LCS = Laboratory Control Samples. LCS at each concentration level were run once and the range of individual recoveries and their mean and RSD are reported. CCVBVNA = Continuing calibration verification standard: 50 ng/mL FU run periodically during the sample queue. Five spiked sorbent tubes were prepared for each concentration. Average recovery for each concentration was determined and the recovery range of these values is reported, along with the mean and RSD of these averages.
