissue sample enrichment, providing an additional level of graphitized carbon black clean-up as described in EPA Draft Method 1633. Designed specifically for environmental testing laboratories, these solid-phase extraction products enable you to perform low level quantification of ubiquitous PFAS in environmental samples.

Fast, simple, and cost effective synthesis cleanup Waters offers PoraPak Rxn, a family of polymer-based chromatography products for superior cleanup of synthetic reactions. PoraPak Rxn products are available in two chemistries: PoraPak Rxn CX, a strong cation-exchange sorbent and PoraPak Rxn RP, a reversed-phase sorbent. PoraPak Rxn sorbents are based on copolymers that exhibit the following properties: Hard material that does not develop increasing back pressure with flow Little swelling or shrinking across a range of solvents and pH extremes Low hydraulic resistance enables flow by gravity pH extreme tolerance without dissolution or hydrolysis, both limitations of silica-based sorbents View more products

Clear, high-throughput in-well protein precipitation starts here Saving time and improving efficiency in your lab is critical. One way to do that is to streamline your sample handling process by eliminating the time-consuming sample handling steps of traditional protein precipitation (PPT). The Sirocco Plate is the most technologically advanced 96-well protein precipitation plate on the market. With its unique membrane and valve-tip technology, you can carry out high-throughput in-well protein precipitation of biological samples without fear of cloudy filtrates or clogged devices. You can also speed processing time with Sirocco's optimum performance, which enables you to simplify in-well sample processing and complete recovery of clean filtrates from smaller plasma sample volumes.
