Fireside chat: The right tools for the job

Join us for a presentation and interview with Silliker moderated by Mars Inc.’s Jerome Combrisson, as we find out how one can select the right food microbiology testing tools.

Selecting a testing method is often a conundrum.   

How do you establish what the most important method performances criteria are among such a long list of accuracy, specificity, sensitivity, trueness, limit/probability of detection…?

What is the scope of method and the validated scope by certification bodies?

Which type of testing should be used to make sure the method is fit for purpose for the lab and its routine samples?

If you’re sick of puzzles and want clear, expert advice, join us for this engaging one-hour session, in which we’ll hear from expert Wendy McMahon as she offers tips and tricks that benefit from her years of experience in the field.

Following her presentation, Wendy will sit down with Mars Inc.’s Jérôme Combrisson in an insightful one-on-one discussion.
