The phrase "a single tracer" is correct and usable in written English.
It can be used in contexts where you are referring to one specific tracer, such as in scientific, technical, or gaming discussions.
Example: "In the experiment, we used a single tracer to track the movement of the particles."
Alternatives: "one tracer" or "a lone tracer".
At dusk, a single tracer bullet was seen fired from the lifeboat.
Isotope-labeling experiments can be conducted as a single tracer experiment, or as parallel labeling experiments.
When Seung started, he estimated that it would take a single tracer roughly a million years to finish a cubic millimeter of human cortex — meaning that tracing an entire human brain would consume roughly one trillion years of labor.
However, using a single tracer, such as [18F]TFAHA, it is hard to determine the degree to which a single dose of MC1568 may influence BBB permeability or perfusion and, thus, the delivery of [18F]TFAHA in 9L gliomas.
The technique of positron emission particle tracking (PEPT), developed at Birmingham, whereby a single tracer particle can be tracked at high speed, has proved particularly powerful.
Positron Emission Particle Tracking (PEPT) is a powerful technique and capable of following a single tracer accurately and non-invasively in flow and mixing processes.
Compared to previous models [ 4, 7– 13], our method is very robust, relying on only a single tracer-specific parameter \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\bar{\betaa } $$\end{document }
The first option involves a single-tracer design with the addition of more independent measurements.
By integrating labeling data from such parallel labeling experiments, fluxes can be resolved at a high resolution that can never be achieved using any single tracer experiment.
This still needs a validation for every single tracer, every single scanner, and each acquisition and data analysis protocol separately.
One design relies on the detection of a single resident tracer over multiple domains within the PFM cross section to determine the magnitude and direction of water flux.
