The liquid limit test is defined by ASTM standard test method D 4318. [4] The test method also allows running the test at one moisture content where 20 to 30 blows are required to close the groove; then a correction factor is applied to obtain the liquid limit from the moisture content. [5]
Toxicity characteristic leaching procedure (TCLP) is a soil sample extraction method for chemical analysis employed as an analytical method to simulate leaching through a landfill.
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.
Traditionally “Cation Conductivity” instruments are used to analyze steam quality, but in addition to measuring harmful ionic compounds (e.g. chloride ions), they also include CO 2, which as stated above is not significantly harmful to the steam turbine. Furthermore, typical cation conductivity analyzers take 3–4 hours to provide useful ...
Validation of analytical procedures is imperative in demonstrating that a drug substance is suitable for a particular purpose. [5] Common validation characteristics include: accuracy, precision (repeatability and intermediate precision), specificity, detection limit, quantitation limit, linearity, range, and robustness.

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.
