TECHNICAL FLAGS FOR MANUAL INTEGRATION<br />

Manual quan modifications or integrations are performed routinely to improve <strong>the</strong> data quality<br />

for a variety <strong>of</strong> technical reasons. Documentation <strong>of</strong> <strong>the</strong>se modifications should be clear and<br />

concise. The following `flags' are used to indicate <strong>the</strong> technical reasons for quan modifications:<br />

MP - Missed Peak: Manually added peak not found by automatic quan<br />

program.<br />

PA - Peak Assignment: Quan report was changed to reflect correct peak<br />

assignment.<br />

RI - Routine Integration: Routine integrations are performed for some<br />

analytes that are consistently integrated improperly by <strong>the</strong> automatic<br />

integration programs. Examples are <strong>the</strong> Dichlorobenzene isomers on <strong>the</strong><br />

VOA packed column and Benzo (b) fluoran<strong>the</strong>ne /Benzo (k) fluoran<strong>the</strong>ne<br />

which are poorly resolve on <strong>the</strong> BNA column.<br />

SP - Split Peak: The automatic integration improperly split <strong>the</strong> peak; a manual<br />

integration was performed to get <strong>the</strong> correct area.<br />

CB - Co-elution/ Background: Peak was manually integrated to eliminate<br />

contribution from co-eluting compounds, background signal, or o<strong>the</strong>r<br />

interference.<br />

PI - Proper Integration: A peak with poor or inconsistent integration (i.e.,<br />

excessive tail) was properly integrated manually.<br />
