SPE columns, ISOLUTE® ENV+

Supplier: Argonaut Technologies

ISOLUTE® ENV+ is a hyper crosslinked hydroxylated polystyrene-divinylbenzene copolymer, with very high surface area, ideal for extracting polar analytes from large volume water samples. The particle size and retentive nature of the sorbent allow exceptionally high sample flow rates to be used without reducing extraction efficiency or analyte recovery.

SPE columns, ISOLUTE® C2

Supplier: Argonaut Technologies

ISOLUTE® C2 is a weakly non-polar sorbent for extraction of non-polar acidic, neutral and basic analytes from aqueous samples using a non-polar retention mechanism. It is used for the extraction of non-polar acidic, neutral and basic compounds from aqueous sample matrices. Secondary silanol interactions can be exploited to enhance extract purity and method robustness for basic analytes.

Sorbents for column chromatography, ISOLUTE® MSPD

Supplier: Argonaut Technologies

Matrix solid phase dispersion is a sample preparation technique for use with solid sample matrices. Two MSPD grade ISOLUTE sorbents, MSPD C18 and MSPD C18(EC) have been developed by Argonaut and is particularly applicable to the extraction of basic veterinary drugs from liver and other biological matrices. These sorbents produce a more homogeneous and rapid blend of the matrix-sorbent mixture compared with SPE or preparative grade C18 sorbents.

SPE columns, ISOLUTE® SCX-2

Supplier: Argonaut Technologies

ISOLUTE® SCX-2 is a propylsulphonic acid based strong cation exchange sorbent with minimal non-polar character. It is used for retention of basic compounds from aqueous samples. These sorbents manufactured using a trifunctional silane and non-endcapped. Analytes are eluted from these columns by eliminating the charge on the analyte (high pH), so this sorbent is not suitable for extraction of strong bases.

SPE columns, ISOLUTE® C8(EC)

Supplier: Argonaut Technologies

ISOLUTE® C8 endcapped is primarily used to extract molecules of wide ranging polarities from aqueous samples. When analytes are strongly retained by a C18 sorbent, the slightly weaker interaction with the C8(EC) can facilitate analyte elution with smaller elution volumes. It is a non-polar sorbent, manufactured using a silane and endcapped in order to reduce the polar secondary interactions associated with surface silanol groups.

SPE columns, ISOLUTE® C8

Supplier: Argonaut Technologies

ISOLUTE® C8 has the broad range of polarity from a aqueous matrix as it has the combination of both strong primary (non-polar) and secondary (silanol) interactions. To provide additional polar interactions associated with surface silanol groups the sorbent is not endcapped. C8 sorbent is less retentive than C18 when retention is based solely on non-polar interactions. The surface silanols are more available for secondary interactions compared with the non-endcapped C18.

SPE columns, ISOLUTE® MFC18

Supplier: Argonaut Technologies

ISOLUTE® MFC18 is a retentive, non polar sorbent for extraction of a range of analytes from aqueous samples using a non polar retention mechanism. It is used for extraction from aqueous matrices using non polar interactions (for acidic, neutral and basic analytes) and readily accessible secondary silanol interactions (for basic compounds only). Not the ideal choice when working at extremes of pH, due to its relatively low carbon load.

Sample processing manifolds, VacMaster™ 10 and 20

Supplier: Argonaut Technologies

These robust manifolds are constructed from high quality, inert materials (glass, PTFE and PE), eliminating sample contamination and allowing all common solvents and buffers to be used. System allows up to 10 (VacMaster™ 10) or 20 (VacMaster™ 20) SPE or filtration columns to be processed simultaneously under vacuum. Unused ports are sealed when not required. Easy to use vacuum controls provide excellent sample flow control, leading to reproducible, reliable extraction conditions.
