Specification

Instructions  

Samples for GC analysis on the Thermo Trace 1300 GCs are submitted to the chromatography service.

Sample preparation

Samples should be submitted in screw-top GC vials which are available from the GC submission points around the lab. Sample vials need to be filled to at least 50% depth in order for the injection needle to be able to draw up sample.

Computer submission

Samples should be labelled with a GC label containing a submission number and be placed in the appropriate tray on the bench opposite the prep room. The details for your sample and the experiments you require should be filled in on the google form accessed by the submission hub. Your samples will be queued up on the autosampler by a technician and the results will usually be available the next day.

Accessing data

GC chromatograms are returned electronically. In order to locate your data, you will need to identify the date your spectra were submitted and which instrument your sample has been recorded on in the GC submission form below. 

Results are then accessible via FTP from ftp://chemtl.york.ac.uk/TGC/. Select the instrument used to record your chromatogram, then the file type required and the date of submission. Samples are stored by GC sample number.

Standards

In addition to your data, standards are often recorded to aid interpretation of chromatograms. These will be stored in the same folders (Instrument/file type/date) and will have been recorded in the same sequence as your sample. Standards will be clearly labelled and should be used to aid identifying components by matching retention times.

Columns available

30 m TG-SQC

A general purpose column suitable for the separation of non-polar analytes, and especially fatty acid methyl esters (FAMEs).
