<strong>Fast</strong> <strong>Discrete</strong> <strong>Dynode</strong><br />
<strong>TOF</strong> <strong>Detectors</strong> <strong>from</strong> <strong>ETP</strong><br />
PRODUCT DATA<br />
<strong>ETP</strong>’s fast discrete-dynode detectors are<br />
rapidly gaining wide acceptance as the<br />
preferred detector in Time-Of-Flight mass<br />
spectrometry. They offer a unique<br />
combination of narrow pulse width, large<br />
dynamic range, rapid recovery <strong>from</strong> intense<br />
ion signals, and operational and<br />
mechanical robustness that is unsurpassed<br />
by any other type of detector.<br />
• <strong>ETP</strong>’s fast <strong>TOF</strong> detectors model 14880 (left) and 14882 (floating version, right).<br />
