However, GCB may cause the loss of some analytes. Carbon S is an advanced hybrid carbon material with optimized carbon content and pore structure. Compared to GCB, Carbon S provides equivalent or better pigment removal from sample matrices, while significantly improving recovery for some GCB-selective analytes (such as planar pesticides). As a result, Carbon S sorbent provides a better balance between analyte recovery and matrix removal efficiency than traditional GCB sorbent. The Carbon S sorbent is applied in the same SPE cartridge format with the same bed mass as GCB SPE. The Carbon S SPE cartridges can be used as a replacement for the GCB cartridges for applications where SPE methodology is used. This study investigates the post-extraction matrix cleanup of 59 PFAS from loamy sand, reed sedge peat, and topsoil using the Bond Elut Carbon S 250 mg, 6 mL cartridges followed by LC/MS/MS analysis.

These compounds have more than 200 congeners, and seventeen of them are highly toxic and of interest in trace analysis. Historically, these analyses have been performed using magnetic sector high-resolution GC/MS. In 2021, the U.S. EPA approved an alternate testing protocol (ATP) that accepts GC/TQ as an equivalent technology for the analysis of dioxins in environmental samples.  This work shows the Agilent triple quadrupole GC/MS system can achieve the sensitivity required to meet and exceed guidance for the analysis of PCDD/PCDFs at all concentration levels.

Agilent Spectroscopy instruments are ideal for monitoring these substances—whether naturally occurring or the result of industrial or agricultural activity—because they can provide robust performance and precise quantitative analysis of trace level inorganics.
