GC and GC/MS Course Scheduling and Fees
Each of the classes are listed as one-day modules. Contact DSB Scientific to schedule the modules you require.

Course fees:


For On-Site Training, a DSB Scientific Instructor comes to you. Courses are typically conducted using MS PowerPoint, so you will have to supply classroom space with projector for the presentation. Fees are fixed at $2500 + travel/lodging per module. We cannot supply an instrument for On-Site Training. (Note: we will provide a per module discount if you schedule three or more modules to be taught in one location during one week).

Basic GC Theory

Introductory GC class designed for those not familiar with gas chromatography. We have used this course as a refresher for an Analytical Chemist who has not dealt with GC for some period of time and for technical sales staff new to selling GC related equipment.

Topics Covered:
  • Types of Chromatography
  • Basic Theory of Chromatographic Separations
  • Factors affecting the separation in GC
  • Basic instrument design
  • Columns in detail
  • Inlets in detail
  • Detectors in detail (except Mass Spectrometer)
  • Some basic applications

Quantitative Analysis with Gas Chromatography

This course was designed to help the analyst new to GC become proficient with quantitative analysis.

Topics Covered:
  • Ideas to consider in quantitative work
  • Basic Statistics
  • Limits in the Method (detection limits, etc)
  • Evaluation and Validation of Methods
  • External Standard Method
  • Internal Standard Method
  • Interferences
  • Reporting of Quantitative Data

Basic Maintenance and Troubleshooting of the Gas Chromatograph

Best taught with a GC on hand, this course outlines the basic procedures for GC maintenance and repair. For the analyst new to GC, this course assumes no hands-on GC background and little or no formal GC theory training. As such, it is an excellent companion course to the Basic GC Theory course outlined above. A version of this course was used to familiarize new sales staff with GC related equipment.

Topics Covered:
  • Tools and other supplies useful for GC Maintenance
  • Column installation-techniques and tips
  • Carrier flow control
  • Split/Splitless and Direct Injection Inlets (septa, liners, and seals)
  • Flame Ionization Detectors (jet cleaning/replacement) (other detectors also available upon request)
  • Troubleshooting chromatography problems

The Mass Spectrometer Detector

This class was designed to focus on the mass spectrometer as a GC detector. It is a good overview of mass spectrometry for those new to the field and not planning to use the mass spectrometer as a stand-alone instrument. The course has been taught as a refresher and for new technical sales staff.

Topics Covered:
  • General Outline of Mass Spectrometry
  • Interfacing to the GC
  • Vacuum Systems
  • Ionization and Detection
  • Mass analyzers, general theory
  • Mass analyzers, considerations for use as GC detector
  • Operational modes of the mass spectrometer-Scan and SIM
  • Autotuning vs. Manual Tuning
  • Some words on tuning frequency and techniques
  • Some applications in qualitative analysis
  • Quantitative analysis by Isotopic Dilution

Basic Mass Spectrometer Maintenance and Troubleshooting

This class is designed to help the analyst new to using a mass spectrometer detector learn basic system maintenance and repair tasks. By performing some of the basic tasks in-house, service call costs and down-time will be reduced.

Topics Covered:
  • Overview of common maintenance and repair tasks
  • Vacuum system maintenance
  • Vacuum system troubleshooting (leak checking)
  • Using tune data to troubleshoot common problems
  • Ion source maintenance and troubleshooting
  • Analyzer maintenance and troubleshooting
  • Detector maintenance and troubleshooting
  • Identifying electronics problems

The GC and GC/MS Analyst in Court

This course, taught by a court qualified expert witness in Chemistry, will outline some of the considerations for clear presentation of scientific data and principles on the stand. It is a useful class if there is a chance that your analytical results may be challenged in either civil or criminal court.

Topics Covered:
  • Overview of court procedures
  • Qualifications as Expert
  • Giving Expert Testimony, general ideas
  • Discussing GC and GC/MS on the witness stand
  • Handling common aggressive questions
