It is suitable for detecting low volatility substances, preferably substances that volatilize below 100 degrees Celsius. Because most samples contain water, more than 100 degrees Celsius will also inject water vapor into the column and damage the column.

The temperature of the headspace sampler can be added to 200 degrees Celsius, which means that it is theoretically possible to detect substances that can be vaporized without decomposition within 200 degrees Celsius.
The headspace injection method has a clean peak, and it is better for substances that are inconvenient to be extracted by a solvent.

This is the end of the introduction of What sample detection is suitable for headspace injection? I hope it can help you.
