Agilent Technologies: How to set MS Scan Parameters for your LCMS Experiment

  • Wait what?! Who knew!? There are so many things that a mass spec can do.

  • I've used it for years, yes this may be true.

  • I've processed some samples, more than a few.

  • But between me and you, I had no idea all the things it could do!

  • From sample prep to separation, you just won't believe…

  • All of the tips and tricks we have up our sleeve.

  • So, take a few minutes, about 15 should do.

  • And learn all the things your mass spec can do.

An easy to follow guide detailing how to set MS scan parameters for an LCMS experiment will be presented. Scan speeds for reproducible quantitation, chromatographic resolution, retention time definition, proper threshold adjustment for optimum datafile size, and how this can result in faster processing times will all be discussed.

Presenter: Rebecca Glaskin, Ph.D. (LC/MS Application Scientist, Agilent Technologies, Inc.)

Rebecca Glaskin is an LC/MS Application Scientist at Agilent with a focus on BioPharma applications supporting the LC-Q/TOF and IM-QTOF platforms. Prior to joining Agilent, Rebecca received her Ph.D. in analytical chemistry from Indiana University in the lab of Professor David Clemmer. While there she designed and constructed home-built instruments, pushing the limits of the mobility resolution that can be obtained with a circular drift tube for the separation of biomolecules (peptides, proteins, carbohydrates, and metabolites). While there, she also studied hydrogen/deuterium exchange of proteins in the gas-phase as a function of time and pressure. Rebecca then went to Boston University as a Postdoctoral Associate in the lab of Professor Catherine Costello to develop a database containing collision cross section values for glycans, peptides, and glycopeptides utilizing Agilent Technologies 6560 IM-QTOF. This database can be used to determine how the collision cross section is altered with the addition of individual saccharide units. The trendlines obtained from this database will be used to predict collision cross sections for glycopeptides based on the conformation and structure of the specific glycoform.

Presenter: Jim Lau, PhD (HRAMS LC/MS Application Engineer, Agilent Technologies, Inc.)

Jim Lau received his Ph.D. From the University of Colorado. There he worked in the laboratories of Peter Albersheim and Robert Shapiro. This work involved the structure elucidation of plant natural products and, in particular, elucidating the structures of oligosaccharides derived from plant cell wall polysaccharides. This work was done in the early days of LCMS and made use of DLI-LCMS and (at the time) recently invented Thermospray-LCMS.

After the completion of his Ph.D., Jim joined Hewlett-Packard to work on LCMS ionization techniques with Paul Goodley during the early days of Electrospray-LCMS. He then moved to work on field applications and collaborations with Hewlett-Packard’s LCMS customers. More than 30 years later, Jim continues to work with Agilent’s customers in High Resolution Accurate Mass applications of LCMS. While involved in many areas of HRAMS LCMS, his recent work has focused on the area of Screening/Qual&Quant of small molecules and on the high throughput confirmation of oligonucleotide synthesis.
