Quantification methods database*Quanpedia™ – a database for storing and sharing user defined LC/MRM acquisition methods and associated processing methods for the targeted quantification of named compounds. Database entries for a number of applications are also provided.  Quanpedia is an optional software item included with the purchase of the TargetLynx Application Manager.

MRM acquisition rate assignment*Dwell time, inter-channel delay time, and inter-scan delay times for individual channels in a multiple MRM experiment can be automatically assigned (using the Auto-Dwell feature) to ensure that the optimal number of MRM data points per chromatographic peak are acquired. The Auto-Dwell feature can dynamically optimize MRM cycle times to accommodate retention time windows that either partially or completely overlap. This greatly simplifies MRM method creation, irrespective of the number of compounds in a single assay, while at the same time ensuring the very best quantitative performance for every experiment.

MRM acquisition window assignment*Multiple MRM experiments can be scheduled (manually or automatically using the Quanpedia database) using retention time windows to optimize the cycle time for each MRM channel monitored. If required, MRM retention time windows can overlap partially or completely. This ensures that MRM data acquisition rates will be optimal for the quantification of all analytes in a given assay.
