47 7 Method setup 8 Advanced operation 8.1 Introduction By using the Analysis time setting in the autosampler method and not allowing the timer to finish countdown during the first un-freeze signal, the autosampler is prevented from starting the next injection cycle until the chromatography run has been performed. At the end of the UNICORN method the analysis timer countdown is re-activated and completed, leading to the start of the next injection cycle. In this way the samples are kept in the cold compartment until the next purification run starts. Note: When the autosampler runtable is started (first injection) it will immediately begin to load the first sample into the loop. 8.2 Run states Description During advanced operation three run states exist for the autosampler. Initially the autosampler injection valve is in INJECT position. Stage 1 2 State description Preparing for next injection 1 Needle goes to sample vial. 2 Alias injection valve switches to LOAD. 3 Loading sample loop with programmed volume. Injection freeze 1 Autosampler is paused, waiting for the un-freeze signal (UNICORN digital out 1) to go from 0 (default) to 1. 2 When the un-freeze signal is received, the Alias injection valve switches to INJECT and the sample loop is now part of the ÄKTA instrument flow path. The sample will be injected onto the column when the injection valve on the ÄKTA instrument is turned. 3 A wash routine is performed in the autosampler after each injection.

48 8 Advanced operation 8.2 Run states Stage 3 State description Analysis timer running 1 Analysis time that has been set in the Alias method starts to countdown when the un-freeze signal is received. Analysis time countdown will pause/hold when the unfreeze signal ends. 2 Analysis timer is continued by sending a second un-freeze signal in the end of the UNICORN method. The timer will then continue to countdown remaining time. 3 When the analysis timer has counted down to zero a new cycle starts, back to stage 1.

When the un-freeze signal is not present (UNICORN digital out 1 set to 0), the countdown will pause/hold but the state for the autosampler will still be Analysis timer running and a new cycle is NOT initiated. To enable communication between the ÄKTA instrument and the autosampler, digital out signals have to be added in UNICORN software. 48 Connect Alias autosampler to ÄKTA pure or ÄKTA avant Instructions AC

In the method, set Analysis time to 0.20 min Set up the UNICORN method Add two un-freeze events UNICORN method, see Section Illustration of the Run states, on page 48 Principle The principle of the method is described below. Stage 1 2 Description The first un-freeze event is located before the sample application phase and should have a duration of 5 seconds. This un-freeze event causes the injection valve of the autosampler to be set to inject position. The analysis timer starts to countdown but pauses/holds after 5 seconds. The autosampler is still in the state Analysis timer running, preventing the autosampler from starting the next injection cycle. The autosampler remains in this state until the second un-freeze event is sent to allow the Analysis timer to continue and finalize the countdown. The second un-freeze event is located at the end of the method and should have a duration of 0.40 min, to allow the analysis timer to continue and count down the remaining time, including delay times. When the analysis timer has counted down to zero a new cycle starts and the next sample is placed in the autosampler loop. Connect Alias autosampler to ÄKTA pure or ÄKTA avant Instructions AC 49

52 8 Advanced operation 8.3 Set up the methods for advanced operation Additional information and tips for the UNICORN method Additional information and tips for the UNICORN method Delay sample application in UNICORN method Miscellaneous phase - Pause timer If the sample loading for the next injection does not finish before the UNICORN Sample Application takes place, a pause needs to be introduced. This is achieved by adding a Miscellaneous phase before Equilibration. In the Phase Properties dialog, check the Pause timer checkbox and set the time as indicated in the table below. Note: The time should be set so that the UNICORN runtime before Sample Application and the pause time are sufficient for the autosampler to finish loading the sample in the loop. The table below shows the time needed for the autosampler to fill the loop depending on the injection volume. Injection volume (ml) Time to fill the loop (sec) Connect Alias autosampler to ÄKTA pure or ÄKTA avant Instructions AC

53 8 Advanced operation 8.3 Set up the methods for advanced operation Additional information and tips for the UNICORN method Miscellaneous phase - Method delay Alternatively, the Method delay option can be used. In that case a delay volume has to be set. Note that you must calculate how long time the set delay volume represents, considering the current flow rate. Adapt length of UNICORN method prior to sample application: Another alternative is to omit the Miscellaneous phase and to adapt the length of the phases prior to the sample injection. For example, extend the duration of the equilibration phase so that the time is sufficient for the autosampler to fill the loop. Note: If samples with different volumes are scheduled to run, a scouting table could be created to adapt the pause timer, method delay or other parameter used to ensure that there is sufficient time for the autosampler to fill the loop before the sample injection. Add error handling phase in UNICORN Optional, a user defined phase for autosampler error handling can be added. Insert the error handling user defined phase directly after the Method Settings phase.
