Chapter 6Instructions for building acquisition batches and running the queue samples can be found inthe Analyst manual and are no different when involving the Coulochem III detector anddriver. Refer to the manual for details.6.2 Viewing the Progress of a Coulochem III AcquisitionAs the Analyst program manages the acquisition of each sample in a batch, it dispatchesinformation at various times to each of the instruments or drivers in the active hardwareprofile, including the Coulochem III driver. Just prior to the start of the pre-run phase,Analyst provides the Coulochem III driver with all of the Coulochem III detector-specificconfiguration and method data for the sample that is about to be run. Analyst obtains this datafrom the acquisition method file (and its attached Coulochem III method data). TheCoulochem III then updates its interface with these values.As the run begins its pre-run phase, the Coulochem III driver automatically switches to thePre-Run tab and begins to display the pre-run time in the Acquisition status region at thebottom of the driver window (Figure 6.2). The Pre-run phase is also designated in yellow inthe Status indicator in this region.Figure 6.2. Acquisition Status Bar During Pre-Run Phase.The duration of the pre-run phase depends on the parameters activated and assigned in thePre-Run tab. After the pre-equilibration time designated in the Pre-equilibrate for field, thedriver will extend the pre-run phase by as much time as needed for the thermal organizer toreach within 2° C of its setpoint (if activated and checked). If checked, the autozero isperformed only after the Pre-equilibrate for time has elapsed and the setpoint has beenapproached. An additional 15 seconds is added post-autozero to ensure adequate stabilizationfrom the autozero event.The acquisition phase begins immediately after the pre-run phase. The Coulochem III driverautomatically switches to the Timed Events tab and begins to display the run time in theAcquisition status region at the bottom of the driver window (Figure 6.3). The acquisitionphase is designated in green in the Status indicator.As the run progresses, and as each timed event is processed in the timed events grid, the lastexecutedevent is highlighted.44 Coulochem ® III Analyst Driver – Version 1.0User’s Manual
