This can be due to (1) a rate response setting that is too sensitive, (2) tracking of atrial noise (such as what may occur with electromagnetic interference), (3) inappropriate pacemaker mani... WebIn these cases, we increase the protection circuit current value of the PMT module from ~6uA to ~50uA. We do this because while some sudden pulses may be high, the average current is still low, and therefore the PMT is still safe. So the H7422PA-40, for example, is a PMT module with an increased protection circuit from ~6uA to ~50uA. home insurance west hills ca

"WebOptimizing photomultiplier tube sensitivity for improved data quality. PMT sensitivity is also controlled by the amount of voltage applied to it, and this needs to be optimized for a given PMT on a given instrument with a given configuration. One of the most common methods for doing this is the ‘Peak 2’ method (Maecker and Trotter (2006)). " - Pmt sensitivity

WebTypical PMT sensitivity settings for luminescence and fluorescence mode are different. When measuring luminescent reactions, the PMT sensitivity setting used is higher than typically used for fluorescence. Recommended PMT settings in fluorescence are generally between 35 and 120, while those employed with luminescence are between 100 and 255. WebSo the detector needs higher sensitivity and lower dark current to achieve a better signal-to-noise ratio, resulting in higher dynamic range and in better contrast between the sample’s structure and the background. ...
