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.
Methanol is most often used as the solvent, but ethylene glycol and diethylene glycol also work. Pyridine is often used to prevent the buildup of sulfuric acid, although the use of imidazole and diethanolamine for this role are becoming more common. All reagents must be anhydrous for the analysis to be quantitative. The balanced chemical ...
Several laboratory methods are then used to determine the sodium and chloride concentrations. Before this method of inducing sweat was developed, the method was to place the entire person to be tested in a hemispherical chamber and slowly raise the humidity and temperature of the air inside.

The normal range may vary slightly from lab to lab. Normal ranges are usually shown next to results in the lab report. A diagnostic test may use a chloridometer to determine the serum chloride level. The North American Dietary Reference Intake recommends a daily intake of between 2300 and 3600 mg/day for 25-year-old males.
Almost all model kits on the market were plastic, necessitating paints (the square, glass Testor paint bottles were sold in almost every dime store, department store, hardware store, toy store and hobby store in the US in the 1960s, making them truly ubiquitous) and glues different from those used for wooden models.
Alijah Martin scored 18 points, Denzel Aberdeen added 16 and No. 8 Florida thumped top-ranked Tennessee 73-43 on Tuesday night to knock off the last unbeaten team in Division I basketball. Alex ...
A Büchner funnel is a piece of laboratory equipment used in filtration. [1] It is traditionally made of porcelain, but glass and plastic funnels are also available. On top of the funnel-shaped part there is a cylinder with a fritted glass disc/perforated plate separating it from the funnel.
