Queue Up Samples to Run Automatically​​

One of the most popular features of the ACCQ Prep, when connected to an autos ampler, is the ability to create a queue of samples to be run automatically—great for walk up environments and for labs running many different samples on a regular basis, often unattended overnight. When connected to our AS 2x2 or AS 4x4 Auto Sampler, an additional user interface option becomes available on the ACCQ Prep. This Sample Queue option appears at the bottom of the main screen and lets users toggle between the Sample Queue interface and the traditional Peak Trak interface.

The Sample Queue capability is built on the need for higher productivity via workflow automation:

1. One-touch selection of installed columns and their defined methods.
2. Input RT of target compounds as obtained from calibrated analytical systems.
3. Add one or more samples to be run automatically in sequence.
4. Open the Method Editor to modify the advanced settings for a specific sample.
5. One-touch access to MS detection ions or UV threshold (if enabled via Instrument Configuration).
6. Select a unique rack position for each sample: choose a specific rack or NEXT TUBE or NEXT RACK.
7. One touch sample-injection options: total volume, number of injections, and sample position.
8. Import sample lists into the queue (Peak Trak version 4.2.68 or later). Simply export the COLUMN/METHOD list via USB, create your sample queue parameters on a PC using Excel, and import back into ACCQ Prep. For full details on sample list import

Sample Queue makes open access easier and more efficient. With an ACCQ Prep system already in use by one analyst, the walk-up access lets other users set up samples to have them purified automatically once any other programmed runs are complete.

Another great thing about the Auto Sampler module connected to Peak Trak is that valve and sample probe wash steps are automatically built in to eliminate cross-contamination between users.
