Analyst Approved
- Qualifiers: B - Analyte detected in the associated Method Blank, value not subtracted from result Definitions: NA - Not Applicable
E - Extrapolated value.Value exceeds calibration range LQL - Lower Quantitation Iamit
H - Sample analysis exceeded analytical holding time Sue - Surrogate
I -Indicates an estimated value when the cartQewnd is detected, but is below the LQL
S - Spike Recovery outside accepted limits
U - Compound analyzed for but not detected
X - See case narrative
