Spectrophotometric determination of chlorine by the “oxygen bomb” method

Spectrophotometric determination of blood oxygen.

Gasometric methods for estimating blood oxygen are time-consuming. This consideration often limits the number of observations which can be made in the course of experiments requiring oxygen determinations. In many cases it is an arteriovenous difference which is particularly desired, as in the measurement of cardiac output by the Fick principle, or the estimation of oxygen consumption by human ...

A simple spectrophotometric method for the determination of blood sugar by phenylhydrazine Hydrochlorlde

multiwavelength pectrophotometric determination of stability constants of 4-(2– thiazolylazo) resorcinol (tar) with la3+, y3+ and th4+ in organic-water mixed solvents by chemometrics method & simultaneous spectrophotometric determination of lead, copper and nickel using xylenol orange by partial least squares calibration method

تشکیل کمپلکس های tarبا یون های لانتانیم, ایتریم و توریم در دمای 25 درجه، قدرت یونی ثابت 0.1 مولار و در ph ثابت در مخلوط حلال های اتانول – آب و استونیتریل – آب با استفاده از روش های اسپکتروفوتومتری مورد بحث و بررسی قرار گرفت. داده های اسپکتروفوتومتری با استفاده از نرم افزار squad پردازش شدند تا ثابت های تشکیل کمپلکس اندیکاتور – فلز را محاسبه کند. نتایج نشان می دهد که درصد حلال آلی در مخلوط حلال ...

The spectrophotometric determination of the oxygen saturation of blood.

ORDY AND DRABKIN (1) have described a simplified spectrophotometric procedure for the determination of oxygen saturation of whole hemolyzed blood. The described method of sampling by use of tonometers, although technically precise, is somewhat inconvenient for routine clinical use. In a note appended to the article, Marsh described a simpler modification. He collects the samples in oiled, hepar...

Spectrophotometric determination of the oxygen saturation of whole blood.

A new approach to the spectrophotometric determination of blood oxygen saturation has been made which is based on the absorption maximum of oxyhemoglobin and the isosbestic point of oxyhemoglobin and hemoglobin. The precision of this new method is comparable to that of the manometric procedure in which the Van Slyke-Neil1 apparatus is employed; there is also good correlation between results obt...
