titration

 [ti-tra´shun]
determination of a given component in solution by addition of a liquid reagent of known strength until a given endpoint, e.g., change in color, is reached indicating that the component has been consumed by reaction with the reagent.
Dean and Webb titration a test for measuring antibody in which varying dilutions of antibody are mixed with a constant quantity of antiserum; antibody activity is determined by the dilution in which flocculation occurs most rapidly, i.e., the end point.

For this method 50[micro]L of 0.8% [R.sub.1][R.sub.2] titration Indicator cells (NZBS Reference Laboratory) and 25[micro]L of each master dilution were added to individual wells in a Diamed (now Biorad) Liss/ Coombs card.
Two of the patients in the re-titration group restarted clozapine in hospital but were discharged early to continue the titration in the community under the care of the crisis team.
Karl Fischer Titration has long been the method of choice for water content determination, mainly due to fast analysis times, accuracy, repeatability, chemical selectivity to the water molecule, and simple operation.
A review of existing methods for the determination of sulfate ion yields several possibilities titration methods [10-12], but not IR-turbidimetric.
We use the volume (20.00 mL) and concentration of [Na.sub.2][B.sub.4][O.sub.7] to calculate the amount of [Na.sub.2][B.sub.4][O.sub.7] used in the titration:
Britton Robinson buffer was prepared by known method Amperometric titration were made on SYSTRONIC 1634 polarograph at 1.15 V as SCE An Elico digital pH meter 269 was used with glass and calomel electrode assembly Experimental sets, each having known amount of Se, & Te in appropriate quantity of BR buffer of pH 5.80 at u = 0.2 were prepared.
The frequency of vital sign monitoring should be determined by the specific medication being infused, the half-life of the medication and the titration. If you read the manufacturer's instructions for each medication it will give you information on monitoring.
Four different titration values were examined (0.2, 0.5, 1.0, and 2.0 s).
A decision-analysis model was used to estimate the effectiveness and cost-effectiveness of a number of HAT screening-treatment algorithms; different HAT confirmation test sequences were compared, including concentration techniques and CATT titration. Decision analysis is a method that quantifies the value of several alternative options in a complex choice.
The technique involves heating of the polymer in an oven, carrying the total amount of volatile matter (including moisture) into a reaction vessel by dry nitrogen, titrating the moisture coulometfically by KF titration technique, leaving the other volatile matter un-reacted.
