  1. MSQ Plus North America Sales TrainingChapter 2 – MS Modules Beta Training Version A 5-Jan-2012

  2. MSQPlus beta Sales Training Program Goals • Transfer general knowledge of the MSQPlus, and the competitive landscape, our market position in order to better sell the product. • Provide feedback on beta training modules to optimize them prior to launch to the NA Sales Team for chromatography/Advanced Detection. • Impact on MSQPlus order receipts within the 1st quarter of 2012 • Resource within your region for MSQPlus sales

  3. MSQPlus beta Sales Training Attending

  4. Agenda for today’s MSQPlus training program • Feedback and Responses to Session #1 Training • Functional modules common to all MS systems

  5. Feedback Session #1 slide 12 - Basic MS session is too busy and hard to find main points.

  6. + + + + + + + + + + + + + + + + + + + + + Session #1 Slide #12 Mass Spectrometer: Basic Schematic LC Sample Inlet Data System Ionization Source Mass Analyzer(s) Detector + + Creation of Ions Mixture of Solvent and Compounds Separation of Ions Detection of Ions Mass Spectra

  7. Feedback I would eventually like to see a “cheat sheet” of questions that we could use on sales calls with customers so that we can qualify them and understand what MS would suit their application best.

  8. Cheat Sheet Questions – What MS is best for you? • Cheat Sheet Questions: • Clean samples or matrix samples? • IC/Low mass? • Ease of use? Already using Chromeleon? • Known or unknown samples? • Proteins/high mass/high resolution/nano flow? • Rapid separation?

  9. Feedback • I would like a consolidated definition of MS terms – like a glossary: • Atmospheric Pressure Ionization: ESI, APCI • LC/MS vs GC/MS • API vs EI as it refers to a mass spectrum & library searching • CID • MRM, SRM • Adduct • Fragmentation • *most reps like the customers we will sell to do not understand these terms. The reps need to be able to explain them and understand them. • Check-out today’s training session and the MS Apps Guide & Glossary of MS terms sent earlier today….

  10. Feedback • I would like an Introduction to MS Components • Review a schematic of the source components • Discuss how LC/MS works. ESI vs APCI • Discuss CID and how it works. • Discuss +/- ion switching and hi/lo cone voltage • You may want to throw a slide in that discusses how GC/MS works • Check-out today’s training session….

  11. Feedback • Would like a review on How to Interpret Mass Spectra • Discussion of API spectra. • Discussion about positive and negative ion spectra. • Interpretation of spectral results. • Comparison of GC/MS spectra to LC/MS spectra (eg. GCMS Libraries, no commercial libraries for LCMS, generation spectral libraries with LCMS CID data). • Check-out today’s training session…. • Also check out Fred McLafferty’s, Interpretation of Mass Spectra or his ASMS Short Couse

  12. Feedback • I need more on the advantages & limitations of using MS in the determinations of unknowns. • Single state MS systems can provide molecular weight and some structural information – useful in unknown determinations. • Single stage MS systems have their niche primarily in analyte confirmation, low cost, and ease of use. And for us, ICMS. • MS/MS high resolution instruments provide more specific information to help identify unknowns.

  13. Feedback • I need more on the advantage of using MS/MS over MS only detection. • MS/MS instruments can be more sensitive relative to determinations of an analyte in dirty or high matrix samples. • MS/MS instruments can provide more specific, product ion information, better enabling sample confirmation. • MS/MS high resolution instruments provide more specific information to help identify analytes. • MS/MS systems can provide faster sample analysis due to reduced sample prep requirements in high matrix samples. • Compared to MS only systems, MS/MS instruments are generally higher cost to purchase & operate, require more sophisticated users.

  14. Feedback I would like more information on how the MSQPlus is used. The LCMS Applications Guide consolidates most MSQPlus applications. Environmental – Water Testing Industrial – Food & Beverage, Forensic, Chemicals

  15. Agenda for the NA MSQPlus training program • Comparison of Detectors: General, MS only, MS/MS • Functional modules common to all MS systems • MS Features and their importance to customers • MSQPlus Strengths, Weaknesses, Opportunity, and Threats • Decision Tree to better understand when to pursue an MS only order or an MS/MS order

  16. MSQPlus beta Sales Training By the end of this module you will know…. • The Basic Modules of all Mass Spec Instruments. • The Importance of the Basic MS Modules to Customers.

  17. MS Basic Modules Overview Understanding this information will help you identify the proper MS product for your customer.
