چکیده
Coulometric tit.ratio~ provides a si~ple and accurate means to ca librate microvolumet ri c appara tus such as burets, mICroplpets, and syrInges. The apparatus to be calibrated is caused to deliver a solution of know? concentration into an electrolysis cell where it is analyzed coulometri cally. By the method descnbed, volumes ranging from 300 ILl to I ILl have been calibrated with relative standard deviation of 0.03 to 3 percent , respectively.

The coulometric determination of glucose in human serum.
The coulometric titration method is combined with the use of an enzymatic analytic reagent for the determination of glucose in human serum. The glucose in 25 ii. of serum is determined in a protein-free filtrate (PFF) with an accuracy of ± 3% and a coefficient of variation of approximately 2%. The procedure routinely covers a concentration range of 25-250 mg/100 ml. Calibrations are linear to a...
متن کاملDetermination of Vitamin C (Ascorbic Acid) Using High Performance Liquid Chromatography Coupled with Electrochemical Detection
Vitamin C (ascorbic acid, ascorbate, AA) is a water soluble organic compound that participates in many biological processes. The main aim of this paper was to utilize two electrochemical detectors (amperometric - Coulouchem III and coulometric - CoulArray) coupled with flow injection analysis for the detection of ascorbic acid. Primarily, we optimized the experimental conditions. The optimized ...

متن کاملCoulometric Sensurs, the Application of a Sensor- Aci’uato3% System for Long-term Stability in Geemical S~s~~*
We present a new type of chemical transducer, the co~orn~~c sensor, This sensor is in fact an integrated sensor-actuator system that is able to measure the concentration of acids and bases by means of a coulometric titration. An ISFET is used as the sensor to monitor the pH changes induced by the actuator, which is a gold electrode that fits closely around the ISFET’s gate area. Coubmetry is an...
