    Introduction

    Solid phase extraction (SPE) is one of the most used techniques in sample preparation. It is replacing the conventional time-consuming liquid-liquid extraction (LLE) method. The process of SPE is a miniature version of liquid column chromatography. SPE, utilizing the same type of stationary phases as used in liquid chromatography columns, are practiced in different mechanisms including normal phase, reversed phase, ion-exchange, affinity chromatography and mixed-mode in the fields of agricultural and food, bio-analytical, environmental, and forensic applications.

    The Meizheng family of solid-phase extraction (SPE) products are designed to simplify and improve your sample preparation by combining the right sorbent chemistry, device format and methodology.

    We provide PuriTestTM and PloyplusTM these series included bonded silica series sorbent, no-silica absorption sorbent and polymer sorbent which are designed to meet all your sample preparation needs.

    Classification

    Bonded Silica SPE: PuriTestTM

    Silica,C18,C8,NH2,PSA,PH,SAX,SCX,ect.

    Silica based SPE series are made of high quality and low metal contents silica particles. Using the special surface modification methodology, the activity of silica surface is reduced, which will reduce the tailing of basic compounds and ensure high recovery and reproducibility. Such as C18, C8, NH2, and PSA etc.

    No-silica Absorption SPE: PuriTestTM

    Florisil, GCB, Alumina (Neutral, Acid, Basic).

    They are commonly used to remove polar interference from non-polar samples. They are widely used in sample preparation for environmental and food analyses.

    Polymer SPE: PloyplusTM

    HLB, MAX, MCX, WAX, WCX and PS

    Based on polystyrene/divinylbenzene, and each phase has different functionality and unique selectivity. They are highly recommended for the extraction of a wide

    range of compounds in pharmaceutical, agricultural, food, and environmental industries.

    Storage andDisposal

    Cartridges stored in their original sealed pouch remain stable for long periods. Once opened, special care must be taken to ensure that the SPE cartridges are not exposed to the laboratory environment for long periods. The highly active sorbents will readily accumulate background contaminants from the environment and will affect the quality of the device. Meizheng recommends that you open and use only those cartridges that will be needed. If this is not possible, store the exposed cartridges in clean contaminant free container such as a desiccator.

    Dispose of used cartridges safely in accordance with applicable government or local regulations.
