DPX-Qg For Removal of Chlorophyll |
|
An acetonitrile solution of spinach was prepared according to the QuEChERS procedure by shaking spinach with acetonitrile in a 1:1 ratio (10 g spinach with 10 mL acetonitrile). Then 1 mL of the acetonitrile solution was dispensed into 2 test tubes, one that is untreated and the other which is "cleaned up" by aspirating and dispensing the solution in and out of the DPX-Qg tip 3 times. Note the removal of the green pigment by the DPX-Qg tip, which contains "high quality" graphitized carbon black (GCB). This is a very new GCB material that is of the highest quality for removing plant pigment matrices, which may have deleterious effects on the GC inlet system.

Cleanup Tips (patent pending) are DPX tips that are used to remove sample matrix components rather than extract and isolate the analytes of interest. The methods for these tips are much faster because the extractions do not require any wash or elution steps. Simply mix the sample solution with the sorbent and dispense--within seconds the solution is ready for chromatographic analysis. Here are some examples of cleanup tips and their methods of use:
