Amersham Typhoon Operating Instructions 29193226 AC
Description
Selects a pre-programmed method for
scanning.
Note:
In the Fluorescence mode, up to five sequen-
tial scans can be performed in one method.
Selects the pixel size for scanning.
A sample with a smaller pixel size can be
analyzed in more detail, but the scanning
time and the image file size will increase.
Selects the voltage of the photo-multiplier
tube (PMT).
The higher the PMT voltage, the higher the
sensitivity. However, a too high PMT voltage
may lead to image saturation and a high
background. It is therefore recommended
to optimize PMT voltage for each sample
type.
Sets the voltage of the PMT automatically
based on a pre-scan.
Selects the scan speed: Normal or Slow.
Normal scan speed is recommended for
most applications.
To reduce background noise, use a slow
scan speed. A slow scan speed reduces noise
by data averaging.
Adds additional scans.
Changes between scan areas (DIGE method).
Adds an annotation (DIGE method).
An annotation can be deleted with the small
cross.
