How do I troubleshoot my GC?
Minimize dead volume in the GC system; verify proper column installation, proper connectors, proper liners, etc. Verify injector and detector flow rates and adjust if needed. Verify make-up gas flow and adjust if needed. Increase GC oven programming rate.
What is GC maintenance?
Description. Routine maintenance is an important step in getting the best performance from your gas chromatograph. There are numerous parts just in the inlet that require regular replacement including inlet liners, liner O-rings, septa, ferrules, and, for some instruments, inlet seals.
What is GC course?
Certificate Course on Gas Chromatography.
What is GC MS training?
GC-MS training for the Chromatographer A course designed to highlight the powerful possibilities of GC analysis with mass spectral detection. Tuning and tune reports will be explained and instruction given in the use of tune reports as a powerful diagnostic tool.
What causes no peaks in GC?
Re: no peaks showing in GC Chromatogram You might need to enable a viscocity delay or the injection could be very noreproducible due to insufficient time to draw in sample or getting air in. Also make sure there are enough sample strokes (I usually have 5 or 6).
What is a common maintenance procedure for a GC system?
Inlet hardware Every 6 months Check for leaks and clean. Every year Check parts and replace when parts are worn, scratched or broken. Inlet gold or stainless Monthly* Check for scratches, corrosion, or build-up of non-volatile sample components and steel seal replace if dirty.
When should I change my GC column?
You need to change your column when it can no longer do its job, in other words when the quality of the results is no longer fit for purpose. BEFORE you change your column check that the inlet is in good condition, since this is a far more common cause of the problems that you list.
How long does gas chromatography training take?
Time for course completion You can complete the program at your own convenient pace. Generally our registrants take 3-4 months to complete the program.
How long does gas chromatography mass spectrometry take?
The 5-day Complete GC & GC-MS course is built from the 3-day Practical Essentials of GC & GC-MS and the 2-day GC & GC-MS Clinic courses to provide a complete training solution enabling you to understand your Gas Chromatograph or GC-MS instrument, develop applications, troubleshoot & maintain it.
What is gas chromatography mass spectrometry used for with fuel analysis?
Analyzing small and volatile molecules When combined with the detection power of mass spectrometry (MS), GC-MS can be used to separate complex mixtures, quantify analytes, identify unknown peaks and determine trace levels of contamination.
