Quantifcation methods data base*: Quanpedia™ - a database for storing and sharing user defned LC/SIR acquisition and associated processing methods for the targeted quantifcation of named Database entries for a number of applications are also provided. Quanpedia software item included with the purchase of the TargetLynx™ Application

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

SIR acquisition window assignment: Multiple SIR experiments can be scheduled (manually or automatically using database) using retention time windows to optimize the cycle time for each monitored. If required, SIR retention time windows can overlap partially or This ensures that SIR data acquisition rates will be optimal for the quantifcation analytes in a given assay.

Why employ ms4sale?

Your MS options are far reaching, so why use Jaytee Biosciences? Unlike other providers of used MS equipment, we have the ability to completely:

This is because we employ both skilled engineers and experienced scientists, which allows us to provide a value added solution.

When we acquire an MS system, we are not simply re-listing for sale with a mark-up. We service,test and run the system, producing chromatographic and mass spectral data before we advertise. When our clients ask us whether a particular system is suitable for their application, we provide detailed information, and offer a pre-visit service whereby you send us your sample, which we run and prove for your benefit. Why? Because we can, and because it helps you make the right choices.

Ask yourself why other companies are only showing stock images, with no data or proof of performance - because we have the skills, you get the peace of mind and the ongoing support for your method.

Finally, this is at no added cost, since our pricing policy is flexible, and therefore competitive - a win/win!

Jaytee; No take overs/mergers in over 35 years - just professional, solid, skilled on going support.
