A LED-based phosphorimeter for measurement of microcirculatory oxygen pressure.
Guerci P, Ince Y, Heeman P, Faber D, Ergin B, Ince C. Guerci P, et al. J Appl Physiol (1985). 2017 Feb 1;122(2):307-316. doi: 10.1152/japplphysiol.00316.2016. Epub 2016 Dec 8. J Appl Physiol (1985). 2017. PMID: 27932672 Free article.
This study presents the design and calibration process of an LED-based phosphorimeter (LED-P). The in vitro calibration of the LED-P using palladium(II)-meso-tetra(4-carboxyphenyl)-porphyrin (Pd-TCCP) as a phosphorescent dye is presented. ...

Pharmacodynamic study of polyethylene glycol conjugated bovine hemoglobin (PEG-bHb) in rats.
Bi Z, He X, Zhang X, Jiang Y, Zhao K, Liu Q. Bi Z, et al. Artif Cells Blood Substit Immobil Biotechnol. 2004 May;32(2):173-87. doi: 10.1081/bio-120037826. Artif Cells Blood Substit Immobil Biotechnol. 2004. PMID: 15274427
Tissue oxygenations of rats were evaluated by the oxygen dependent quenching of phosphorescence using an Oxyspot phosphorimeter, and the results showed that capability of oxygen-delivery of PEG-bHb was close to autogenous blood and superior to dextran 70. ...

A deoxygenation system for measuring protein phosphorescence.
Banks DD, Kerwin BA. Banks DD, et al. Anal Biochem. 2004 Jan 1;324(1):106-14. doi: 10.1016/j.ab.2003.09.022. Anal Biochem. 2004. PMID: 14654052
The oxygen-free gas was routed through stainless steel tubing directly into the sample compartment of the phosphorimeter. Flexible tubing, coupled to the stainless steel tubing, was run through the septum of a cuvette sealed with a gray butyl rubber lyophilization stopper. …

Calibration of Pd-porphyrin phosphorescence for oxygen concentration measurements in vivo.
Sinaasappel M, Ince C. Sinaasappel M, et al. J Appl Physiol (1985). 1996 Nov;81(5):2297-303. doi: 10.1152/jappl.1996.81.5.2297. J Appl Physiol (1985). 1996. PMID: 8941557 Free article.
For in vivo application, the dye is coupled to albumin to restrict the dye to the circulation and to measure oxygen in the physiological range. In this study a phosphorimeter with a gated photomultiplier is presented and validated. Furthermore, a nonlinear-fit method using …

Direct screening of tetracyclines in water and bovine milk using room temperature phosphorescence detection.
Traviesa-Alvarez JM, Costa-Fernández JM, Pereiro R, Sanz-Medel A. Traviesa-Alvarez JM, et al. Anal Chim Acta. 2007 Apr 18;589(1):51-8. doi: 10.1016/j.aca.2007.02.063. Epub 2007 Mar 3. Anal Chim Acta. 2007. PMID: 17397652
Those chelates are then on-line retained on a conventional flow-cell (packed with polymeric Amberlite XAD-4 particles) which is placed inside the cell holder of the phosphorimeter. After the emission is registered, the antibiotic-metal complexes are eluted from the packed …

Pulsed-source time-resolved phosphorimetry: comparison of a commercial gated photomultiplier with a specially wired ungated photomultiplier.
Persvik Ø, Melø TB, Naqvi KR. Persvik Ø, et al. Photochem Photobiol Sci. 2013 Jun;12(6):1110-3. doi: 10.1039/c3pp50050k. Epub 2013 Mar 15. Photochem Photobiol Sci. 2013. PMID: 23503741
When a photomultiplier tube (PMT) is used as the photosensor in a pulsed-source phosphorimeter, two options are open to an experimenter who finds mechanical shutters inconvenient or impracticable and photon counting inappropriate: apply an electronic gate that suppresses t …
