Does Clarity support Calibration Bracketing?


Yes, Calibration Bracketing is supported directly in Clarity since version 3.0.

What is bracketing?

The bracketing in calibration is a technique, when samples in a long  sequence run are evaluated to standards immediately preceding and  immediately following the respective samples. It is used to compensate  for instability of detector response during the run, for example typical  for electrochemical detectors.

1. In the Method Setup - Calculation, set the name for cloned calibration files used during the Calibration Bracketing.

The field enables the use of any text, however it is recommended to  use  variables appropriate to the calibration method (Line, Date and  Time, ...) (1).

2. In the Sequence - Sequence Options, check the Calibration Bracketing option.

This sets the sequence and calibration to the Calibration Bracketing mode (2). As every unknown sample series is demarcated by calibration standards and as such uses a single calibration file, calibration will  be cloned from the  previous calibration clone whenever an unknown  sample or blank follows the  calibration standard. In a newly cloned  calibration file, all responses other  than responses of the last series of calibration standards (only those standards  that follow the unknown  samples) are cleared.
