A new method of carboxyhaemoglobin determination.

چکیده
A quick and accurate method of determining the concentration of carboxyhaemoglobin (COHb) in blood has been developed. The method uses a dual wavelength double beam spectrophotometer in the 1st derivative mode, linked to a digital voltmeter (DVM), with the two beams set 3 nm apart around an isobestic point of reduced haemoglobin (Hbred) and carboxyhaemoglobin at 579 nm. The 1st derivative mode measures the slope, and this slope is proportional to the concentration of COHb.

A colorimetric method for the determination of carboxyhaemoglobin over a wide range of concentrations.
A colorimetric technique for the determination of carboxyhaemoglobin in blood is described. Carbon monoxide released from blood in a standard Conway unit reacts with palladous chloride/arsenomolybdate solution to produce a blue colour. Using 0.5 to 2 ml. of blood, the method will estimate carboxyhaemoglobin accurately at levels from 0.1% to 100% of total haemoglobin and in the presence of other...
متن کاملDetermination of the carboxyhaemoglobin saturation of blood by spectrophotometric analysis.
The spectrophotometric method of Commins and Lawther (I965) for the determination of carboxy-haemoglobin saturation in blood was found to lead to systematic undervaluation, because of dissociation of the carboxyhaemoglobin, and physical dissolution of the carbon monoxide in the solvent used for the analysis. The theoretical relationship between the true and apparent carboxyhaemoglobin saturatio...
متن کاملA Sensitive Method for the Determination of Carboxyhaemoglobin in a Finger Prick Sample of Blood.
About 0-01 ml. of blood taken from a finger prick is dissolved in 10 ml. of 0-04% ammonia solution. The solution is divided into two halves, and oxygen is bubbled through one half to convert any carboxyhaemoglobin into oxyhaemoglobin. The spectra of the two halves are then compared in a spectrophotometer, and the difference between them is used to estimate the carboxyhaemoglobin content of the ...
متن کاملCarboxyhaemoglobin and plasma thiocyanate: complementary indicators of smoking behaviour?
Carboxyhaemoglobin and plasma thiocyanate concentrations were measured in 79 non-smokers and 360 cigarette smokers. The mean levels were 0.73% and 7.09% carboxyhaemoglobin and 40 . 2 and 133 . 8 mumol thiocyanate/1 plasma respectively. With 1 . 6% carboxyhaemoglobin and 73 . 0 mumol thiocyanate/1 plasma as critical values the concentrations of carboxyhaemoglobin in 96.6% of subjects and of thio...
متن کاملA Study of Determination of Exhaled Carbon Monoxide and Carboxyhemoglobin in School Children
Background: carbon monoxide (CO) may play a role in pathophysiology of airway diseases. School children are at risk of exposure to environmental smoke. Adequate data regarding are not available. The measurement of exhaled CO level may provide an immediate, non-invasive method of fractional concentrations of CO in expired air. Exhaled CO levels & Carboxyhaemoglobin (COHb) reflects the exposure t...
