Minimum Level (ML definition

Minimum Level (ML means the concentration at which the entire analytical system must give a recognizable signal and an acceptable calibration point. The ML is the concentration in a sample that is equivalent to the concentration of the lowest calibration standard analyzed by a specific analytical procedure, assuming that all the method-specified sample weights, volumes and processing steps have been followed.
Minimum Level (ML means either the sample concentration equivalent to the lowest calibration point in a method or a multiple of the method detection limit (MDL). Minimum levels may be obtained in several ways: They may be published in a method; they may be sample concentrations equivalent to the lowest acceptable calibration point used by a laboratory; or they may be calculated by multiplying the MDL in a method, or the MDL determined by a lab, by a factor.
Minimum Level (ML means the lowest concentration of an analyte that can be accurately and precisely quantified using a given method, as determined by the laboratory.

Examples of Minimum Level (ML in a sentence

  • Dischargers are to instruct laboratories to establish calibration standards so that the Minimum Level (ML) value (or its equivalent if there is differential treatment of samples relative to calibration standards) is the lowest calibration standard.

  • Where the permit contains a Minimum Level (ML) and the permittee is granted authority in the permit to report zero in lieu of the < ML for a specified parameter (conventional, priority pollutants, metals, etc.), then zero (0) is to be reported for that parameter.

  • For purposes of reporting and administrative enforcement by the Central Coast and State Water Boards, the Discharger shall be deemed out of compliance with effluent limitations if the concentration of the reportable pollutant in the monitoring sample is greater than the effluent limitation and greater than or equal to the reported Minimum Level (ML).

  • Definitions for a reported Minimum Level (ML) and Method Detection Limit (MDL) are provided in Attachment A.

  • The Discharger shall report with each sample result the applicable reported Minimum Level (ML) and the current Method Detection Limit (MDL), as determined by the procedure in Part 136.

Minimum Level (ML means the level at which the entire analytical system gives recognizable mass spectra and/or acceptable calibration points. This level corresponds to the lowest point at which the calibration curve is determined based on analyses for the pollutant of concern in reagent water. The ML for a gas chromatographic-mass spectrometry method or inductively coupled plasma-mass spectrometry method is based on both mass spectra and acceptable calibration points. The ML for methods that do not use mass spectrometry for pollutant confirmation and/or have no published ML in the method documentation is based on the method detection limit (MDL) and minimum level (ML) determinations as described in Section 9.3.1.1 of “Protocol for EPA Approval of New Methods for Organic and Inorganic Analysis in Wastewater and Drinking Water” (EPA 821-B-98-003, March 1999).
Minimum Level (ML means either the sample concentration equivalent to the lowest calibration point in a method or a multiple of the method detection limit (MDL), whichever is higher. Minimum levels may be obtained in several ways: They may be published in a method; they may be based on the lowest acceptable calibration point used by a laboratory; or they may be calculated by multiplying
Minimum Level (ML means either the sample concentration equivalent to the lowest calibration point in a method or a multiple of the method detection limit (MDL), whichever is higher. Minimum levels may be obtained in several ways: They may be published in a method; they may be based on the lowest acceptable calibration point used by a laboratory; or they may be calculated by multiplying the MDL in a method, or the MDL determined by a laboratory, by a factor of 3. For the purposes of NPDES compliance monitoring, EPA considers the following terms to be synonymous: “quantitation limit,” “reporting limit,” and “minimum level.”
