SPE Sorbents Products & Reviews

CLEAN SCREEN FASt THC is the newest sorbent in our FASt product lineup. It employs a process that uses positive pressure and a solid phase sorbent bed built with small pore frits to quickly and efficiently prepare urine samples for LC/MS analysis. This method eliminates timely centrifugation, reduces matrix suppression effects, and removes particulates greater than ~1μm. Samples can be diluted at a ratio as low as 1:1, which i…

Clean Screen® ETG is a proprietary carbon blend column designed for the extraction of ethyl-glucuronide from urine.  Extracts are suitable for either GC/MS or LC/MS analysis.

CLEAN SCREEN FASt EtG is the newest sorbent in our FASt product lineup. Similar to the other products in the FASt line, it employs a process that uses positive pressure and a solid phase sorbent bed built with small pore frits to quickly and efficiently prepare urine samples for LC/MS analysis. This filtration device helps to combat the significant ion suppression EtG/EtS urine analysis typically suffers from using a standa…

Designed to retain excess organometallic catalysts commonly utilized in industrial synthesis enabling purification by simple filtration. 

Solid Phase Extraction (SPE) is the basis of analytical laboratories. A crucial step of this process is sample preparation. Therefore we know that a clean sample will yield better results. To achieve this goal SiliCycle has designed SiliaPrep, which is a silica based sorbent exempt of fines, and SiliaPrepX, polymeric based sorbent, that can be found in cartridges, well plates and SPME (Solid Phase Micro-Extraction) cartridges…

Functional groups, such as octyl (C8) and octadecyl (C18), can be bonded to the silica surface to provide non polar interactions.  Each of these sorbents exhibits unique properties of retention and selectivity for a particular analyte.  The choice of which sorbent is best for a particular method will be influenced by the percent recovery of analyte from the sample matrix and the cleanliness of the resulting chromatography.

This mixed phase chemistry, in which two primary modes of attraction are present, allows for a more efficient and selective extraction compared to traditional reversed phase techniques.  Neutral and ionized analytes can be simultaneously extracted from a complex mixture and eluted as separate fractions.  A mixed phase sorbent offers the following advantages: Eluting acidic and neutral analytes separately from basic analy…

This chemistry promotes high retention of a wide range of analytes, reducing method development time and facilitating a generic approach to sample preparation.

Empore Filter Aid 400 has been shown to improve flow rates and recoveries for separation and filtration of water samples containing suspended solids.  When placed on top of the Empore™ Extraction Disk at a depth of about 1 cm, Empore™ Filter Aid 400 acts as depth filter to inhibit the migration of suspended solids to the surface of the disk.  This reduces extraction time and improves rates and recovery of analytes.

Versatile polymeric material for retention of polar and non-polar analytes • Exceptional recoveries for polar and non-polar analytes • High and consistent recoveries • High capacity material • Fast and easy sample preparation method development • pH stable 0-14 HyperSep Retain PEP (polar enhanced polymer) is a high purity, highly porous polystyrene DVB material modified with urea functional groups to give balanced retention of…
