current amplification

current amplification

[′kər·ənt am·plə·fə′kā·shən]
(electronics)
The ratio of output-signal current to input-signal current for an electron tube, transistor, or magnetic amplifier, the multiplier section of a multiplier phototube, or any other amplifying device; often expressed in decibels by multiplying the common logarithm of the ratio by 20.

Using a UV glass envelope, the R928 has high quantum efficiency (QE), high current amplification, good signal-to-noise ratio and a wide spectral response from UV to the near infrared (NIR).
The technique avoids the problems associated with current amplification methods, including contamination from previously amplified DNA.
