The VITROCELL® VC 10® CHEMCONTROL Smoking Robot is specifically developed for the chemical and biological analysis of single puffs. The effects of whole smoke as well as the gas phase of each individual puff can be analysed by a special smoking regime and sampling unit . Highly flexible smoking parameters combined with the compliance to ISO as well as Health Canada smoking regime requirements make the VC 10® CHEMCONTROL an efficient and extremely powerful analysis tool. Special configuration for VC 10® CHEMCONTROL Individual sampling points allow separate analysis of 8 puffs per cigarette. The puffs 1 to 8 are guided to a total of 8 individual sampling points, where e.g. impingers or other analysis tools may be placed. The base robot is as above. 4 Cigarettes are loaded and lightened automatically. The unique valve and purging system allows for the following regime: ○ Each first puff of cigarettes # 1 - # 4 is directed to sampling point # 1. After that there is the choice to purge the system. For this purpose the valve towards the cigarette holders is closed and the valve CHEMCONTROL Feature Whole smoke and gas phase analysis of single puffs for Smoking Robots VC 10® / VC® 10 S-TYPE towards the purging gas (e. g. Synthetic Air) is opened. The pump is performing 1…5 purging puffs. Thereafter the valve for the purging gas is closed and the valve towards the smoke ports opened. ○ Each 2. puff of cigarettes # 1 - # 4 is directed to sampling point 2. Then purging takes place in the same way than above. ○ Each 3. puff of cigarettes # 1 - # 4 is directed to sampling point 3. Then purging takes place in the same way than above. ○ Same procedure for 4. until final puff 8 (or a fraction of final puff) which is directed to sampling point 8. Then purging takes place in the same way than above. 136
