Direct, Reliable, and Correct Oxygen Measurement

چکیده
Oxygen-dependent quenching of phosphorescence has been used extensively for the last 25 years as a reliable method for measuring oxygen. Major strengths of the method are that it is noninvasive, except for the phosphor, and calibration is absolute. Because it is an optical method, oxygen can be measured through the walls of optically clear chambers. The method’s absolute calibration means that there is no requirement for recalibrations at the time of the experiment with similar experimental conditions or oxygen concentrations. Phosphorescence lifetime measurements are not affected by other chromophors or fluorescence.

متن کاملI-15: Effects of Oxidative Stress on Sperm Function
Semen analysis is the frontline and old reliable test in the assessment of male fertility, but it failed to provide absolute prediction of sperm function and its fertilizing ability. A wide variety of internal and external factors affect sperm function without discernible and significant effects on semen analysis. Oxygen toxicity and oxidative stress (OS) are inherent challenge of living cells ...

متن کاملThe Value of Bilicheck® as a Screening Tool for Neonatal Jaundice in the South of Iran
The gold standard to assess jaundice in neonates is the serum bilirubin measurement. Blood sampling for the determination of total serum bilirubin (TSB) is painful for newborns and stressful for parents. The Bilicheck®, a new transcutaneous bilirubinometer, is considered as a more accurate measurement of bilirubin compared to the previous bilirubinometers courtesy of its advanced technology. Th...
