PQL definition
Examples of PQL in a sentence
PQL This field contains the practical quantitation limit for each chemical compound, as determined by the laboratory.
The PQL is used for the qualified result(s) to calculate the average.
For parameters that are not amenable to MDL studies, the PQL may be defined by the sample volume and buret graduations for titrations or by minimum measurement values set by the method for method-defined parameters (e.g., BOD requires a minimum DO depletion of 2.0 mg/L, fecal coliform requires a minimum plate count of 20 cfu, total suspended residue requires a minimum weight gain of 2.5 mg, etc.).
Contracts that do not exceed $1 Million that are awarded pursuant to prequalified lists (PQLs) established by City agencies where entry on to the PQL is restricted to MWBEs, or a combination of MWBEs together with joint ventures which include at least one MWBE, or contractors who agree to subcontract at least 50% of the contract to MWBEs.
Determination of PQL is fully described in the laboratory’s analytical Standard Operating Procedure (SOP) document.
Alternative limits for detection and quantitation other than MDL and PQL shall be determined, if applicable to the laboratory.
Contracts that do not exceed $1 Million that are awarded pursuant to prequalified lists (PQLs) established by the Agency where entry on to the PQL is restricted to MWBEs, or a combination of MWBEs together with joint ventures which include at least one MWBE, or contractors who agree to subcontract at least 50% of the contract to MWBEs.
Aircraft landing GPT, BIX, PQL, or HSA, operating above FL280, must cross the common ZHU/ZTL boundary at or below FL280 right altitude for direction of flight.
Sampled, but analysis lost or not performed-lab error Y Elevated PQL* due to insufficient sample size Z The presence or absence of the analyte cannot be verified.
PQL The Practical Quantitation Limit (PQL) is defined as the lowest concentration that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operating conditions.
