For the measurement of the 02.07.99 (morning and afternoon) was the 
refrigeration only incompletely function-ready, why the C4-Werte and acetone 
were not grasped reliably and don't appear therefore (-98). the C5-Werte was 
not grasped partially quantitatively completely, is however nevertheless 
carried along, since she/it to\062 80% was grasped.
Otherwise, the data-cancellations restrict themselves to single components, 
that are auswertbars not or badly.  These are marked with -98. The data-points 
below the NWG of the respective component are marked with -99.
The Peak identified as acetone becomes ev. from other C5-Komponenten, 
especially n-pentene, overlaid. Acetone should amount the main-share however. 
This Peak was excluded from the sum (with another Responsfaktor assesses), 
since he/it is considered secondary-product for the most part.
Unknown or uncertain components (especially such with O-Atomen like for example 
Ethanol) certainly is not quantifizierbars (Responsfaktor / 
Durchbruchsvolumina) and is not appraised therefore.
The value identified as Isopren can be overlaid by trans-2-Penten. Since the 
simultaneously appearing component lies cis-2-Penten under the NWG however, can 
be assumed that the main-part is Isopren. This can be explained with the 
relatively high reactivity of the two components, that leads in the summer to 
it, that both components are wegreagierts and are verifiable with the 
flight-measurements no longer. The emissions of the Isoprens are partially 
rather high against it in the summer.
