    Torrent s5 pH graph

    Hi there,
    I am adding my pH graph after initialization (*Attach Files).
    Are these values good ? pH values about 7,5 -and that is good- but I cannot sure about the graph.
    What is your opinion? Thanks !

    Hi missphelps,

    Thermo Fisher recommends not to use the init plot as it can be open to misinterpretation. Saying that, your graph shows a typical reagent check profile with the nucs rising steeply before decreasing. The purple W2 line should also rise quite steeply before stabilizing.

    If the graph deviates a lot from what I describe above (for instance when the signal is very messy or noisy), then it is recommended to repeat the reagent check from the System Tools menu. Often it will look better after repeating the reagent check. When the results don't improve, then reach out to the Thermo Fisher Technical Support team.

      Hello missphelps,
      Hope you didn't waste a chip on that run. The signal differential between all of your nucleotides and the wash buffer should be close to 1000 or greater for any cartridge on the S5.

      Good luck...

        Nine Things a Sample Prep Scientist Thinks About Before Sequencing
        by SEQadmin2


        I’m not a sequencing expert. I’m a purification scientist who uses NGS to evaluate workflows my group develops. With this perspective, we think about the sample first and the NGS workflow second. The sequencer is an exceptionally honest reporter, but it can only report on what you give it, so whether you get clean, interpretable data from an NGS workflow is largely determined before you begin.

        Here are nine questions we think about, in roughly the order they matter, before...

        From Collection to Sequencing: Why Sample Preparation and Preservation Define Sequencing Data
        by SEQadmin2


        Data variability is still an issue in sequencing technologies despite the advances in reproducibility and accuracy of these platforms. But the problem does not originate in the sequencing itself, but in the previous steps, before the sample reaches the sequencer.


        The first step is collection, followed by preservation and sample preparation for analysis. Most scientists overlook those steps, but not being careful might just be skewing the experiment’s results.
