4 Controlling the Sampler
Methods and Sequences
The sampler is usually controlled by a sequence, which is a list of samples to
be analyzed. It contains:
• Where to find the sample
• What method to use to analyze the sample
• How to measure and inject the sample
• How to generate a report of analysis
A method is a collection of setpoints (temperatures, times, etc.) that controls
the operation of a gas chromatograph.
The combination of a sequence and the methods it specifies provides complete
control over the analysis of up to 100 samples. However, the specific details
differ depending on the hardware and software used, so you are referred to
other documents for that information.
This discussion is limited to sampler-specific details. For setting up methods
and sequences see your GC documentation.
