The LCS % recovery data is used for <br />1f -OP— validation of sample batch results. Due to matrix effects, the QC limits for MS/MSD's are advisory only <br />Linda C. Schneider and are not used to accept or reject batch results. <br />Project Manager/Sacramento Laboratory <br />6100675.ENV <4> <br />T4 <br />
