e-Chronicle – September 2025
Your Chromatography Update – Sample Preparation
In this month's e-Chronicle Newsletter, we've featured a variety of Sample Preparation-related topics, including new products, green initiatives, instrumentation, technical resources, and more!
CSI is now using the 12 point SIGNIFICANCE mnemonic to assess greener analytical chemistry technology.
NEW PRODUCTS
Restek – Resprep PFAS Cartridges
A Two-in-One Solution for PFAS SPE Sample Preparation.
- Single cartridge with both WAX and carbon beds simplifies workflows.
- Factory-packed filter aid saves time and prevents clogs.
- Ultra-clean sorbents ensure MDLs are met.
- Tested to ensure accurate and precise results.
Green Chemistry:
ntegrate analytical processes – filtration and extraction.
enerating as little waste as possible – 60% less He use.
Restek – Resprep FL + CarboPrep SPE for Pesticides
In soil and water samples for organochlorine pesticides, co-extracted matrix components can contaminate the inlet and column.
- Increases time required for maintenance, including unplanned maintenance.
-
Pass-through SPE using Florisil cartridges is common.
- Florisil captures polar contaminants, but not high molecular weight contaminants that foul GC inlets.
- CarboPrep Plus is extremely efficient at removing high MW components.
- Columns last longer and instruments stay running, which increases sample throughput and lab profitability.
Green Chemistry:
ncreasing safety for operator.
enerating as little waste as possible.
FEATURED PRODUCT
