Spinach Matrix Removal Capacity of CarbonX for QuEChERS compared to GCB
Spinach Matrix Removal Capacity of CarbonX for QuEChERS compared to GCB Introduction: Graphitized Carbon Black (GCB) is generally added to QuEChERS dispersive solid phase extraction (dSPE) kits when the food extract is highly pigmented. This is due to the fact that pigments and sterols cause fouling of the liner and column as well as decreased signal to noise when quantitating samples on GC/MS and LC/MS/MS systems. CarbonX for QuEChERS greatly reduces the losses of planar pesticides observed with GCB sorbents. In [...]
