Fraction Collection

Devices and Trays

With snippets such as Sampler Device or Fraction Collector Tray you add graphical representations of your sample containers to your template. This allows you, for example, to locate the drawer position of a tray in a multisampler, or to locate the sample on a tray.

The preview images always show example data.

Fraction Delay and Results

The Fraction Delay and Fraction Results snippets help you when you use a fraction collector.

With the Fraction Delay table, you get an overview of your system's fraction delay (delay volume or delay time): At the precise time the detector finds a peak start or end, the detected compound is in the detector cell and not at the diverter valve, therefore it would be too early to switch the valve to the collect position. The valve switching has to be delayed until the compound has moved from the detector cell to the inlet of the diverter valve.

With the Fraction Results table, you get an overview of the collected fractions.

The delay time is shown as variable if the start delay time varies across injection fractions.
