SHIMSEN Styra SPE - Features
Solid Phase Extraction Products
Sorbent selection by matrix and analyte
When selecting an SPE phase, it should be consistent with the properties of the analytes. It is also necessary to consider the characteristics of the sample matrix and analytes and the solubility of the solvent used.
Lineup of SHIMSEN Styra SPE by retention mechanism
Solid phase extraction sorbent can be divided into reverse phase, normal phase, ion exchange and mixed mode according to chemical properties. Multiple products are available for each separation mode.
| SPE Phase Type | |||||
|---|---|---|---|---|---|
| Reverse Phase | Normal Phase | Ion Exchange | Mixed Mode | Others | |
| Analyte | Nonpolar Compound | Polar Compound | Ionizable Compound | Ionization Nonpolar Compound | - |
| Sample Matrix Type | Polar | Nonpolar | Aqueous, Nonpolar, etc. | Aqueous, Nonpolar, etc. | - |
| Mechanisms | Reverse phase sorbent is used to extract analytes from aqueous samples using a non-polar (hydrophobic) retention mechanism. | Normal phase sorbent is used to extract analytes from non-polar (typically solvent) matrices using polar retention mechanisms. | Ion exchange sorbent is used to extract ionizable analytes from aqueous samples using an ion exchange retention mechanism. | Mixed mode sorbent is used to extract ionizable analytes from aqueous or nonpolar samples using an ion exchange retention mechanism combined with a non-polar retention mechanism. | - |

Fast Solvent Elution Time
Every step (preconditioning, loading, washing, and eluting) within a SPE procedure is imperative, and it is typically necessary to pass the solvent forcibly using aspiration or pressurization. However, the SHIMSEN Styra SPE cartridge has a high flow rate and does not require aspiration or pressurization, saving time. In this experiment, the solvent elution time (i.e., the time required for 200 µL of methanol to flow through under gravity) was compared between a SHIMSEN cartridge and five commercially available SPE cartridges. The SHIMSEN Styra SPE required only 34 seconds. In contrast, with SPEs from other companies, the solvent elution time ranged from 61 to 150 seconds, and most of them exhibited significant variability.
PFAS Analysis
SHIMSEN Styra WAX and SHIMSEN Styra WAX/GCB can be used for PFAS analysis in compliance with ISO 21675, EPA 1633, and the Japanese Water Supply Act.
Shown below are the results of a recovery study in which PFOA, PFOS, and PFHxS (final concentration: 5 ng/L) were spiked into tap water and tested in accordance with Japan’s Water Supply Act. For all analytes, all lots showed recoveries of 90% or higher, demonstrating good reproducibility. Please refer to the application note below for the sample preparation procedure and analytical conditions.
For the results of PFAS analysis using two different SPE cartridges—SHIMSEN Styra WAX and SHIMSEN Styra WAX/GCB—please access the application note listed below.

Proper Packing
The products are individually packaged in air-tight bags in small quantities to reduce degradation caused by air and to prevent interference between products.
