Volatile Organic Data Review

Initial Calibration

1.8

Are the relative response factors for the Calibration

List the response factors that are out of compliance and the

Check Compounds (CCCs) within acceptable limits of

%RSD. List all affected sample IDs:

%RSD?

Note: The relative standard deviation criteria for stability is:

%RSD < 15% for all analytes except for CCCs where the

relative standard deviation criteria is: %RSD < 30%. CCCs are

considered to be “poor performers,” and are singled out for

evaluation with the idea that if they are within acceptable

criteria then other compounds are also likely acceptable. The

CCCs are:

1,1-Dichloroethene

Chloroform

Toluene

1,2-Dichloropropane

Ethylbenzene

Vinyl Chloride

Action: If %RSD > 30% for any CCC, then the lab should have

taken action to eliminate system leaks and/or column reactive

sites before attempting re-calibration.

If the analysis was performed and the %RSD < 15% in the initial

calibation for compounds other than CCCs, qualify positive results

for those analytes as “J ” and un-detected analytes as “R.”

When %RSD > 90%, flag all non-detects for that analyte as “R.”

Prior to analysis of samples, the tuning criteria of the instrument must be evaluated by injection of a 5ng to 50ng aliquot of 4-

Bromofluorobenzene into the instrument. In addition, the initial calibration must be verified every twelve hours by analyzing a calibration

standard (referred to as a 12-hour standard or sometimes an Initial Calibration Verification (ICV) or a Continuing Calibration Verification

(CCV)) near the mid-point of the calibration curve. System Performance Check Compounds (SPCC) in this standard must be examined

every twelve hours and meet the criteria listed in the above table. Calibration Check Compounds (CCC), also in the ICV and/or CCV, must

be examined to determine the validity of the initial calibration. These compounds must meet the criteria listed in this table. If problems

are encountered, a new 5-point calibration should be performed.
