mgLrange

mgLrange is a label used in some scientific datasets and instrument outputs to denote the range of concentrations, expressed in milligrams per liter (mg/L), that applies to a measurement, sample, or calibration. The unit mg/L represents mass of solute per liter of solution, and the term range indicates bounds rather than a single value. In practice, mgLrange may appear as a field containing two numbers representing the lower and upper concentration limits (for example, 0.2–2.0 mg/L) or as a structured pair in a data record.

Applications of mgLrange span environmental monitoring, water quality analysis, and process control. It helps document the reporting window, detection capabilities, or calibration span of an assay or sensor. For instance, a nitrate sensor might include mgLrange 0.05–5.0 mg/L to indicate the reliable measurement interval, while readings outside this interval may be flagged as out of range or require dilution.

Interpretation and data integrity considerations are important. Users should confirm the precise definition of mgLrange within a given dataset, including whether the range refers to reported results, method detection limits, or instrument calibration bounds. It is also important to distinguish mg/L from related conventions such as nitrate-nitrogen (NO3–-N) concentrations, which may use different reporting units or conversion factors.
