The TurboMatrix 650 ATD offers the Sample Integrity Testing

down menu select
Load ISTD on Tube. this mode of
operation will inject an internal standard onto the
selected tubes.
3. Go to the
Run tab and select the Tubes button and
indicate the tube numbers and the run. The tube will be
injected with the internal standard but not analyzed.
4. In the previously select tubes inject a different internal
standard and run them through a new method (use a two
stage desorb method to analyst the samples).
5. The second internal standard will allow you to evaluate
your tube desorption and injection of your sample.
6. The first internal standard allows you to evaluate if any
degradation has occurred to the sample. loss of the first
internal standard can suggest loss of sample prior to the
analysis.
