Interpretation of Mass Spectra

1650 (USD)	H4063A	3 Day(s)	Lecture Only
2000 (CAD)

Description:

Training Units 16 (US) | 20 (CA) What are Training Units?

This course is designed to present the fundamental concepts necessary to obtain high-quality data in SCAN mode from a GC-MS System for spectral interpretation purposes. The most commonly employed tools used in identifying compounds based on their mass spectra are introduced, the physical reasons for their efficacy explained, and their use reinforced through problem solving. The most common decomposition mechanisms responsible for fragment ions will also be introduced.

Outline:

Day One

GC-MS Data Structure

Chemistry Review

Data Acquisition

Day Two

Introduction to Interpretation

Goals

Structural Information

Spectrum Appearance

Elemental Composition

Use of Isotopic Abundance

Rings and Double Bond Calculations

Deducing Elemental Composition

Day Three

The Molecular Ion

Nitrogen Rule

Logical and Illogical Neutral

Losses

Abundance vs. Ion Structure

Library Searching

Prerequisites:

Undergraduate training in organic chemistry and at least six months experience obtaining spectra with a modern mass spectrometer and data system.

Equipment:

Please bring a calculator.

Student Profile:

An advanced GC-MS operator or GC-MS supervisor with responsibility for identifying unknown spectra or evaluating MS library database search results. This course provides a more comprehensive introduction to interpretation than H5313A and H5319A.
