Solid-Phase Extraction Products & Reviews

This chemistry promotes high retention of a wide range of analytes, reducing method development time and facilitating a generic approach to sample preparation.

Functional groups, such as octyl (C8) and octadecyl (C18), can be bonded to the silica surface to provide non polar interactions.  Each of these sorbents exhibits unique properties of retention and selectivity for a particular analyte.  The choice of which sorbent is best for a particular method will be influenced by the percent recovery of analyte from the sample matrix and the cleanliness of the resulting chromatography.

This mixed phase chemistry, in which two primary modes of attraction are present, allows for a more efficient and selective extraction compared to traditional reversed phase techniques.  Neutral and ionized analytes can be simultaneously extracted from a complex mixture and eluted as separate fractions. A mixed phase sorbent offers the following advantages: Eluting acidic and neutral analytes separately from basic analyt…

SDB-XC is a poly(styrenedivinylbenzene) copolymer used as a reversed phase sorbent for solid phase extraction.  SDB-XC is not bonded to silica but is a 100% copolymeric particle that is spherical, porous and cross-linked.  It does not exhibit the secondary cationic (silanol) interactions and pH limitations common to bonded silica sorbents, so it offers more predictable and reproducible reversed phase interaction.

The Empore™ High Performance Extraction Disk Plate differs in design from plates offered by other manufacturers and requires a specific vacuum manifold.  Manifolds supplied by different plate manufacturers are specific to the design of their plates and cannot generally be used with plates from other manufacturers.  In some cases, the use of spacers to raise/lower the height of a collection device inside the manifold may overco…

Replacement gaskets are available with the vacuum manifold assembly.  The gasket can become worn over time and the seal between the plate and the manifold will be affected.  This may result in poor vacuum pressure and negatively effect flow rates.  The gasket should be checked regularly and replaced when it becomes worn.

Empore Filter Aid 400 has been shown to improve flow rates and recoveries for separation and filtration of water samples containing suspended solids.  When placed on top of the Empore™ Extraction Disk at a depth of about 1 cm, Empore™ Filter Aid 400 acts as depth filter to inhibit the migration of suspended solids to the surface of the disk.  This reduces extraction time and improves rates and recovery of analytes.

Spark has introduced the second edition of HySphere™ C8 End-Capped cartridges. We have selected a new perfect Spherical sorbent material with a narrow particle size distribution. This will create less back pressure during operation and allows you to run higher flow rates compared to our current HySphere™ C8 (EC). The new cartridge has the same excellent characteristics such as high extraction capacity and selectivity

DisQuE Dispersive Sample Preparation is a well proven, high throughput sample preparation method for a wide array of pesticides in produce. The kit contains conveniently packaged vials with pre-measured sorbents and buffers used to provide extraction and clean-up for up to 100 samples. Each 50 mL DisQuE Extraction tube contains 6 grams of magnesium sulphate and 1.5 grams of sodium acetate. Each 2 mL DisQuE Clean-Up tube cont…

Symbiosis™ Pharma is Spark Holland's unique solution for integrated online SPE-LC-MS automation (XLC-MS). The heart of the matter in XLC-MS, is where the autosampler injects at a controlled temperature, raw bio-fluids directly on a fresh disposable SPE cartridge. The small particle sorbent assures a clean extract, a very high sensitivity and reliable results. Online elution to the LC-MS cuts the number of sample prep steps in…

MEPS (patent pending) performs the same function as SPE, namely the purification or speciation of samples, but with some significant differences: MEPS works with much smaller samples (as small as 10µL) than full scale SPE MEPS can be fully automated – the sample processing, extraction and injection steps are performed on-line using the same syringe MEPS is applicable to GC and LC Significantly reduces the volume of solvents an…
