Presence or absence of the analyte cannot be verified. <br /> UJ=Not detected above reported quantitation limit. However,the reported quantitation limit is approximate due to issues identified in case narrative or data validation reports. <br /> Y=Sample exhibits fuel pattern which does not resemble standard. <br /> Z=Sample exhibits unknown single peak or peaks. <br /> Page 9 of 9 <br /> 25970308.xis 08/22/00 <br />
