A phenomenological expression for the ion current is
The in-cylinder pressure-based and the ion current signal analyses has been compared with high spatial and temporal resolution optical data on a cycle resolved basis.
The overlay of the total ion current (TIC) suggests the analysis is very reproducible between injections.
The unit also includes Meech's Ion Current Monitoring technology (ICM).
In these devices a modulation in a baseline ion current can be observed when DNA or a biomolecule is translocated through the nanopore.
To resolve these difficulties, ULVAC has developed an ionization vacuum gauge with a structure designed to lighten the load on ion collectors by reducing the ion current value per area and to make electric potential in ionized space uniform.
For example, the limit of detection or quantification in targeted selected reaction monitoring measurements is limited either by the selected peptide ion current or by the presence of interfering ions from such sources as coeluting species or "chemical noise.
This occurs when a voltage is applied across a membrane, setting up an ion current.
A biopotential electrode is a transducer that senses ion distribution on the surface of tissue, and converts the ion current to electron current.
This leads to major performance improvements in mass spectrometers such as better mass resolution and accuracy and a 10x improvement in dynamic range whether measuring a sustained ion current, a burst of ions, or a very large isolated peak of ions.
Content includes information on such topics as ion distribution and ion current regulation.
The system also provides real-time information on neutralizer efficiency, ion current flowing to the charged material, and system diagnostics.
