High quality SampliQ SPE (Solid Phase Extraction) products help the user confidently extract and concentrate samples from complex matrices, ensuring fast, accurate, and reproducible results from the very first step. The SampliQ line includes polymers, silica and non-silica options to meet user's specific SPE needs.

The ZORBAX® Bonus-RP column has a polar amide group embedded in a long alkyl chain. This novel bonding reduces interactions between basic compounds and the silica support, improving peak shape for the most difficult basic compounds. Peak shape and column lifetime are further improved by triple endcapping. In addition, diisopropyl side groups provide steric protection against acid hydrolysis for good lifetime and low pH. The Bonus-RP column provides an alternate selectivity to C18 and C8 alkyl bonded phases.

DB-VRX has unique selectivity engineered for optimum resolution of volatiles analysis.

Supplier: Agilent

For applications requiring resolution of argon and oxygen without cryogenic cooling, select columns with thick film. The thin film configurations are ideal for many applications, including routine air monitoring and analysis. The thin film column resolves argon and oxygen at subambient temperatures.

Step 2: Dispersive SPE cleanup
Select the dispersive SPE kit suited to the type of food being analysed and the method you are following. In this step, an aliquot of the sample extract from step one (see QuEChERS extraction kits) is added to a 2 or 15 ml centrifuge tube containing a small amount of SPE sorbent and MgSO₄. The sorbent will pull out interfering matrix materials from the sample, while the MgSO₄ helps remove excess water and improve analyte partitioning.

These columns are recommended for alternate selectivity at low pH relative to Eclipse XDB-C18 and StableBond® SB-C18.

Supplier: Agilent

These columns are with middle range polarity. It is ideal for hydrocarbon analysis, and for resolving acetylene from butane and propylene from isobutane.

Supplier: Agilent

These columns contain (50%-Phenyl)-methylpolysiloxane. They are excellent for confirmation analysis.

Supplier: Agilent

For normal phase chromatography, the ZORBAX® product line offers a choice of bonded and non-bonded silica packings.

Supplier: VICI JOUR RESEARCH

The in-line PEEK guard cartridges extend the life of analytical columns by trapping contaminants from the sample and mobile phase, thereby preventing loss of retention. Only PEEK and titanium contacts the mobile phase and sample. This system is ideal for use with proteins or other biopolymers that may be contaminated or absorbed by steel surfaces.

Supplier: KNAUER

These columns with HPLC phase are perfectly suited to take on routine analyses as well as the most ambitious chromatography tasks.

Supplier: PerkinElmer

The online SPE cartridge has been specially designed for elution to the HPLC column. Dimensions are optimised to combine high extraction capacity with small elution volumes.

Supplier: NEUBERT VOLUME GLASSWAERE

Glass, Empty columns: Yes, Ø int.: 200 mm, Length: 500 mm

Supplier: PerkinElmer

The MPLC cartridge system allows direct coupling of an analytical and NewGuard™ cartridge without introduction of any dead volume. A specific cartridge holder (30, 100, 220 mm) is required for each cartridge length.
