In d-SPE, an aliquot of sample extract is added to a ,centrifuge, tube containing a relatively small amount of SPE sorbent and the mixture is shaken to increase distribute the SPE material and facilitate the clean-up process. Next, centrifugation of the sample enables separation of the sorbent and an aliquot of nascent supernatant can be analyzed.

One such scale is the relative standard deviation (,RSD,) or the coefficient of variance (CV), which is a ratio of standard deviation to the arithmetic mean of the replicate analyses and expressed as a percent: ,RSD, = ( s x )100% In Examples 1 and 2, the RSDs are as follows: 0.29 mg/L × 100% = 5.4% 5.3 mg/L 2.86 mg/L × 100% = 5.4% 53 mg/L
