The term is most often used in the context of bioburden testing, also known as microbial limit testing, which is performed on pharmaceutical products and medical products for quality control purposes. Products or components used in the pharmaceutical or medical field require control of microbial levels during processing and handling. Bioburden ...
A chloridometer is a measuring instrument used to determine the concentration of chloride ions (Cl –) in a solution.It uses a process known as coulometric titration or amperostatic coulometry, the accepted electrochemistry reference method to determine the concentration of chloride in biological fluids, including blood serum, blood plasma, urine, sweat, and cerebrospinal fluid.
The predicted no-effect concentration (PNEC) is the concentration of a chemical which marks the limit at which below no adverse effects of exposure in an ecosystem are measured. PNEC values are intended to be conservative and predict the concentration at which a chemical will likely have no toxic effect. They are not intended to predict the ...
A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

In analytical chemistry, the detection limit, lower limit of detection, also termed LOD for limit of detection or analytical sensitivity (not to be confused with statistical sensitivity), is the lowest quantity of a substance that can be distinguished from the absence of that substance (a blank value) with a stated confidence level (generally 99%).
An arbitrary limit of 10 metres has been adopted. The target values shown below are for 'shallow' groundwater, 0 – 10 m depth. The soil remediation intervention values indicate when the functional properties of the soil for humans, plants and animals is seriously impaired or threatened.

On the other hand, if you consider HIC as a chemical (indicating spot) on a paper card (indicator) the consequence is that it should be considered as a preparation, the concentration limit changes to 0.01% weight of cobalt(II) chloride, and it should be labeled as T (toxic) and R49 (may cause cancer if inhaled).
