Sample Preparation

SHIMSEN Styra Na2SO4 is a special dehydrating column filled with anhydrous sodium sulfate.

SHIMSEN Styra Glass is developed specifically for high-purity extraction and suitable for detection on ppt level. The inert glass tube completely eliminates contamination from plasticizers, such as phthalates. The sorbent and the specially cleaned sieve plate used in SHIMSEN Styra glass cartridge are all high-grade to ensure stability and repeatability.

SHIMSEN Styra SAX/PSA is packed with 2 layers of anion exchange packing to enhance the removal of anionic impurities in samples. It is widely used in the analysis of multiple pesticide residues in food.

SHIMSEN Styra GCB/PSA and SHIMSEN Styra GCB/NH2 are mixed sorbent SPE cartridges consisting of carbon black particles (GCB) and silica gel particles bonded with PSA or NH2 group. The GCB can remove pigments, while PSA and NH2 can remove anionic compounds. They are mainly used for the analysis of multi-pesticide residues in food samples.

SHIMSEN Styra GCB is packed with planarized carbon, mainly used to remove pigment components from crops. The polarity and ion exchange property of this cartridge are used to purify all kinds of sample substrates. The typical application of this cartridge is the analysis of pesticide residues in agricultural products. Plant samples often contain various pigments, such as chlorophyll, lutein, carotenoids, etc, which need to be removed in order to eliminate its interference with the analysis results and experimental instruments.

SHIMSEN Styra SAX is a trimethylaminopropyl-bonded silica cartridge and has strong anion exchange functionalities.It can provide selective retention for anionic organic compounds (such as compounds containing carboxyl groups and phenolic hydroxyl groups). The non-polar interactions are weak due to its short carbon chain on the quaternary ammonium group.

SHIMSEN Styra SCX is a propyl benzenesulfonate bonded silica cartridge and has strong cation exchange functionalities. The presence of the benzene ring in the functional group increases its nonpolar characteristics. Besides, SHIMSEN Styra SCX is suitable for the separation of basic compounds.

SHIMSEN Styra Ph is a phenyl-bonded silica cartridge. It has the same non-polar interaction as C8, and also has the unique - electron pair interaction due to phenyl. It is a good choice for sample preparation when C8 could not provide the desired selectivity. And it has good selectivity for aromatic compounds with benzene ring.

SHIMSEN Styra C2 is an ethyl bonded silica cartridge and has weaker non-polar interation compared to C8. It is an excellent replacement for C8 when highly hydrophobic compounds are too strongly retained for effective elution. Highly endcapping of this sorbent inhibits secondary interactions caused by silanol groups, resulting in less adsorption of basic compounds. It is an excellent replacement for C8 and C18 when analytes are too strongly retained for effective elution.

SHIMSEN Styra C8 is an octyl bonded silica cartridge and has weaker non-polar interation compared to C18. C8 is an excellent replacement for C18 when highly hydrophobic compounds are too strongly retained for effective elution. Highly endcapping of this sorbent inhibits secondary interaction caused by silanol groups, resulting in less adsorption of basic compounds.
