solid phase extraction, including manifold, vacuum as well as automated solid
phase extraction equipment, well compatible with RayKol automated solid-phase
extraction systems. RayCure SPE cartridges utilize high-quality sorbents to
ensure the efficiency of SPE clean up, offers full range of SPE cartridges for
various sample matices. Strict quality managment and control ensures high
recovery rate of analytes and experiment reproducibility. RayKol provides
effective, efficient and economial SPE cartridges with high performance.

SPE CARTRIDGE TYPES

RayCure SPE Column
RayCure SPE series provide pre-packed SPE columns with a variety of sorbents,
resins and cartridge size for various methods and target analytes.

RULES TO SELECT RAYCURE SPE CARTRIDGE TYPES
Rule I:

The properties of solid phase packing in SPE cartridges should be match to
target compounds.

Rule II:

Take the advantage of differences between analytes of interest and
interferences

Rule III:

Consider nature of SPE sample matrices, characteristics of analytes and
solubility of used solvents

Users can select RayCure SPE columns depending on properties of desired
analytes and sample matrices as following selection guides.

HOW DOES SPE COLUMN WORK?

SPE is a conventional and efficient extraction technique, it uses the affinity
of solutes dissolved or suspended in mobile phase for stationary phase to
separate desired compounds from a mixture. And there are two solid phase
extraction mechanisms to obtain target analytes from complex samples, to retain
desired compounds in stationary phase or retain impurities in solid phase.
Depending on the difference of two mechanisms, SPE procedures could be a bit
various.

When sample portion passes through SPE column, undesired impurities are
discarded with mobile phase, target compounds are retained in stationary phase,
then rinse stationary phase with eluents to collect target compounds. It is the
most commonly used purification mechanism of solid phase extraction.



In the opposite, to retain impurities in stationary phase, target compounds and
few impurities are collected in mobile phase when sample portion passes through
SPE column. Rinse the stationary phase which impurities is retained with
solvents to obtain rest of retained target compounds. This mechanism is mostly
used to eliminate fat-soluble impurities of ion analysis and analysis of
multiple pesticides in fruits and vegetables.
