Load Internal Standard (ISTD) on Tube
If the instrument has been equipped with the Internal Standard
option, a metered volume of an analytical standard can be loaded
onto a sample tube. This can be done prior to the sample being
collected onto the tube or prior to the desorption of the collected
sample onto the cold trap.
Continuous Online Monitoring— ‘On-line’ is a continuous
sampling mode in which sample is drawn through the ATD/TD and
sampled at regular intervals.
During continuous monitoring, the sample is drawn in through an
empty sample tube and onto the cold trap.
The continuous online monitoring accessory is available as an
option. Generally this option is installed at the factory. Contact the
PerkinElmer service department for further information.
